FIELD: metallurgy.
SUBSTANCE: method includes ore reduction, batching of crushed ore with sulfur and sodium chloride, charge burning at presence of water vapor and following leaching by solution, containing sulfuric acid. Before burning it is implemented batch pelletising. Leaching burnt granules is implemented by solution, consisting about 5 g/l sulfuric acid and 50 g/l ammonium sulfate.
EFFECT: sulfuric acid reduction of consumption while leaching.
