Yes, for mid-to-large scale mining operations, we establish long-term supply agreements. This stabilizes your OPEX against global chemical market fluctuations and guarantees priority production scheduling.

Standard industrial cyanide often tests at 97%. AuCyan™ guarantees ≥98.3% ריינקייַט. This higher concentration ensures a massive surplus of free CN⁻ ions, which rapidly penetrates complex ore matrices, slashing required leaching times and maximizing yield.

AuCyan™ maintains sodium hydroxide (NaOH) levels around קסנומקס%. This provides excellent pH buffering to prevent premature hydrolysis (off-gassing) without causing severe calcium scaling in your Heap Leach drip emitters and pipelines.

AuCyan™ is manufactured as solid white briquettes (tablets). This shape minimizes dangerous dust generation during handling, dissolves rapidly in mixing tanks, and is highly stable during long ocean transits.

Copper aggressively consumes cyanide. AuCyan™’s ultra-high purity ensures that even after base metals (like copper or zinc) consume their stoichiometric share of CN⁻ ions, sufficient active cyanide remains to rapidly dissolve the target gold particles.

AuCyan™ features an ultra-low moisture content of ≤קסנומקס%. High moisture leads to chemical degradation and hazardous ammonia gas buildup inside the drum. Our dry formulation guarantees long-term stability in tropical climates.

No. With insoluble substances strictly controlled at ≤קסנומקס%, AuCyan™ dissolves cleanly into a clear liquor, preventing sludge buildup in your tanks and protecting expensive slurry pumps from premature wear.

It is exported in UN-certified 50kg hermetically sealed steel drums or 1,000kg reinforced wooden boxes. Both options feature a heavy-duty, heat-sealed Polyethylene (PE) inner liner to completely block atmospheric moisture.

AuCyan™ Sodium Cyanide is strictly classified under יו.ען., באַצייכנט ווי אַ Class 6.1 Toxic Substance (Dangerous Goods) under international maritime law.

While it varies by ore type, operators typically mix the solid briquettes with process water to create a high-strength stock solution (typically 10% to 20% NaCN by weight) before dosing it into the leaching circuit to maintain optimal PPM levels.

Absolutely. Silver extraction requires significantly higher cyanide concentrations than gold. AuCyan™’s extreme 98.3% purity is highly sought after by epithermal silver-gold operations (such as in Mexico) to satisfy massive reagent consumption.

When kept in its original, unbroken, UN-certified packaging within a dry, well-ventilated warehouse out of direct sunlight, AuCyan™ maintains optimal chemical stability for up to קסנומקס צו קסנומקס months.

Coconut shell carbon possesses a naturally dense, micro-porous structure perfectly sized for the [Au(CN)₂]⁻ complex. It offers significantly higher mechanical hardness and a much lower ash content compared to coal or wood-based carbons, minimizing fine gold losses.

In CIL/CIP tanks, the mechanical agitation is violent. If carbon is soft, it shatters into fine dust that carries adsorbed gold out into the tailings dam. AuCarb™’s ≥99% כאַרדנאַס ensures massive structural integrity, reducing attrition to near zero.

6x12 mesh particles are larger and coarser, commonly used in Heap Leaching (CIC) to handle high flow rates without clogging. 8x16 mesh particles are finer, offering higher surface area for faster adsorption kinetics in CIL/CIP tank agitation.

די ק-ווערט (Adsorption Capacity) measures the total amount of gold the carbon can hold at equilibrium (e.g., ≥30 Kg/t). The ר-ווערט (Adsorption Rate) measures how fast the carbon loads gold. AuCarb™ AC60 excels in both, boasting R-Values ≥60%.

Platelets are flat, poorly shaped carbon granules that can easily slip through inter-tank screens, carrying gold to the tailings. AuCarb™ guarantees a platelet content of ≤קסנומקס%, ensuring precision screening and maximum gold retention.

Yes, AuCarb™ features a pristine pore network that releases gold complexes rapidly under high-temperature/high-pressure elution conditions (both Zadra and AARL), resulting in a highly concentrated pregnant solution for electrowinning.

Absolutely. After acid washing and elution, AuCarb™ can be passed through a rotary kiln at ~700°C. Its high density allows it to recover over 95% פון איר אָריגינעלער טעטיקייט over multiple cycles, significantly reducing OPEX.

Preg-robbing ores contain natural carbon that prematurely steals dissolved gold. To combat this, you need an activated carbon with colossal kinetic speed. AuCarb™’s extreme CTC and Iodine numbers allow it to instantly out-compete native carbon for gold complexes.

High ash content indicates inorganic impurities that can blind the carbon's pores and interfere with gold loading. AuCarb™’s ultra-low ash (≤קסנומקס%) ensures maximum pore availability and cleaner elution profiles.

