The object of the invention is to regenerate the reagent bound as copper and similar soluble heavy metal complexes absorbed by an ion exchange resin, and return the regenerated and the free in the column effluent for reutilization to the . The novel for recovering reagents from effluent solutions ...

-zinc replacement CCD method and CCF method back to top. The working principle of -zinc replacement is to use zinc powder silk as the reducing agent to replace gold and silver from the leaching liquid, which mainly includes four operations: washing solid-liquid separation, purification, deoxidation,replacement.

Here I present an EXAMPLE of Gold Extraction in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7% ...

Cyanidation ---carbon adsorption is the most widely used in gold extraction . The principle in brief is the carbon could adsorb liquid gold from solution . In 1970s , with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold , make recycle the carbon and reduce the cost , and easy to the gold ...
