Gold Cyanide Leaching Process liming Outotec

Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.

Natural Source of Cyanide in Plants eHow

Many common plants contain the natural form of cyanide, cyanic glucoside. Its presence may be the product of evolution, as it deters animals and insects from consuming the entire plant. Most animals can tolerate digesting small amounts, but during drought, the amont of the chemical in plants increases.

Healing Plants with Cyanide Mother Earth Living

These plants, along with almost 2,000 more, contain phytochemicals called “cyanogenic glycosides.” Cyanogenic glycosides have a chemical structure that contains one carbon with a cyanide group linked to a sugar (“glyco” means sugar). During digestion, the cyanide group is

How to Reduce Sodium Cyanide Consumption of Gold

Copper consumes a large proportion of cyanide in the leaching process. For example, a gold cyanidation plant has a copper grade of 0.548% in raw ore, and the mother liquor of the first leaching contains 1161mg/L copper, which consumes 37.6% of the annual cyanide consumption.