While all carbon can adsorb organic matter (like flotation reagents or machine oils), AuCarb™'s specific micro-porous dominance creates a steric hindrance against larger organic molecules, keeping the pores open for gold.

We strictly pack AuCarb™ in 25 ק"ג שווער-פליכט לאַמינירט עלאַסטישע PE זעקלעך or 500kg bulk super sacks, ensuring the granules remain dry and uncrushed during global maritime transit.

AuLeach™ (GDA) is a revolutionary, eco-compliant chemical formulated to extract gold without the severe environmental toxicity of sodium cyanide. It provides comparable, and often superior, leaching kinetics.

Yes, AuLeach™ is certified globally as a Non-Hazardous general cargo. It bypasses toxic DG Class 6.1 legislation, meaning it requires no military escorts, reduces insurance premiums, and sails through customs smoothly.

AuLeach™ is designed as a direct drop-in substitute. Depending on the ore characteristics, it is typically dosed at a ratio of קסנומקס: קסנומקס צו קסנומקס: קסנומקס compared to your historical sodium cyanide consumption.

No. The guaranteed operational pH range for AuLeach™ is 10.5 - 12. This aligns perfectly with traditional cyanidation circuits, meaning you can continue using standard hydrated lime to manage slurry alkalinity.

Zero equipment CAPEX is required. AuLeach™ is fully compatible with existing Heap Leaching irrigation networks, VAT leaching pools, and CIL/CIP mechanical agitators. No mechanical retrofitting is needed.

AuLeach™ exhibits superior resistance to interference from arsenic and sulfur. When treating complex refractory ores, it frequently achieves faster leaching kinetics and a 2% to 5% higher absolute recovery rate compared to traditional cyanide.

Absolutely. Because it lacks the persistent toxicity of cyanide, treating AuLeach™ tailings requires significantly fewer chemicals (like SO2/Air or Hydrogen Peroxide), slashing your environmental compliance and detox OPEX.

Mine laboratories can test AuLeach™ concentration via a standard chemical titration method using a silver nitrate complexing agent and a rhodanine indicator, exactly as your metallurgists currently do for cyanide.

Replacing toxic cyanide with AuLeach™ instantly elevates a mining company's ESG profile. It eliminates severe occupational health risks, protects local watersheds, and drastically improves relations with local communities and governments.

Yes, the gold complex formed by AuLeach™ is perfectly compatible with coconut shell activated carbon. Pairing it with אוי-קאַרב™ ensures a seamless transition in your CIL/CIP recovery and elution phases.

As a non-hazardous solid powder, AuLeach™ is efficiently packed in standard Net 25kg woven bags with inner moisture-proof liners, making it extremely easy to handle and mix at the plant.

High-clay laterites form extremely viscous slurries in CIL tanks, causing massive mechanical shear. You must use אוקאַרב™ AC60 (≥99% hardness) to prevent carbon from shattering into dust and losing your gold to the tailings.

Silver requires twice the cyanide to dissolve compared to gold. In high-silver ores (like those in Mexico), you must utilize ultra-pure AuCyan™ (≥98.3%) to provide an overwhelming surplus of CN⁻ ions, ensuring base metals don't exhaust your reagent.

Yes, but freezing temperatures severely retard chemical kinetics. In high-altitude regions (like the Andes or Central Asia), using the extreme purity of AuCyan™ helps jumpstart and maintain the dissolution equation despite poor thermodynamics.

AuLeach™ is highly effective in Vat leaching. Because it is non-toxic, it significantly reduces the environmental risk of pool leakage contaminating groundwater, making it ideal for artisanal and mid-scale operations.

Scaling is caused by high calcium and poor pH buffering. AuCyan™ contains strictly controlled Sodium Hydroxide (NaOH ≤0.13%), which stabilizes pH without triggering catastrophic calcium carbonate precipitation in your irrigation network.

For Carbon-in-Leach (CIL) and Carbon-in-Pulp (CIP), 8x16 mesh AuCarb™ is the industry standard. It provides a massive surface area for rapid adsorption while remaining large enough to be caught by standard inter-tank screens.

Desert operations often use saline water, which lowers dissolved oxygen and slows leaching. The explosive dissolution rate of high-purity AuCyan™ helps compensate for this lack of oxygen, maintaining acceptable extraction kinetics.

A cloudy pregnant solution often indicates high ash content or soft carbon degrading into fines. Switching to AuCarb™, with its ≤3% ash content and ≥99% hardness, ensures a pristine, clear liquor for electrowinning.

Transition sulfides consume immense oxygen and cyanide. Pre-aeration and lead nitrate conditioning are recommended. Following this, dosing AuCyan™ ensures sufficient active cyanide is available to overpower the remaining cyanicides.

Flotation reagents, machine oils, or humic acids from topsoil can blind carbon pores. AuCarb™’s highly specific microporous structure inherently resists large organic molecules, keeping the vital pores open for the gold complex.

