Abstract

Non-ferrous metals e.g. Cu, Ni, Zn, Co, Sn, U and partic. Au, and Pt metals are extracted from prim. and sec. ores, concentrates, Mn-contg. ores, thermal leaching sediments, metallurgical inter and by-prods, and ind. wastes by leaching the matl in particulate form with a soln. composed of Mg chloride and/or other alkali chlorides contg. 50-350 g NaCl/l, and nitric acid of about 3-90 wt.% concn., and at a temp. 20-110 degrees C. The leaching process is carried out for a period of 30 min to 5 h, and pref. by mechanically and/or pneumatically stirring the mixt. The leaching soln. is made up by mixing the respective substances corresponding to the required concn. of H+-, Cl--, and NO3- ions, and by using dosing units and instruments for feeding the addns to the leaching unit. Pref. the soln. is made up by using waste nitriding acids, or natural salt solns., seawater or suitable industrial waste waters contg. salt. The waste leaching soln., which is regenerated, and the steam condensates are recycled.
