(一)概述大厂矿务局长坡矿选矿厂是处理锡石多金属硫化矿石的选矿厂。选矿厂采用重介质旋流器预选,其重产品经重选—浮选—重选、矿泥集中浮选锡石的工艺流程处理。目前产出重选锡精矿、浮选锡精矿、铅锑精矿、锌精矿、硫砷混合精矿以及重介质尾矿和总尾矿共七种产品。由于未做金属平衡工作,难以评价生产技术和管理水平的高低,生产仍然是处于盲目状态。要进
(A) Overview Dachang Mining Secretary slope mineral processing plant is dealing with cassiterite polymetallic sulfide ore dressing plant. Concentrator using heavy medium cyclone preselected heavy products by gravity election - flotation - re-election, concentrated flotation process of cassiterite process. At present, seven kinds of products are re-selected for tin concentrates, flotation tin concentrates, lead and antimony concentrates, zinc concentrates, arsenic and sulfur mixed concentrates, and heavy medium tailings and total tailings. Due to the lack of metal balance, it is hard to evaluate the level of production technology and management, and the production is still in a blind state. To enter
