concentration is and what else is in the ore or feed. HIGH COPPER CONCENTRATION FLOWSHEETS. One group of flowsheets has evolved to handle leach liquors with very high . copper levels, often over 40 gL. In this case, the circuit designs do not rely on SX to remove all the copper in one step. The primary extraction circuit takes the

Anchor i1107984 Section 11 Time of Concentration. Time of concentration t c is the time required for an entire watershed to contribute to runoff at the point of interest for hydraulic design this time is calculated as the time for runoff to flow from the most hydraulically remote point of the drainage area to the point under investigation.

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
