بيت /luvial gold leaching process
remove the gold cyanide, and the gold metal is produced using a process called electrowinning. Due to the rapid reactions taking place in an agitated leach process, automatic pH control is strongly recommended. pH is controlled between 11 and 12 during the leaching process. pH values below 11 favor the formation of HCN, hydrogen cyanide

Mar 03, 2011· Alluvial is a term that refers to soil sediments and the various sand, silt, gravel, clay or other deposited matter left behind by flowing water. "Alluvial gold" refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold. Panning for gold is one of the oldest ways to produce gold.

How to Leach Gold Ore With Chlorination ... Aerating the mixture speeds up the leaching process, because it adds oxygen. Continue to agitate the bucket until the ORP meter drops to 400. Keep the ORP meter around 1,000, but do not let it drop below 400. The HCL is a chemical that steals electrons from the substances it is mixed with.
