non cyanide gold stripping solution

non cyanide gold stripping solution

Agitation: None to vigorous solution movement Stripping Rate: 1–3 microns (40–120 microinches) per minute When stripping gold from nickel and ferrous alloy base metals, the stripping rate can substantially be increased by increasing the potassium cyanide content to 22.5–37.5 g/l (3–5 oz./gal.). This formulation adjustment is not

EDXRF elemental analysis method for gold in stripping

Dec 28, 2015 The cyanide leaching technique is commonly used to recover trace gold content from gold-bearing ores. Once the gold is leached from the ore, it is typically absorbed onto activated carbon and then stripped. The impregnated stripping solution is then put into the EW process where the gold is recovered by electrolysis.

Cyanide Solution an overview ScienceDirect Topics

Gold is stripped from carbon by passing a caustic cyanide solution preheated to 90 C through two or more high stripping columns containing loaded carbon on a batch process. The carbon is treated with dilute hydrochloric acid in the working column to remove carbonates that may build up due to the addition of lime to the leach circuit.
