Kev Paub Txog Kev Tshem Tawm Kub Deep-Level & Refractory hauv South Africa: Kev daws teeb meem Reagent Advanced
South Africa yog lub tebchaws keeb kwm ntawm kev khawb kub niaj hnub no. Muaj cov chaw tsim khoom geological xws li Witwatersrand Basin - lub tsev rau lub ntiaj teb cov haujlwm hauv av tob tshaj plaws xws li Harmony Gold's Mponeng Mine , Gold Fields' South Deep Mine , thiab Sibanye-Stillwater's Driefontein operations - nrog rau cov chaw pyritic ultra-refractory ntawm Barberton Greenstone Belt (Pan African Resources' Fairview thiab Sheba mines). Txawm li cas los xij, kev rho tawm kub los ntawm cov pob zeb tob no thiab cov pob zeb nyuaj ua rau muaj kev cov nyom tsis tau muaj dua rau cov thawj coj cog khoom niaj hnub no thiab cov kws tshawb fawb txog hlau.
Hauv cov nroj tsuag metallurgical South Africa niaj hnub no, kev ua haujlwm zoo raug hem los ntawm peb qhov teeb meem tseem ceeb. Ua ntej, Highly Refractory & Pyritic Ore Matrices: Cov pob zeb rho tawm los ntawm cov Carbon Leader tob thiab Ventersdorp Contact Reefs (VCR) lossis Barberton quartz- Carbonate veins raug kaw nruj nreem hauv pyrite thiab arsenopyrite matrices. Cov zaub mov sulfide no siv cov cyanide dawb thiab oxygen, ua rau qeeb qeeb leaching kinetics thiab txo qis tag nrho cov kub rov qab. Qhov thib ob, Hnyav Carbon Attrition & Preg-Robbing: Cov nroj tsuag Carbon-in-Pulp (CIP) thiab Carbon-in-Leach (CIL) muaj peev xwm siab siv cov khoom siv loj, siab-shear. Soft Activated Carbon sai sai tawg ua hmoov av zoo hauv qab lub zog shear hnyav no, nqa cov kub adsorbed ncaj qha mus rau hauv Tailings Storage Facilities (TSF). Ntxiv mus, cov txheej txheem carbonaceous shale ntuj hauv cov pob zeb ua haujlwm "preg-rob" yaj kub los ntawm cov kua. Qhov thib peb, Kev Saib Xyuas Ib Puag Ncig Nruj (DWS & NEMA): Lub Tsev Haujlwm Saib Xyuas Dej thiab Kev Ua Kom Huv Si ntawm South Africa (DWS) thiab Txoj Cai Tswj Xyuas Ib Puag Ncig Hauv Tebchaws (NEMA) tswj hwm cov kev txwv tsis pub muaj cyanide thiab cov hlau hnyav hauv cov pas dej tailings kom tiv thaiv Acid Mine Drainage (AMD) thiab kev ua qias tuaj hauv av.
United Chemical xa cov tshuaj lom neeg uas ua tau zoo thiab tau lees paub hauv daim teb uas tshwj xeeb rau cov chaw cog kub tob thiab kub tsis kam hauv South Africa. Los ntawm kev sib xyaw cov tshuaj lixiviants uas muaj kev ntshiab siab, ua rau nws ruaj khov heev. Txiv maj phaub plhaub cov pa roj carbon, thiab cov tshuaj leaching uas tsis muaj kev phom sij rau ib puag ncig, peb txhawb nqa cov neeg ua haujlwm hauv South Africa kom ua kom rov zoo tshaj plaws, tshem tawm cov pa roj carbon, thiab tswj hwm kev ua raws li ib puag ncig tag nrho.
