福建行洛坑钨矿属花岗岩细脉型含钼黑、白钨矿床。原矿品位低、矿物组成复杂、嵌布粒度细。但矿床储量大,开采条件好(可露天开采),有工业价值。为了开发利用该矿区钨矿资源,我们进行了选矿流程试验,对重选—磁选—浮选等三种流程进行了系统的研究,确定重选—磁选—浮选流程为最优流程。其指标较高,成本较低。现叙述矿石性质,试验流程的确定及基础试验,三种试验流程及其指标,试验流程的评价等几个问题。一、矿石性质原矿含WO_30.238%,Mo0.0125%,Cu0.0115%,Bi0.008%,SiO_272.93%,Zn0.014%,As0.013%,Al_2O_310.58%,CaO Fujian Hangluo tungsten ore is a granite vein type containing molybdenum black and scheelite deposits. Low ore grade, complex mineral composition, embedded fine grain size. However, large deposits, good mining conditions (open pit mining), with industrial value. In order to develop and utilize the ore resources of the mine, we carried out the beneficiation process experiment and systematically studied the three processes of re-selection, magnetic separation and flotation to confirm that the re-selection-magnetic separation-flotation process is the optimal process. Its indicator is higher, the cost is lower. Are described the nature of the ore, the determination of the test process and the basic test, the three test processes and indicators, test process evaluation and several other issues. First, the nature of ore Ore containing WO_30.238%, Mo0.0125%, Cu0.0115%, Bi0.008%, SiO2_272.93%, Zn0.014%, As0.013%, Al2O_310.58%, CaO
