Testing Refractory Gold Ore
Refractory Ore Pretreatment Processes. A "fine" grind in a gold production plant might produce a particle size distribution in which 80% of the ore is finer than 44 µm. Ultra-fine grinding can be defined as a process that produces an 80% passing size of 20 µm or less. Depending on the size distribution of gold particles, ultra-fine ...

Three check-assays gave an average of 0.083 oz. of gold per ton (or $1.74), which shows an extraction of 93.46 per cent. During the leaching, 50 gal. of wash-water was used, which is equivalent to 1,338 gal. per ton of ore. This large excess was due to the care taken to remove the last traces of gold chloride from the ore.
