Abstract:
A process for recovery of gold from gold-containing raw materials includes obtaining gold-containing raw material having refractory gold-containing sulfidic minerals including a first type of refractory sulfidic mineral having high gold content and a second type of sulfidic mineral having low gold content; forming a mineral pulp including a first type of refractory sulfidic mineral particles having high gold content and second type of sulfidic mineral particles having low gold content by suspending ground gold-containing material in water and optionally further milling the material; conditioning the mineral pulp by addition of a surface modifying chemical to obtain a conditioned pulp; subjecting the conditioned pulp to a froth flotation process; recovering the non-floatable first type of refractory sulfidic mineral particles having high cold content as flotation tailings; pressure oxidizing (PDX) the flotation tailings to obtain a discharge slurry comprising liberated gold; and recovering gold from the discharge slurry.

Claim (Index 3):
The process as claimed in  claim 1 , wherein the refractory gold-containing material comprises gold locking or cyanide consuming materials, particularly sulfidic minerals such as iron sulfides, arsenic sulfides, copper sulfides, antimony sulfides, tellurides, elemental sulfur, or any mixture thereof.
