FIELD: metallurgy.
SUBSTANCE: invention relates to method for enrichment of slurries from nickel electrolysis and other products containing platinum metals, gold and silver as well as to method for reprocessing of products obtained by processing of sulfide copper-nickel ores. Claimed method includes slurry autoclave oxidative leaching followed by flotation. Leaching is carried out at 108-110°C and oxygen partial pressure of 0.4-1.0 MPa.
EFFECT: concentrate with low content of non-ferrous metals.
