High temperature pressure oxidation of a lowgrade nickel concentrate was examined to demonstrate the potential benefits and shortcomings of this approach. The high iron sulfide content ensured that acid generation was much greater than for higher grade concentrates. This results in the formation of basic iron sulfate phases and a significant amount of sulfuric acid. Kinetic sampling during ...

Jun 27, 2015· Metal value recoveries in extraction are the key issue for sustainability of metals. The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte (a Cu–Fe–S–O melt) and silicasaturated iron silicate slag were determined at 1250–1350 °C, under controlled oxygen and sulfur pressures and at fixed partial pressure of sulfur dioxide, in silica saturation for target ...

cobalt recovery from other feedstocks, particularly mattes and laterites, and for recovery of other metals, especially gold and zinc. This process will be discussed later. In the 1970s, interest grew in the zinc pressure leach process, which offers the luxury of the elimination of sulphur dioxide emissions when processing zinc sulphide ...

The OPD prevented the sulfur from wetting the mineral surfaces, allowing the catalytic effect of the silver ions to be maintained. A simple mathematical model was formulated to explain the leaching and passivation of chalcopyrite at low temperature (110°C).

For low sulphur steels used for a low pressure turbine rotor in order to improve mechanical properties, it became a problem for an onset temperature of overheating to shift low temperature with ...

ABSTRACT SAIMM HMC 2009 Conventional analytical laboratories by their very nature are very manual. Sample preparation is slow and laborious, samples are moved from stage to stage manually and, typically, all samples are processed in batches so a sample which is the first to be milled has to wait for the completion of the batch before it advances to the next stage.
