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 1):
A process for recovery of gold from gold-containing raw materials comprising refractory gold-containing minerals, in particular gold-containing refractory sulfidic minerals, comprising:\n (a) obtaining gold-containing raw material comprising refractory gold-containing sulfidic minerals comprising first type of refractory sulfidic mineral having high gold content and second type of sulfidic mineral having low gold content, said first type and said second type of sulfidic minerals are to be classified within a single species of refractory sulfidic minerals; (b) forming a mineral pulp comprising 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; (c) conditioning the mineral pulp by addition of a surface modifying chemical for modifying the surface of the first type of refractory sulfidic mineral particles having high content thus making the said particles non-floatable to obtain a conditioned pulp; (d) subjecting the conditioned pulp to a froth flotation process to separate first type of refractory sulfidic mineral particles having high gold content from the second type of sulfidic mineral particles having low gold content; (e) recovering the non-floatable first type of refractory sulfidic mineral particles having high gold content as flotation tailings; (f) pressure oxidizing (PDX) the flotation tailings recovered in step (e) to obtain a discharge slurry comprising liberated gold; and (g) recovering gold from the discharge slurry obtained in step (f).
