OPTIMIZING HYDRAULIC TRANSPORT PARAMETERS OF LEACHING ORES NONFERROUS METALS WASTES

Data on trends in the world economy in connection with the consumption of non-ferrous metals are given. Details of the chemical effects on the environment of toxic components of mining and processing wastes of non-ferrous metals are detailed. The environmental nature of technologies with leaching of metals and the relevance of this direction in the extraction of non-ferrous and rare-earth metals are shown. The dependences of the magnitude of the hydraulic resistances on the velocity of the hydraulic mixture and its density have been experimentally established and the adequacy of these dependences is checked by comparing the experimental data with the calculated values. It is shown that optimization of transportation parameters of tailings of enrichment allows to reduce the volume of release of chemically dangerous products of leaching into the environment.
