Mineralogy of Gold Ores. The manner of gold occurrence and its association with the gangue minerals dictate whether or not the ore can be processed by the cyanide heap-leach method. From a metallurgical standpoint, gold ores may be roughly classified as (1) simple oxide ores containing fine particles of native gold in a quartz or …
Chlorine, bromine, and iodine are well-known lixiviants for leaching gold, as reviewed by Tran et al. (2001). Chlorination was applied extensively in the late 19th century before the introduction of the cyanidation process. Bromine/bromide for leaching gold from ores was reported as early as 1846.

Simulations of infiltration of rock-buffered H 2 O-CO 2-As fluids into low-As pyrite (As:S = 0.01) ores reveal a continuous enrichment of As in pyrite with increasing fluid:rock ratio. The modeling suggests that upgrading of early-formed low-grade ores by multistage hydrothermal events can generate large gold deposits.
