INTERACTION OF METALS AND THEIR OXIDE COMPOUNDS WITH AMMONIUM CHLORIDE

In this research work the conduct of some metals and, mainly, their oxide compounds in ammonium chloride solutions that are formed at the enterprises, which engaged in an affinage of metals of platinum group as middlings productions, is investigated in a series of search experiments. The use of these solutions can raise the enrichment level on the PGMs of hydroxide sediments of affinaging production and lower the costs of the used reagents.
