TREATING GOLD ORES AZ

MILLING OF GOLD ORES The milling of gold ores is usually preferable to shipment to custom smelters providing the ore responds to milling treatment at a reasonable cost and also providing the ore body is of sufficient size to justify the expenditure necessary for constructing and equipping the milling plant.

Bodie History: Milling Ore from Bodie Mines

Ores, such as Bodies, that responded to treatment without roasting were considered freemilling. Other districts were less fortunate. The complexity of their ores required more expensive milling methods, and the mines had to deliver ore high enough in grade to cover the added cost.

Refractory Gold Mining SGS

In assessing the economic benefit of the extra processing that needs to be done to improve recovery from refractory or partially refractory ores, it is always important to consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.

Copper Mining and Processing: Processing of Copper Ores

Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are higher, ultimately more copper can be extracted.
