某硫化-氧化复合型铜钴矿石工艺矿物学研究

摘要/Abstract

摘要： 采用国际先进的MLA矿物自动定量分析技术，结合传统的工艺矿物学研究方法，查明某硫化-氧化复合型铜钴矿石的物质组成和主要含铜、钴矿物的赋存特性，并对矿物进行磁性分析，为该矿石的选矿工艺研究提供指导。结果表明：①该矿石矿物组成较复杂，铜矿物以硅孔雀石为主，其次是黄铜矿、辉铜矿、孔雀石，还有少量至微量的假孔雀石、赤铜矿、斑铜矿、水胆矾等，含钴矿物则主要为铜钴硬锰矿；②各矿物共生关系复杂，互相浸染交代现象普遍，导致金云母、叶腊石、绿泥石、高岭石等多种脉石矿物中也含较多的铜和少量的钴；③主要铜、钴矿物嵌布粒度各异，黄铜矿/辉铜矿和铜钴硬锰矿属细—微细粒均匀嵌布；硅孔雀石/孔雀石属粗—细粒不均匀嵌布，假孔雀石属粗脉状嵌布；④钴硬锰矿、孔雀石、假孔雀石、褐铁矿、大部分硅孔雀石及一些脉石矿物具有程度不等的弱磁性。根据以上研究结果，建议选矿工艺研究采用先通过强磁选预富集铜钴硬锰矿、孔雀石、假孔雀石、硅孔雀石、褐铁矿和磁性脉石等，然后通过水冶从强磁选精矿中提取铜、钴，通过浮选从强磁选尾矿中回收黄铜矿、辉铜矿、赤铜矿等易浮铜矿物的技术路线，并实行阶段磨矿、阶段选别。

Abstract: The mineral composition of composite sulfide-oxide copper-cobalt ore and the occurrence state of copper and cobalt elements were investigated by the international advanced automatic quantitative mineral technology MLA combining with the traditional processing mineralogy.The magnetic analysis on the minerals is made，which provides the guide for the mineral processing.The research results indicated that ① The ore has a complex mineral composition，copper minerals are mainly chrysocolla，followed by chalcopyrite，chalcocite，malachite，as well as small amount or trace of tagilite，cuprite，bornite，brochantite，etc.，cobalt minerals are mainly copper and cobalt psilomelane；② Each mineral has complex symbiotic relationship with each other，and is widespread disseminated，which leads to lots of copper and small amounts of cobalt existing in gangue minerals of gold mica，pyrophyllite，chlorite，kaolinite and others；③ Major copper and cobalt minerals varies in size dissemination，chalcopyrite/chalcocite and copper cobalt psilomelane belong to the fine，micro-fine disseminated type;Chrysocolla/malachite belong to the crude-fine uneven disseminated type，and the tagilite belong to the coarse veins disseminated type；④ cobalt psilomelane，malachite，tagilite，limonite，most of chrysocolla and some gangue minerals own weak magnetic properties in different degree.Based on the findings above，it is recommended that the beneficiation adopts the following technical route with stage grinding and stage concentration: the copper-cobalt psilomelane，malachite，tagilite，chrysocolla，limonite and magnetic gangues are pre-enriched by high intensity magnetic separation.Then，copper and cobalt are extracted from high intensity magnetic concentrate by the hydrometallurgical mill，and some easy-floating minerals such as chalcopyrite，chalcocite，cuprite are concentrated from the high intensity magnetic tailings.
