PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

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.
