The cyanidation process accounted for 80-90% of all gold recovered by the gold mining industry from primary resources in the 20th century. The advantages of the process are its relative simplicity, its chemical and physical durability, its relatively low cost, and the generally very high recoveries of gold (and silver), that are achieved.

May 15, 2017 Silver has long been recognised to enhance the bioleaching of chalcopyrite, and has in the past been added to facilitate this process (e.g. Romero et al., 2003). Copper concentrates sometimes contain sufficient silver to catalyse the oxidative dissolution of chalcopyrite, even at relatively low temperatures (Johnson et al., 2008).

MINING METHOD. Red Dog is an open-pit mine using conventional truck-and-shovel methods with special provisions for operating in the Arctic climate. High grades, low stripping ratio (0.81) and short haul distances result in the low mining rate of 10,000t/d. Bench heights are 7.6m and pit slopes vary depending on wall material.
Processing Plant Flowsheet Design. The foundation for superior process design is sound ore deposit knowledge and comprehensive testwork. Our metallurgists are experienced in designing and supervising comprehensive test programs for both greenfield and existing operations. Based on analysis of the test results, we work closely with in-house ...
