If excessive sodium cyanide or air is added during the leaching process, it will not increase the leaching rate of gold and cause waste. Therefore, in the gold leaching process, it is often necessary to analyze and control the free cyanide and the oxygen content in the solution to keep the ratio of the two at about 6.

Use Cases for Gold Plating in Electronics. You can find gold in all sorts of electronics including smartphones, laptops and desktop computers. One ton of smartphones, or about 10,000 phones, contains approximately 10 troy ounces of gold, which is equal to around three fifths of a pound.From 200 laptops, you could get about five troy ounces of gold, which is worth roughly 8000.
The Metallurgy of Cyanide Gold Leaching An Introduction . Coreresources.com.au DA 24 PA 50 MOZ Rank 75. Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
At present leaching of gold-containing raw materials by cyanide is the main hydrometallurgical process and the main advantage of cyanide is high selectivity with regard to gold. However, leaching by cyanide solutions has a set of substantial drawbacks process duration, high cost of
