Ultra fine milling for the recovery of refractory gold ...

Submicroscopic gold is liberated by destruction of the sulphide with processes based on the use of thermal, chemical or biological oxidation. If the encapsulated gold is coarser in size, ranging say, from 1 or 2 microns to approximately 20 microns, then liberation can also be achieved by ultra fine milling

Ultrafine Grinding Turbomilling Process

Table 3 shows the size analysis of the coal after milling with Ottawa sand in water, and table 4 shows the size after milling in diesel fuel. After milling in water for 15 min, 45 to 74 pct of the plant-grind coal was finer than 2 µm. The production rate of the minus 2-µm coal, as shown in figure 3, decreased as the milling time increased.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m
