Processing, smelting and refining gold World Gold

2021-7-8  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

Leaching and recovery of gold from ore in cyanide

2020-11-1  This assumption was supported by observing 72% extraction of gold from ore into the solution in the CIL-1 test, while longer retention time (36 h) enhanced the dissolution of gold to 83% (CIL-2). Fleming et al. (2011) also demonstrated that in a CIP plant, all the leachable gold is already present in solution before the first carbon adsorption tank providing substantial kinetic driving force for adsorption.

How Is Gold Processed? Reference

2020-3-29  Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
