建立一个选冶联合流程(在选矿系统选出中矿,然后用火冶法或水冶法处理中矿)是处理难选铜锌矿石的可行方法之一。中矿的质量(无论是在精矿精选时选出的中矿,或者是在选矿过程中直接得到的中矿)取决于相应的选中矿方法。许多国家的研究中心对铜、镍、锡、铅、银矿石采用联合还原离析焙烧进行了有成效的研究。根据贫硫化物料和混合含铅物料离析焙烧时的操作数据,锌可作为不希望的杂质,以硫化物状态分离除去。如果离析焙烧,接着浮选焙砂的结
The establishment of a joint process of coal dressing and smelting (the selection of medium-sized mines in the beneficiation system and the subsequent treatment of medium mines by fire-metallurgy or hydrometallurgy) is one of the possible ways of dealing with refractory copper-zinc ores. The quality of middling mines, whether they are medium mines selected during concentrate selection or medium mines directly obtained during mineral processing, depends on the selected method of beneficiation. Many national research centers have conducted effective research on the combined reduction and roasting of copper, nickel, tin, lead and silver ores. According to the operating data when the lean sulfide-based material and the mixed lead-containing material are separated and roasted, zinc can be separated and removed in the sulfide state as an undesirable impurity. If isolated roasting, followed by flotation calcine knot
