Acid pressure oxidation is a promising process for these materials and silver recovery will play a major role in the economy of the process. However, in acid pressure oxidation processing, silver is incorporated into

The mixed sulphide­oxide ores contain per cent Cu and per cent Co. These ores are also concentrated by flotation with an alkaline sulphydrate. In this case, a sulphide concentrate with 46 per cent Cu and per cent Co and an oxide concentrate with Effective bromine water leachate solutions for recovery of noble metals can be prepared by diluting the concentrate corresponding to the present invention. Before or after dilution it is possible to adjust the pH by adding either a mineral acid or of its source, for example, HBr, HCl or Cl 2

PTC-1a is intended as a replacement for PTC-1, the stock of which is exhausted. It is a noble metals-bearing sulphide flotation concentrate of Sudbury ore. PTC-1a is composed of chalcopyrite, pentlandite, and pyrrhotite, with small amounts of quartz, feldspar, pyroxene, epidote, mica, pyrite and bravoite.
