Kiimikooyinka CIP/CIL & Heap Leach ee Sare ee Waaxda Macdanta Dahabka ee Zimbabwe

Zimbabwe waxay leedahay dhaxal macdan qodis oo qani ah, iyadoo kayd dahab ah oo aad u badan uu ku urursan yahay Greenstone Belts iyo gobolka Great Dyke. Warshadaha warshadaynta ee ka shaqeeya xarumaha waaweyn sida Gwanda, Kadoma, iyo Kwekwe waxay u baahan yihiin walxo bir ah oo saafi ah oo saafi ah oo bixiya heer soo kabasho oo joogto ah oo ka yimaada jirka macdanta sulfide-ka ee oksaydhka leh iyo kuwa adag.

United Chemical waa lammaane caalami ah oo lagu kalsoon yahay oo loogu talagalay soo saarayaasha dahabka Zimbabwe. Waxaan bixinaa faylal isku dhafan oo ah walxaha daadinta ee heerka caalamiga ah waxaana la hawlgeliyaa Carbon, oo lagu bixiyo shuruudo ganacsi oo caalami ah oo dabacsan ( Dekedaha FOB ee Shiinaha iyo Dekedaha badweynta gobolka ee CIF ) si loo hubiyo gaarsiinta caalamiga ah oo aan kala go 'lahayn oo waafaqsan shuruudaha.

Wakiiladayada calanka ee Wareegyada Dahabka ee Zimbabwe

1. AuCyan™ NaCN Sodium Cyanide ≥ 98.3%

Waxaa loo farsameeyay hawlgallada CIL (Kaarboon-ku-jira-Leach) iyo CIP (Kaarboon-ku-jira-Pulp) ee joogtada ah ee u baahan isku-dheellitirnaan aan kala go 'lahayn, AuCyan™ NaCN Sodium Cyanide ≥ 98.3% waxay bixisaa nadiifnimo sare oo leh wasakh yar oo aan milmi karin. Waxay dammaanad qaadaysaa kinetics-ka daadinta degdegga ah, taasoo u oggolaanaysa khubarada birta dhirta ee Zimbabwe inay wanaajiyaan isticmaalka reagent-ka oo ay ilaaliyaan soo kabashada dahabka ee joogtada ah xitaa marka ay maareynayaan heerarka kala duwan ee macdanta.

2. Kaarboonka Qumbaha ee Dahabka ah ee AuCarb™ ee la Firfircooday

Taangiyada CIL/CIP ee kacsan ee sare, xoogagga xiirashada farsamada ayaa jebin kara kaarboon heer hoose ah, taasoo keenta khasaare dahab ah oo daran oo ku yimaada dabada. Kaarboonka firfircoon ee AuCarb™ Gold Recovery Coconut Shell Activated Carbon ayaa la sameeyay si looga hortago tan, iyadoo leh adkeysi kubad-digsi oo si madax-bannaan loo xaqiijiyay oo ah ≥ 99% . Iska caabbinta soo-baxa ee sareysa waxay hubineysaa in dahabka la nuugay uu si ammaan ah ugu xirnaado daloolada kaarboonka iyada oo loo marayo wareegyo nuugid iyo qulqul badan.

3. Wakiilka Dahabka ee AuLeach™ ee Deegaanka u roon (GDA)

Iyadoo xeerarka macdan qodista Afrika ay u socdaan maamul deegaan oo adag, AuLeach™ Eco-Friendly Gold Leaching Agent (GDA) waxay bixisaa beddel waara. Beddelka aan khatarta ahayn ee cyanide -ka caadiga ah , AuLeach™ waxay bixisaa kinetics leaching siman ama dhakhso leh iyadoo si buuxda u baabi'inaysa sunta cyanide ee ka timaadda dabada, fududeynaysa hubinta deegaanka iyo u hoggaansanaanta gaadiidka maxalliga ah.

