Copper–gold ore processing with ion exchange and SART ...

2014-10-1  Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more of copper. The PLS is treated by column ion exchange, using Dow’s gold-selective MINIX resin. Loaded resin is stripped with an acidic thiourea solution, from which gold and silver ...

2016-1-1  As expected, the copper in the circuit reduced to a low level, but when sulfide copper–gold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined. The copper recovery plant was operated intermittently for a few months and was eventually shut down.

Fatigue has a significant impact on the economy of a region. This is because it leads to absenteeism, decreased productivity, health costs, and accidents. It is something complex primarily caused by 2 factors, including work and non-work fatigue. The purpose of this study therefore is to determine the factors associated with the fatigue level in copper and gold ore processing workers.
