Abstract

The test data obtained at the automated test facility designed to study kinetic parameters of copper ion precipitation by sulfhydryl collectors are discussed. The row of copper ion bonding by diethyldithioccarbamate, butyl xanthate and isobutyl dithiophosphate was established experimentally by the jumps in potentials for a copper electrode, the compliance with the published data on the product of solubility of copper compounds with dithiocarbamates, xanthates, dithiophosphates is obvious. The aggregate structure is characteristic of precipitates produced by depositing copper cations by a collector with less number of hydrocarbon radical in each test group of sulfhydryl collectors. The most finely dispersed precipitates are formed using isobutyl dithiophosphate and butyl xanthate.
