ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques because of the large difference in specific gravity between gold SG 19.3 and most gangue minerals SG 2 to 3. For gold ores that are amenable to gravity separation recovery of the coarse

Processing Refractory Gold Hydrometallurgy Leaching In

There are a number of factors that cause refractory behaviour in gold ores. Typically when we start investigating these ores the first step would be to undertake a mineralogical analysis that will tell you if your ore is sulphide refractory and the grain size you are needing to target for liberation if you have pregnant solution robbers or if you have a more complex telluride or double .
