    • The present invention relates to improved process for beneficiating an ore-containing sulfide material. In particular, the process is useful for beneficiating ores and recovering metals such as gold, copper, lead, molybedenum, zinc, etc., from the ores. In one embodiment, the process comprises the steps of:(1) forming a slurry comprising at least one crushed mineral-containing ore, water and a collector which is at least one metal salt of a phosphorus acid represented by the Formula: ##STR1## wherein each R.sub.1 is independently a hydrocarbyl, hydrocarbyloxy or hydrocarbylthio group having from 1 to about 18 carbon atoms, each X is independently oxygen or sulfur, and wherein the metal is i) at least one single metal having a lowest oxidation state of plus two or ii) at least one mixture of metals wherein at least one of the metals has a lowest oxidation state of plus two, provided that when the primary mineral is copper, zinc or silver, the metal (i) is other than zinc.(2) subjecting the slurry from step (1) to froth flotation to produce a froth; and(3) recovering a mineral from the froth.
    • 本发明涉及用于选矿含硫硫化物材料的改进方法。 特别地,该方法可用于从矿石中选矿和回收金属如金,铜,铅,钼,锌等。 在一个实施方案中,该方法包括以下步骤:(1)形成包含至少一种破碎的含矿物矿石,水和收集器的浆料,该矿物质是至少一种由下式表示的磷酸的金属盐: (I)其中每个R 1独立地为具有1至约18个碳原子的烃基,烃氧基或烃硫基,每个X独立地为氧或硫,并且其中金属为i)至少一种具有最低氧化态的单一金属 加上两个或ii)金属的至少一种混合物,其中至少一种金属具有最低的氧化态加二,只要当初级矿物是铜,锌或银时,金属(i)不是锌。 (2)对来自步骤(1)的浆料进行泡沫浮选以产生泡沫; 和(3)从泡沫中回收矿物质。
