Leaching gold with cyanide is the most common method of gold recovery from ores and requires precise electrochemical control of a number of reagents. Alkaline environments are a must for safety; incorrect pH control can cause over-use of reagents and create highly dangerous process environments with the evolution of Hydrogen Cyanide.
Cyanide Leaching Of Gold, Laboratory Bottle Tests
Gold Cyanide Solution, Laboratory Bottle Test Method This is one method for doing cyanide bottle leaching tests for determining the 'leachability' of gold and silver by leaching with cyanide. Take the ore to be leached and crush it to a size that will fit into a pulverizer (usually -1/4"). Then feed the ore to a pulverizer and grind to -100 mesh.
PREPARATION OF NON-CYANIDE ELECTROLYTE FOR GOLD .PREPARATION OF NON-CYANIDE ELECTROLYTE FOR GOLD PLATING Silvana B. Dimitrijevic, Institute of mining and metallurgy, Zeleni bulevar 35, 19210 ... A/dm2, without additives, pH= 9-12 and t= 230C. Macrophot of gold plated plate at optimum parameters of electrolysis is shown in Figure 2. Peroxides Metals and Mining Solutions - SolvayOur Mining Solutions Gold and Silver Leaching. Solvay's Hydrogen Peroxide INTEROXⓇ Standard Grade is used in gold and silver leaching processes to enhance overall leach recovery and optimise cyanide consumption. The use of Peroxide technology increases the rate of leaching through enhancing the delivery of oxidant in solution and through partial oxidation of associated minerals.

Waihi Gold, New Zealand ...that cyanide can be transported, stored, used and disposed of in a safe manner, with no significant adverse effects on the environment. Cyanide is used in the electroplating industries, the tanning industry and in specialised laboratories. Sodium cyanide is also used in New Zealand to produce a cyanide paste for opossum control.

Introduction. Santo António gold mines are situated in the North of Portugal and were already explored in the 1st century A.D. by the Romans. These mines were reactivated around 1950 and closed 10 years later.Standard Test Method for Aquatic Free Cyanide .1. Scope. 1.1 This test method is used to establish the concentration of aquatic "free" cyanide in an aqueous wastewater or effluent. The test conditions of this method are used to measure free cyanide (HCN and CN-) and cyanide bound in the metal-cyanide complexes that are easily dissociated into free cyanide ions at the pH of the aquatic environment ranging from pH 6 to pH 8.
