Processing, smelting and refining gold World Gold

2 天前  For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining

Process for recovering gold from refractory sulfidic

A process for recovering gold from a refractory sulfidic ore which has been suspended in an aqueous slurry and oxidized using nitric acid so that substantially all of the gold in the ore is made available for recovery and at least a portion of the sulfidic components present during the oxidation are oxidized to elemental sulfur, comprises bubbling air as a discontinuous phase upwardly through ...

Recovering Gold from Copper Concentrate via the ...

2016-9-29  The most widespread method of producing copper is the smelting of copper sulfi de concentrates. An alternate method that is growing in popularity is heap leaching of oxidized copper ores with weak sulfuric acid together with copper solvent extraction and electrowinning (EW). Now approaching a 20% share of primary copper produc-tion, heap leaching offers reduced costs compared with the costs of smelting and refining. Those savings result from the omission of energy-intensive ore grinding and flotation. Limited resources of oxidized copper ores, the long leaching time of chalcopyrite, and an inability to recover gold
