Apr 14, 2015 Refining in this case is with reference to removing impurities at a micron and sub micron level. The process of recovery is a process that continually upgrades the purity through a process of concentration. A sluice box recovers gold as a concentrate which has greater gold content. Recovery is a process of eliminating non gold products from gold.

I claim 1. A method for extracting gold from ore comprising contacting ground ore having interstitial gold with a chemical solution including at least two species of chemicals, where a first species is an alkali alkaline halide where said alkali alkaline portion of said first species is selected from the group consisting essentially of potassium, sodium, barium, and calcium, and wherein said.

Briefly, gold is extracted from the ore and dissolved in the chemical solution to form a gold complex. Next, the complex is reduced to gold from the solution, preferably by one of two methods. The first method precipitates the gold complex by washing and decomposing of the gold complex to form pure gold.

Smelting is an integral part of the refining process of gold and other precious metals. It is the major part of refining where the precious metal (gold in this case) is melted out of its ore. Metal ores often contain a lot of other elements and impurities, smelting is therefore important in removing these.
