采用浮选和团聚法回收复合矿石中的金属[《欧洲专利局专利533224-A2》报道]从含有k种金属的复合矿中回收金属,尤其是回收其中i种金属(i为1～k,i、k=1、2、3…)的方法包括:(a)将矿石细磨,使i种金属矿物中至少有一种金属矿物与脉石矿物解离而形成细磨矿浆;(b)浮选调浆;(c)至少用一段浮选作业选别细磨的矿石,得到浮选精矿与浮选尾矿,浮选精矿含有富集到能有效回收的主种矿物;(d)将浮选精矿再磨,以使得到的矿物中至少有一种、至多有i种金属矿物与脉石矿物解离;(e)团聚的调浆作业;(f)至少采用一段团聚作业,以获得一种团聚体,该团聚体中含有较高品位的矿物;(g)对团聚物进行分离,以得到团聚精矿和含脉石矿物的尾矿。
Recovery of metals in composite ores using flotation and agglomeration methods [“EP Patent 533224-A2”] Recovery of metals from composite mines containing k metals, in particular for the recovery of metals from among them (i is from 1 to k, i, k = 1, 2, 3, ...) comprises: (a) finely grinding the ore to dissociate at least one metallic mineral of the i metallic minerals from gangue minerals to form finely ground slurries; (b) (C) selecting finely ground ores for at least one flotation operation to obtain flotation concentrates and flotation tailings, the flotation concentrates containing principal minerals enriched for effective recovery; (d) Resurfacing the flotation concentrate so that at least one of the minerals present is dissociated by at most i metal mineral from the gangue mineral; (e) a sizing operation for agglomeration; (f) at least one reunion operation Obtaining an agglomerate containing higher grade minerals; (g) separating the agglomerates to obtain agglomerated concentrates and tailings containing gangue minerals.
