Effect of Copper on Leaching of Pure Gold. Metallurgists have long investigated the effect of copper in cyanide solutions on the leaching of pure gold and on the extraction of gold from ores. In their tests on pure gold, they prepared cyanide solutions containing copper by dissolving relatively pure cuprous cyanide, CuCN, in sodium cyanide.

Effect of Leaching on Permeability of Copper Ores
Effect of Leaching on Permeability of Copper Ores

As leaching progresses and the copper in the specimen is depleted, the amount of copper recovered per day of leaching decreases. There is a definite increase in permeability as leaching progresses. This is primarily due to the dissolution of copper mineral(s) along the fractures, thus widening the fracture aperture.

What Are the Effects of Leaching? Sciencing
What Are the Effects of Leaching? Sciencing

When leaching removes too much nitrate content from the soil, however, the pH drops too far and the soil become overacidic. Soil acidification yields numerous negative consequences in itself, including alteration to the types of soil microbes, surface water contamination and declining populations of earthworms.
