Processing Gold Ores Using Heap Leach Carbon Adsorption Methods
preferred method for recovering the precious metal values from heap leach effluents is by adsorption on activated carbon. Not only is the carbon adsorption process more efficient than zinc precipitation for treating dilute gold silver cyanide solutions, but the method also entails lower capital and operating costs (5 5, 24).
Cyanide Leaching Of Gold Mine Engineer
There has also been a lot of experimentation with various biological media for recovering gold from ores, but no one has come up with a more cost effective and productive method than leaching with cyanide. In some special circumstances, some of the other methods may show promise, but for a good oxide gold ore, CN.Get Price
