PROCESSING: Heap leaching – The ore is crushed or placed directly on lined leach pads where a weak cyanide solution is applied to the surface of the heap. The solution percolates down through the ore, where it leaches the gold and flows to a central collection location.

Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or ...

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.

Location. Florida. Jul 25, 2008. #8. The flow chart is a good start but needs some fine tuning. Here's some of the quick things I saw: * I noticed it doesn't include the inner bucket strainer idea. This is critical to good agitation and ease in separating the foils from the solution. * No mention is made of testing for gold in the solution.

Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.
