The role of pulp chemistry in the flotation recovery of

Cobalt ore is mined from the open pit at a grade of 1.30-1.80% Cu and 0.20-0.80% Co. The copper ore is a complex mixture of sulphide and oxide minerals and processing consists of sulphide flotation followed by sulphidisation and an oxide flotation step. The work reported in this study involves that ofthe underground copper ore only.

How to Prevent Corrosion of Copper Tube in Underground or

Out-of-sight, out-of-mind. That's the phrase that comes to mind for all who have installed copper and copper alloy piping systems in buried, underground applications. An expectation well supported by the excellent corrosion resistance of copper alloys used in these applications. An expectation that may not be realized when this out-of-site, out-of-mind philosophy extends to the practices used
