Read More >Experiments conducted on the extractions of gold using alkyl sulphides have shown that not only can gold be separated from the platinum group metals other than palladium but a kinetic separation of gold from palladium may well be possible.This is due to the fact that palladium.
Read More >A method of performing an aqua regia leach on a mixture of pgms and gold wherein prior to the leach step the pgms and gold are alloyed with lead by fusing a lead compound, a flux and a reductant for the lead compound if necessary, allowing the melt to solidify, removing the slag formed and dissolving the lead in nitric acid, the alloying procedure tending to render ruthenium and iridium less.
Read More >A method of separating palladium from a mixture of pgms which contains palladium and at least one other pgm, the method comprising the formation in solution of the amine complexes of the metals present with the metals being in a reduced state and precipitating out the palladium by means of dimethylglyoxime provided that where platinum is present the precipitation is effected at a ph of about.
