Case Study Flowsheets Coppergold

Jan 01, 2005 The conventional treatment of coppergold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. The conventional treatment of coppergold concentrates does elicit some compelling reasons to seek an alternative hydrometallurgical process for the recovery of concentrate values.

Flowsheet Development For Gold Orebodies Sgs

The main disadvantage is that gold recovery is generally lower than that achieved by grinding to a finer size and leaching in stirred tanks. In addition, the rate of leaching is slow and recoverable gold can be held up in the heap for months, which impacts cash flow. There can also be longer term environmental

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
