硅酸盐氧化铜矿石的联合方法选矿如众所知,许多贫的氧化镍矿床的矿石,由于金属与围岩中的硅酸盐矿物致密结合(直到同晶形的结合)在工业上利用相当困难。原因是机械选矿法对此种矿石已无效,对于含镍不低于0.9～1％的矿石采用直接火冶法从中回收有价成分是合算的。对于有价成分含量低的矿石,在许多情况下采用粒铁法及部分水冶法处理。同样也制定
Silicate-Coated Copper Ores Process Mineralization It is well-known that the ore of many lean nickel oxide deposits is industrially utilized due to the close association of the metal with silicate minerals in the surrounding rock (up to the combination of the isomorphs) difficult. The reason is that mechanical beneficiation has been ineffective for such ores, and it is cost-effective to recover the valuable components from the direct fire-metallurgy method for ores with not less than 0.9-1% nickel. In the case of ore with low content of valuable components, the iron and iron method and the partial hydrometallurgical process are used in many cases. Also made
