HYDROCARBONYLATION PROCESSES OF COPPER RECOVERY FROM TECHNOGENIC RAW MATERIALS

The main goal of the study performed in this paper is the improvement of disposal and processing of technogenic wastes with high nonferrous metals content. In particular, the peculiarities of the copper recovery process from technogenic raw materials by using a hydrocarbonylation method are considered. A substantiation of the real possibility of selective copper recovery from polycomponent solutions, formed as a result of technogenic raw materials repulping or leaching, is adduced. At that, the primary reagent is carbon monoxide and the duration of the process cycle is not to exceed 10 hours at low specific power consumption and the high purity of product copper
