Gold Recovery And How To Choose The Right Process

Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade. Low grade free-milling gold deposits contain less than 1 g/t of gold. This low grade ore is crushed and heap leached to recover the gold. While heap leach recoveries are lower than in

Method for recovering gold, platinum or silver from

A method of recovering gold from an ore containing micron gold or gold dust is disclosed. The gold is recovered by providing a silver coated surface, coating the silver coated surface with mercury, washing a mixture of ore and water over the mercury such that an amalgam of gold and mercury is created on the silver coated surface, removing the amalgam from the silver coated surface, and heating

How to Use Bleach on Gold Ore to Remove Gold

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

RECOVERY OF GOLD FROM CARBONACEOUS ORES

An ore containing 0.23 oz./ton gold, and 0.97 percent total carbon including 0.35 percent organic carbon was contacted with a synthetic solution of Au(CN)-2 having a concentration of 11.1 g./l. for 2 hours. Upon assay it determined that the ore had absorbed 12.5 oz. of gold per ton of ore. EXAMPLE II

Heap Mining Efficiently Leaches Lower Grade Gold

At a 75% gold recovery, it takes 41 tons of ore on the pad to recover one ounce of gold. However, all the material in the mine is not ore. Most mines will have 2-3 tons of waste material to 1 ton of ore. This waste must be taken to a separate dump. This is called the “strip ratio” and is a very important aspect in developing and operating a
