Greengold | THE RECYN PROCESS

The process is based on the use of a functionalized resin bead, pre-treated to allow the dual duty of recovering free and complexed cyanide ions from solution with a high degree of efficiency. The GGT Treatment Plant is custom designed for each operation to match the various solution chemistries and throughputs. The two areas of cyanide recovery and metal detoxification are balanced to achieve

Gold Cyanidation Process

The Cyanidation Process or CYANIDE LEACHING is ‘most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated. But

MODELING OF GOLD CYANIDATION

The chemistry of gold dissolution in alkaline cyanide solution has continually received attention and new rate equations expressing the gold leaching are still developed. The effect of leaching parameters on gold cyanidation is studied in this work in order to optimize the leaching process. A gold leaching model, based on the well-known shrinking-core model, is presented in this work. It is

This shows that the impact of particle diameter on the CIL process is prominent. For the highest cyanide concentration studied (700 mg/l), although the improvement in percent recovery was 1.9% as compared to the maximum of 2.5%, but the recovery was also much higher. The rate of decrease in cyanide concentration is dependent on particle diameter. The rate of consumption of cyanide decreases

Cyanide Use in Gold Mining Earthworks

Cyanide is a rapidly acting, potentially deadly chemical. “Cyanide” can mean any one of various compounds containing the chemical group CN: one atom of carbon (C) and one atom of nitrogen (N). Because it is organic, it reacts readily with living organisms. Cyanide easily combines with many metals – making it useful in separating metals like gold from their ore. How is cyanide used in
