泡沫泵月分级溢流经过一粗三精三扫的浮选流程后
作者: 更新日期:2021-11-24 09:23 浏览次数:
分级溢流经过一粗三精三扫的浮选流程后,取得精矿,尾矿经过自流管到砂泵池后保送到尾矿库。选矿药剂主要有石灰、水玻璃、黄药、黑药、Z-200等。
    由于入选的原矿的物品种较多,嵌存状态较复杂,嵌布粒度较细,加上在洗矿作业中的洗矿水里还有较高品位的银矿物,因而矿厂不时地对选矿工艺停止调整,寻求合适矿山的选矿药剂,进步回收率。表4.6为近年来凤凰山银矿选矿的各项指标。
61青城子含银铅锌矿的矿石特性和浮选工艺流程是什么?
 
青城子铅锌矿为铅锌硫多金属含银硫化矿。选矿厂消费范围为2000t/d。原矿含银45~55g/t。
(1) 矿石性质泡沫泵
    属中温热液充填交代矿床。金属矿物主要有方铅矿、闪锌矿、黄铁矿,另含少量黄铜矿及银矿物。脉石矿物以方解石、白云石、石英为主。铅、锌、硫金属矿物之间关系亲密,常呈粒状汇合体呈现,大局部为中粗粒结晶,组成较致密,与脉石矿物关系不甚亲密。银主要以包裹银为主,与方铅矿严密共生,散布在方铅矿中的银占74.2%,在闪锌矿中银占4.91%,黄铁矿中含银18. 47%。呈中细粒不平均嵌布,以细粒嵌布为主。

    一段闭路磨矿,细度为一0.074mm占50%,硫化物混合浮选


After the graded overflow passes through the flotation process of one coarse, three fine and three sweeping, the concentrate is obtained, and the tailings are transported to the sand pump pond through the gravity pipe and then transported to the tailings pond. Beneficiation reagents mainly include lime, sodium silicate, xanthate, black medicine, Z-200, etc.
Because there are many kinds of raw ore selected, the embedded state is complex, the embedded particle size is fine, and there are high-grade silver minerals in the ore washing water in the ore washing operation, the mine constantly adjusts the beneficiation process to seek beneficiation agents suitable for the mine and improve the recovery rate. Table 4.6 shows various indexes of beneficiation of Fenghuangshan silver mine in recent years.
What are the ore characteristics and flotation process flow of Qingchengzi silver bearing lead zinc mine?
Qingchengzi lead zinc mine is a lead zinc sulfur polymetallic silver bearing sulfide mine. The production capacity of the concentrator is 2000t / d. The raw ore contains 45 ~ 55g / T silver.
(1) foam pump for ore properties
It is a mesothermal hydrothermal filling metasomatic deposit. Metal minerals mainly include galena, sphalerite and pyrite, and a small amount of chalcopyrite and silver minerals. Gangue minerals are mainly calcite, dolomite and quartz. Lead, zinc and sulfur metal minerals are closely related and often appear as granular aggregates. Most of them are medium and coarse-grained crystals with dense composition and are not closely related to gangue minerals. Silver is mainly wrapped silver, which is closely associated with galena. Silver distributed in galena accounts for 74.2%, silver in sphalerite accounts for 4.91%, and silver in pyrite accounts for 18.47%. Medium and fine particles are unevenly embedded, mainly fine particles.
