FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES OVERVIEW There are several basic metallurgical flowsheets used to treat gold orebodies, with a great many permutations. The amenability of an ore to the cyanidation process are gold leach efficiency and cyanide consumption as a function of the fineness of grind and other leach conditions.

Development of a flowsheet incorporating cyanidation, CIP

A flowsheet has been developed to treat the flotation tailings from a copper mine in Mexico to recover gold and silver by cyanidation and carbon-in-pulp (CIP). The plant will treat ~15,000 t/day of a 60:40 blend of current flotation tailings and the mine’s historic tailings.

Cyanide Process Gold Cyanidation Process Gold Leaching

Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.
