Cov thev naus laus zis tseem ceeb rau Kev Pov Hwm Tsis Muaj Teeb Meem ntawm Kub Concentrate Cyanide Residue

Cov txheej txheem cyanidation rau kev rho tawm kub, muaj keeb kwm ntau tshaj 100 xyoo, tseem muaj nyob hauv kev tsim khoom kub tam sim no. Nws qhov nrov yog vim nws yooj yim thiab tus nqi rov qab tau kub siab. Txawm li cas los xij, cov txheej txheem no tsim tau ntau cov tailings kub. Cov zis ntawm cyanide residues los ntawm cov kub concentrates tau nce txhua xyoo. Cov ntaub ntawv qhia tias lub teb chaws kev lag luam kub tsim tawm kwv yees li 80 lab txog 100 lab tons ntawm cyanide residues txhua xyoo.

Kev khaws cov cyanide residues no mus ntev ua rau muaj ntau yam teeb meem. Ua ntej, nws siv thaj av loj heev. Qhov thib ob, cov cyanides lom heev hauv cov residues tuaj yeem tso cov pa lom thiab tsim cov dej khib nyiab acidic. Tsis tas li ntawd, ntau yam hlau ions tuaj yeem ua rau cov dej thiab av nyob ib puag ncig puas tsuaj los ntawm dej saum npoo av lossis dej hauv av, ua rau tib neeg muaj kev noj qab haus huv txaus ntshai. Qhov txawv txav yog tias cov cyanide residues los ntawm cov kub concentrates muaj cov khoom muaj nqis xws li Cu, Pb, Zn, Fe, Au, S, thiab Si uas tseem tsis tau rov qab los. Yog li, kev sib cais cov khoom muaj nqis kom zoo, kev sib cais thiab rov qab los ntawm cov khoom muaj nqis, thiab kev siv cov de-cyanided tailings loj tau dhau los ua qhov tseem ceeb thiab kev cov nyom thoob ntiaj teb.

United Chemical Co., Ltd.'s Solution: A Holistic Project

Teb rau cov kev cov nyom no, United Chemical Co., Ltd. pib qhov "Kev Tshawb Fawb thiab Kev Siv Cov Cuab Yeej Tseem Ceeb rau Kev Pov Hwm Tsis Muaj Teeb Meem thiab Kev Siv Khoom Siv Cyanide Residues los ntawm Kub Concentrates" project.

Gradient - Tswj De - cyanidation thiab Flotation rov qab

Lub "Tshiab Technology rau Gradient - Tswj De - cyanidation thiab Flotation rov qab ntawm cov khoom tseem ceeb" tau txais kev pom zoo kom rov qab tau Cu, Pb, thiab Zn los ntawm kub cyanidation tailings. Yog li ntawd, lead concentrates thiab tooj liab concentrates tau tsim.

Pyrite Interface Activation thiab Combined Processing rau Hlau thiab Kub Rov Qab

Tom ntej no, "Tshiab Technology rau Pyrite Interface Activation thiab Combined Mineral Processing thiab Metallurgy rau Hlau thiab Kub Rov Qab" tau siv. Cov tshuab no tau zoo sib cais thiab rov qab tau Fe thiab Si los ntawm de - cyanidated flotation tailings, yielding sulfur concentrates thiab siab - silicon tailings.

Sulfuric Acid thiab Hlau Pellet Production

Sulfur concentrates tau siv los tsim cov concentrated sulfuric acid los ntawm qaug zog - oxygen roasting. Cov roasted sulfur slag tau pelletized. Tom qab ntawd, "High - Temperature Iron - Kub Separation Technology" tau siv los tsim cov hlau pellets thiab kub av nkos nrog Cu, Pb, thiab Zn.

High - Silicon Tailings Recycling

Lub "Tsev Kawm Ntawv Tshiab rau Theem - Hloov Txoj Cai thiab Tag Nrho - Cov Khoom Siv Rov Ua Dua Tshiab ntawm High - Silicon Tailings" tau ua rau kev hloov pauv ntawm siab - silicon tailings rau hauv European - style interlocking ceramic vuas.

Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb

Qhov phiaj xwm no tau daws qhov "plaub qhov teeb meem" cuam tshuam nrog cyanide residues los ntawm cov kub concentrates: kom nkag siab txog cov tshuaj lom neeg, tswj thiab tswj xyuas lawv tus cwj pwm, rov ua kom muaj txiaj ntsig zoo, thiab rov ua dua tailings. Nws tau qhia txog kev sib koom ua ke tshiab, kev sib koom ua ke ntawm cov ntxhia ua, metallurgy, thiab kev tshawb fawb ib puag ncig. Cov kev tshawb fawb tau nthuav tawm tag nrho cov kev lag luam tshiab, los ntawm kev nthuav tawm cov laj thawj rau kev tsim cov thev naus laus zis thiab kev ua qauv qhia engineering.

Nyob rau hauv kev tshawb fawb thiab thev naus laus zis, nws tau qhia txog qhov tshwm sim ntawm cov khoom siv tshuaj lom hauv cyanide - muaj cov pov tseg uas muaj kev phom sij heev. Nyob rau hauv daim ntawv thov, nws tsim technologies rau kev ruaj ntseg dissociation thiab ruaj khov pov tseg ntawm cov tshuaj lom Cheebtsam, kev sib koom tes extraction ntawm cov khoom tseem ceeb, thiab kev siv cov khoom siv tailings siab.

Txaus siab rau Industrial Application Results

Tom qab siv cov kev ua tiav ntawm qhov project no rau kev lag luam, tus nqi rov qab tau cov hlau muaj nqis los ntawm cov cyanide residues ntawm cov kub concentrates tau tshaj 90%. Qhov kev ua tiav no tau ua rau muaj kev pov tseg tsis muaj kev phom sij thiab kev siv tag nrho cov khoom siv cyanide residues los ntawm cov kub concentrates. Txhua xyoo, qhov project tsim tau kwv yees li 8.000 tons ntawm cov lead concentrates thiab cov tooj liab concentrates, ntau tshaj 300.000 tons ntawm cov high-sulfur concentrates, ntau tshaj 200.000 tons ntawm concentrated sulfuric acid thiab oxidized pellets, kwv yees li 700 kg ntawm kub, thiab ntau tshaj 90 lab European-style interlocking vuas. Pom tseeb, qhov project tau coj los txog kev lag luam, ib puag ncig, thiab kev sib raug zoo.
