摘要：A kind of method of the present invention is for extracting metal from metalliferous material, especially waste material, pass through pyrohydrolysis, metalliferous material, these materials include that at least one or more metal includes to be selected from Zn, Cd, Pb, Hg, Cu, Sn (such as tin (0) tin (II)), As, Sb, Au, Ag and Bi, it is to look like reaction at 700-1100 °C, it is advantageously 800-900 °C, with gas componant, which includes at least the vapor of 25-45% volumes %, the carbon dioxide of 0-12% volumes %, the hydrogen chloride of 2-20% volumes %, the carbon monoxide of 0-15% volumes %, remaining is nitrogen or oxygen, the metal is the volatile metal chlorides extracted from above-mentioned group of form. More specifically, metalliferous material, using one kind comprising one or more metals comprising being selected from Fe, Cr, Mn, Ni, Mg, Ca, Al, Si, Ti, Co and Zr, last group of material is hydrolysis, at reaction conditions, make non-volatile metal oxide, or remaining, oxide form or form (2) non-volatile metal chloride, therefore the raw material of remaining belting.
