Once the oil sands is hauled out of the mine the ore is first processed in an Ore Preparation Plant OPP where clumps of oil sands are broken down and mixed with hotwarm water to produce a pumpable slurry OPP facilities have evolved considerably in recent years and provide a critical first step in the extraction of bitumen3397
Lime has an inhibitory effect on the floatation of sulphurcoppersilver ore light red silver ore and deep red silver ore However it has less influence on tellurium silver ore and argentite Cyanide and sodium sulfide have a strong inhibitory effect on many silver minerals especially natural silver4457
To extract the platinum group metals from the ore and to refine them to the very high purity required for their many applications requires a multitude of complex operations At present the final refining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals but this is inefficient as far as the4104
After ore sorting and grinding used in both types of ore the main technique used for concentration of sulfide ores is froth flotation followed by smelting and refining pyrometallurgical process while in the case of oxide ores and some low grade sulfide ores a heap leaching process is combined with solvent extraction and electrowinning SX4432
