随着金属铜、锌需求的增长及易选铜锌硫化矿资源的不断耗竭,细粒嵌布的该类难选矿成为重要原料.然而,由于对铜锌硫化矿大多采用优先浮选工艺,导致尾矿中金属损失普遍较大.本文针对云南某典型铜锌多金属硫化矿,采用粗磨条件下的混合浮选抛尾工艺,研究了磨矿细度、药剂种类、药剂用量等因素对抛尾过程的影响.在粗磨细度为-200目75%,乙黄药和丁黄药为组合捕收剂时,浮选抛尾量为原矿量的60%,尾矿含Cu 0.058%、Pb 0.027%、Zn 0.12%,尾矿中各金属损失率分别为Cu 3.21%、Pb 5.49%、Zn 3.35%,在各有价金属以混合粗精矿形式被回收的前提下,实现了较彻底的大量抛尾.本研究的粗磨浮选提前抛尾对铜锌多金属硫化矿资源的经济开发利用具有重要借鉴意义.
隨著金屬銅、鋅需求的增長及易選銅鋅硫化礦資源的不斷耗竭,細粒嵌佈的該類難選礦成為重要原料.然而,由于對銅鋅硫化礦大多採用優先浮選工藝,導緻尾礦中金屬損失普遍較大.本文針對雲南某典型銅鋅多金屬硫化礦,採用粗磨條件下的混閤浮選拋尾工藝,研究瞭磨礦細度、藥劑種類、藥劑用量等因素對拋尾過程的影響.在粗磨細度為-200目75%,乙黃藥和丁黃藥為組閤捕收劑時,浮選拋尾量為原礦量的60%,尾礦含Cu 0.058%、Pb 0.027%、Zn 0.12%,尾礦中各金屬損失率分彆為Cu 3.21%、Pb 5.49%、Zn 3.35%,在各有價金屬以混閤粗精礦形式被迴收的前提下,實現瞭較徹底的大量拋尾.本研究的粗磨浮選提前拋尾對銅鋅多金屬硫化礦資源的經濟開髮利用具有重要藉鑒意義.

With the continuous depletion of easy-treatment copper-zinc sulfide ore and the increasing demand for copper and zinc metal,the fine disseminated and refractory complex copper-zinc sulfide ore has become an important source for the production of concentrate. However,the utilization of preferential flotation process leads to larger loss of metal in the tailings. In this paper,an innovative bulk flotation of discarding tailings after coarse grinding is carried out for this typical sulfide ore in Yunnan province,and the influencing factors are studied, such as grinding fineness,collector types and dosage. Under the suitable conditions of rough grind of 75%-74μm,ethyl xanthate and bytyl xanthate as mixed collector,the experiments results show that the yield of discar-ding tailing is 60%,and the tailing contains about 0.058%Cu,0.027%Pb,0.12%Zn,and the loss ratio of Cu is 3.2 1%,Pb 5.49%,Zn 3.35%. The majority of valuable minerals are recovered as mixed rough concentrate.This study provides certain research foundation and it is of far reaching importance for economic exploration of copper-zinc polymetallic sulfide ore.
