the reduction of copper in mill feed generally increases gold recovery and decreases processing costs. Where the copper and gold is to be recovered by flotation the overall recovery of coarse and free gold is increased and the treatment charges and payment terms are improved by …
used for the operation, and the hole was machined from both ends. The process can also be used effectively for trepanning molybde-num; for example, the axial hole in an experimental, molybdenum alloy, tube extrusion blank was machined by EDM, using a hollow carbon electrode.
Reagent optimization is an important consideration for large PGMs processing operations because the correct improvement opportunities to flotation recovery and grade [5,6]. Also, the cost of reagents typically runs into tens of millions of dollars per annum for a large PGMs operation,
Copper and gold concentrate grade vs. ΔEh curves behaved in a similar manner, displaying a maximum at around 0.1 V. Silver behaved similar to copper up to ΔEh 0.1 V and similar to lead thereafter. Interestingly, iron concentrate grade showed a maximum at the ΔEh of the minimum grade of copper and silver (i.e., at 0.05 V).
