Leachox™ Refractory and Sulphide Gold Process

Refractory gold ores are generally defined as those ores that do not give economical recoveries in conventional cyanide circuits where the ore has been ground to around 53 to 75 microns. The gold is normally present in refractory gold sulphide ores containing mainly pyrite, arsenopyrite or pyrrhotite and occurs in both the chemically bonded state and as micro or nano-size grains of metallic gold.

Arseno/redox process for refractory gold ores -

1989-1-1  Arseno Processing Ltd. has been developing a nitric acid based process for treating refractory gold ores and concentrates since 1981. The technology is being marketed as the Redox Process. With the participation of Minproc Engineers, the process has been operated on a continuous pilot scale with both a low sulphide whole ore and a high sulphide arsenopyrite concentrate.

Refractory gold ore pretreatment Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of roasting.

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

economic cut-off gold grade for refractory ores is somewhat higher than non-refractory ores. The mining industry uses a “rule of thumb” of 80% gold recovery to define the transition from a refractory to a non-refractory gold ore. Ones under 80% are considered refractory. In assessing the economic benefit of the extra processing

2019-8-31  Presently, one-fourth of the world’s gold production is contributed by the refractory type of gold ores. The gradual depletion of free milling gold ores will eventually lead the future gold projects to rely more on refractory gold (Yang et al. 2013). A proper understanding of the formation of refractory Au ores and characterisation of such ores will therefore be helpful in finding new analogous deposits and
