FIELD: chloride methods of metal recovery from ores; may be used in nonferrous metallurgy in processing of difficult-to-work ores of noble metals. SUBSTANCE: method includes heat treatment of ore and/or its concentrate in the presence of reagent - aqueous magnesium chlorides, mainly, in composition of natural minerals and technical salts: bischofite and/or carnallite and/or tachhydrite. Burdening of ground ore and/or its concentrate with reagent is carried out in ratio of 1 wt.p. of ore for 0.05-3 wt.p. of reagent, and heat treatment is conducted at temperature of 400-600 C for 20-40 min. Conditions of heat treatment of ores with different content of sulfides and conditions of their leaching are offered. EFFECT: reduced number of used reagents, temperature and power consumption in the process with higher degree of recovery of metal; improved ecological conditions. 6 cl, 2 tbl
