Self-assembling of nanodispersed forms of platinoids as a method of their extraction on the example of gold-silver ores of the milogradovsky mining (Primorsky region)

Abstract

The paper contains the results of platinum self-assembling from nanodispersed platinoids into gravity-extraction metallic ones. It is shown that nanosized forms of noble metals, platinum in particular, are often beyond the capabilities of modern technology methods of noble metals extraction. Self-assembling is innovative way of extraction which is the way of the future. This technology based on so-called Matvienko-Kalashnikov effect, which appearing in the overbalance contents of noble metals that appear in the course of super-fine grinding of ore, containing so-called cluster forms. The actual data on the distribution of platinum in the original ore are given, the forms of the “assembled” aggregates and the results of their microprobe study are shown.
