This alternative leaching solution is unique in its versatility and scalability—capable of being applied to a wide range of goldbearing ores encountered by different operators Nontoxic, nonflammable and water soluble, the gold recovery agent’s success rate in leaching gold from certain ores—eg carbonaceous—is 50% more compared toCNLITE ecofriendly gold leaching reagent can 100% take place of sodium cyanide for gold processing and refining, including gold CIP, CIL, heap leaching, pool leaching and other cyanide process Different with cyanide, it is lowtoxicity, environmentalfriendly andCNLITE Ecofriendly Gold Leaching Reagent
The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydrometallurgically The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolveThe latest breaking news, comment and features from The Independent Zimbabwe holds burial for 3 top leaders who died of COVID19 News 23 gold miners feared dead after dam bursts inHarare latest news, breaking stories and comment The
