在连续性的选矿生产过程中,操作、设备事故及停电等都会造成金属流失,为了解决这个问题,水口山矿务局铅锌矿选厂建造了回收池,利用真空吸砂的方法将流失砂返回,收到较好的效果。从1973年10月该措施投产以来,到去年九月为止,共回收流失砂594吨,折合铅金属76吨,锌金属75吨,价值人民币18万元。真空吸砂返回过程,是利用真空将回收池的流失砂吸入分离桶,当吸至一定量后,关闭真空阀,打开进气孔,矿浆在重力作用下冲开分离桶放浆孔的胶
In the continuous beneficiation production process, operation, equipment accidents and power outages will cause metal loss. In order to solve this problem, the lead-zinc mine processing plant of Shuikoushan Mining Bureau has built a recovery pond, which uses the vacuum sand-suction method to drain the sand Return, receive better results. Since the measure was put into operation in October 1973, up to September last year, a total of 594 tons of lost sand were recovered, equivalent to 76 tons of lead metal and 75 tons of zinc metal, valued at 180,000 yuan. Vacuum suction sand return process, is the use of vacuum to recover the pool of lost sand into the separation barrel, when the suction to a certain amount, turn off the vacuum valve, open the intake hole, the pulp under the action of gravity to open the separation barrel put pulp hole glue
