FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy of non-ferrous metals and can be used in processing concentrates, industrial products and solid wastes containing metals. Metal ions are extracted from cake obtained after sintering and leaching of tungsten concentrate by sulphatising calcination, which is carried out by oleum at L:S = 1:1, temperature = 250–300 °C and time 4 hours followed by hydrochlorination of sulphate sintered mass 2 n HCl solution, 240 g/l NaCl.
EFFECT: method allows intensifying the leaching process with more complete extraction of metals into the solution.
