某金矿全泥氰化锌粉置换厂工艺流程技术改造实践
摘要:该矿石属少硫化矿物石英脉含金矿石,金属矿物主要为黄铁矿;脉石矿物主要为石英,其次为长石、方解石、云母等。矿石中的金元素以自然金的形式产出,并且以裂隙金为主,属于易氰化浸出矿石。经过现场工业生产调试结果证明,采用全泥氰化—锌粉置换工艺流程代替浮选处理该矿石是正确的,尾矿品位由0.57g/t降到0.20g/t,金的回收率由82.87%提高到92.16%,提高了企业的经济效益。

Abstract: The ore is a sulfide mineral quartz vein ore less, metal minerals is mainly pyrite; major gangue mineral is quartz, feldspar, calcite, followed by mica. Of gold in Ores by natural gold in the form of output elements, and fissure gold, is easy to cyanide leaching of ores. After the industrial production debugging results show that, using the all sliming cyanidation - zinc powder replacement process for flotation treatment of the ore is correct, tailing grade from 0.57g/t to 0.20g/t, the gold recovery rate from 82.87% to92.16%, increasing economic benefits of enterprises.
Key words: all slime cyanidation - zinc powder replacement; flotation; replace; recovery rate; economic benefit
该金矿自1998年建成投产以来,选矿技术人员围绕着如何提高选矿技术指标和经济效益,对选矿工艺流程进行了多次的变更和革新。对工艺技术参数不断进行修正,使之趋于合理。

1.1矿物组成及嵌布特征
该矿石的矿物组成比较简单,金属矿物主要为黄铁矿,偶见有方铅矿、黄铜矿、闪锌矿、白铁矿、毒砂。脉石矿物主要是石英,其次为长石,方解石、云母等。