Shuruudaha Maraakiibta Caalamiga ah iyo Ganacsiga ee Dabacsan (FOB & CIF)

Si loo waafajiyo siyaasadaha caalamiga ah ee wax iibsiga ee shirkadaha macdanta Zimbabwe iyo qabanqaabada saadka ee maxalliga ah, United Chemical waxay bixisaa Incoterms dabacsan oo heer sare ah:

• FOB (Lacag La'aan ah - Dekedaha Shiinaha ee ugu Muhiimsan): Waxaan maamulnaa dhammaan saadka gudaha, nadiifinta dhoofinta, kormeerka Alaabta Khatarta ah (DG), iyo rarista maraakiibta konteenarrada ee loo qoondeeyay dekedaha waaweyn ee Shiinaha (tusaale ahaan, Shanghai, Ningbo, Qin GDA o).

• CIF (Kharashka, Caymiska & Xamuulka - Dekedaha Albaabka Gobolka): Waxaan si toos ah u maamulnaa caymiska maraakiibta badda iyo gaadiidka ee dekedaha badda ee albaabka koowaad ee u adeega Zimbabwe, oo ay ku jiraan Dekedda Beira (Mozambique) iyo Dekedda Durban (Koonfur Afrika).

• Baakadaha Badda ee u hoggaansan: AuCyan™ NaCN Sodium Cyanide ≥ 98.3% waxaa loo soo diraa si adag iyadoo la raacayo xeerarka IMDG (Alaabta Khatarta ah ee Badda Caalamiga ah) iyadoo la adeegsanayo durbaanno bir ah oo UN-ka shahaado siisay ama sanduuqyo alwaax ah oo culus oo ku jira weelal xiran. AuCarb™ iyo AuLeach™ oo aan khatar ahayn waxaa lagu soo diraa bacaha qoyaanka u adkaysta ee culus.

Su'aalaha Badiya La Weydiiyo

S1: Shuruudaha ganacsi ee ay sameeyaan (Incoterms) United Chemical Dalab shixnadaha loogu dirayo Zimbabwe?

Waxaan bixinaa shuruudo dabacsan oo FOB ah (Bilaash ah oo ku yaal Guddiga) laga bilaabo dekedaha waaweyn ee Shiinaha iyo shuruudaha CIF (Kharashka, Caymiska, iyo Xamuulka) ee dekedaha gobolka ee u adeega Zimbabwe, sida Dekedda Beira (Mozambique) ama Dekedda Durban (Koonfur Afrika) . Tani waxay u oggolaanaysaa iibsadayaasha inay isku dubbaridaan gaadiidka gudaha ee maxalliga ah laga bilaabo dekedda ilaa goobta macdanta iyagoo u eegaya doorbidkooda.

S2: Maxay muhiim u tahay adkeysiga Kaarboonka Firfircoon ee ≥ 99% warshadaha CIL ee Zimbabwe?

Taangiyada firfircoon ee ka shaqeeya macdanta xoqidda ee ka timaadda Greenstone Belts, kaarboon jilicsan ayaa isu beddela walxo yaryar oo si toos ah u qaada dahabka la nuugay ee dabada. Kaarboonka firfircoon ee AuCarb™ Gold Recovery Coconut Shell wuxuu bixiyaa adkaansho la tijaabiyay oo ah ≥ 99% , taasoo bixisa iska caabin farsamo oo ugu badan si looga hortago burburka kaarboonka loona ilaaliyo wax soo saarkaaga dahabka.

S3: Sidee baa AuCyan™ NaCN Sodium Cyanide ≥ 98.3% baakad loogu xidhaa badbaadada xamuulka badda?

Dhoofinta badda ee hoos timaada xeerarka IMDG, AuCyan™ NaCN Sodium Cyanide ≥ 98.3% waxaa lagu shubaa durbaanno bir ah oo si hermetically ah loo shaabadeeyey oo ay Qaramada Midoobay ansixisay ama sanduuqyo alwaax ah oo culus oo leh bacaha gudaha ee polyethylene. Shixnad kasta waxaa ku jira MSDS buuxa, Shahaadada Falanqaynta (COA), iyo dukumentiyada alaabada khatarta ah ee looga baahan yahay gaadiidka badda ee caalamiga ah iyo nadiifinta kastamka dekedaha.