Both work exceptionally well. However, if the tailings dam is near a local community or sensitive watershed, re-processing with אוי ליטש™ eliminates further toxic accumulation and simplifies final site rehabilitation.

We exclusively transact under strict FOB (פריי אויף ברעט) China ports, or CIF (קאָסט, פאַרזיכערונג און פרייט) to your destination seaport globally.

נומ Due to severe international safety regulations and the unpredictable nature of cross-border rail infrastructure, we strictly prohibit the use of international railway transport for hazardous chemical exports. We rely 100% on secure maritime freight.

For landlocked nations, we ship CIF to the nearest strategic coastal transit hub (e.g., Port of Arica for Bolivia, or Port of Dakar for Mali). From there, your designated local forwarder manages the cross-border road trucking.

In countries like Indonesia and the Philippines, domestic RORO ferries often refuse to carry toxic DG Class 6.1 cargo. Because AuLeach™ is Non-Hazardous, it can be seamlessly loaded onto any domestic ferry as general cargo.

A standard 1x20' FCL typically holds 20 Metric Tons (MT) of AuCyan™ when packed in 1,000kg wooden boxes, or approximately 18 to 21 MT when packed in 50kg steel drums, depending on precise pallet configurations.

Our UN-certified wooden boxes and steel drums feature integrated, thick Polyethylene (PE) inner liners that are heat-sealed. This creates a hermetic barrier, completely blocking extreme atmospheric humidity during Caribbean hurricanes or Asian monsoons.

Yes, all CIF shipments are covered by comprehensive marine insurance, protecting your chemical investment against the risks of trans-oceanic transit, rough seas, and port handling.

We handle the sea freight directly to your destination port. Once the containers are unloaded, the responsibility is passed cleanly to the buyer's localized logistics agents to manage customs clearance and inland trucking.

Yes, all wooden packaging utilized for AuCyan™ exports undergoes strict IPPC-certified fumigation and is stamped accordingly to comply with global agricultural and customs regulations.

We provide a complete suite of export documentation, including the Commercial Invoice, Packing List, Bill of Lading (B/L), Certificate of Origin (CO), and the comprehensive Material Safety Data Sheet (MSDS).

Due to stringent International Maritime Dangerous Goods (IMDG) codes regarding the segregation of hazardous and non-hazardous materials, AuCyan™ (Class 6.1) and AuCarb™ must be shipped in dedicated, separate containers.

If AuCyan™ mixes with water, it hydrolyzes. If it mixes with acids, it immediately releases highly toxic, lethal Hydrogen Cyanide (HCN) gas. It must be stored in a dry, strictly alkaline environment at all times.

Operators must wear full Personal Protective Equipment (PPE) including chemical-resistant gloves, full-face respirators equipped with specific cyanide gas cartridges, splash-proof goggles, and rubber boots.

Do not use water. Dry spills should be carefully swept up and placed into sealed containers. Any contaminated surfaces must be neutralized using a strong alkaline oxidizing solution (like sodium hypochlorite) while personnel wear full respirators.

Because AuLeach™ is non-hazardous and degrades naturally into non-toxic compounds, it requires minimal to zero specialized chemical detoxification before being discharged to the tailings dam, drastically reducing environmental liabilities.

Yes, our manufacturing facilities operate under strict יסאָ קסנומקס (קוואַליטעט פאַרוואַלטונג) און יסאָ קסנומקס (Environmental Management) certifications, ensuring global-grade consistency and safety.

Absolutely. Community protests often stem from the fear of toxic cyanide spills contaminating local water supplies. Implementing the non-toxic AuLeach™ physically eliminates this threat, serving as a powerful PR and community relations tool.

The INCO SO2/Air process is a common method to detoxify cyanide tailings. It utilizes sulfur dioxide and oxygen, catalyzed by copper, to oxidize toxic free cyanide into relatively harmless cyanate. (Note: Using AuLeach™ eliminates the need for this expensive process).

Storage facilities must be elevated, flood-proof, well-ventilated, and completely shielded from direct sunlight and rain. Acids and other reactive chemicals must be strictly quarantined in entirely separate buildings.

In case of inhalation or ingestion, move the victim to fresh air immediately and seek emergency medical attention. Cyanide antidote kits (such as Amyl Nitrite, Sodium Nitrite, and Sodium Thiosulfate) must be kept on-site and administered by trained professionals.

No. While basic dust masks should be worn during transfer, AuCarb™ is non-toxic and features an ultra-low attrition rate, minimizing the generation of airborne carbon dust in the plant environment.

Yes, the steel drums can be neutralized and recycled, and the robust wooden boxes can be repurposed safely on-site. The inner PE bags should be handled according to local hazardous waste protocols if they contained cyanide.
