摘要	NONFERROUS METAL SULFIDES, ANTIMONIDES AND ARSENIDES IN MINERAL CRYSTALLINE FORM, E.G. AS ORE, CONCENTRATES AND METALLURGICAL TAILINGS, BYPRODUCTS AND WASTE MATERIALS, ARE COMMINUTED, IN FOR EXAMPLE, A VIBRATING MILL BY IMPACT TECHNIQUES (VIBRATING IMPACT MILL) UNTIL THE X-RAY DIFFRACTION OR INTERFERENCE INTENSITY IS REDUCED, E.G. TO A RATIO OF COMMINUTED INTENSITY TO ORIGINAL INTENSITY OF LESS THAN 0.8. THE COMMINUTED PRODUCT IS THEN TREATED IN A SINGLE STEP WITH OXYGEN AND A LIXIVIANT FOR RECOVERY OF THE NONFERROUS METAL OR A SALT THEREOF. THE LATTER IS FOUND IN SOLUTION IN THE AQUEOUS PHASE.
