广东砂锡矿的开采,自从广东-1型跳汰机试验成功和在生产中应用后,改变了过去生产落后、回收率不高的局面。但是细粒锡石的回收尚未达到最大的限度,其主要原因是采场来矿浓度过低,含泥量多;矿浆通过跳汰机时,流速快且矿浆比重增加,因此严重影响锡石回收,特别是细粒锡石的回收。为了强化选矿过程,进一步提高选矿回收率,解决跳汰前原矿的脱泥浓缩问题,是重要措施之一。
Since the successful test of Guangdong-1 jig and its application in production, the production of sand and tin mine in Guangdong has changed the past situation of backward production and low recovery rate. However, the recovery of fine-grained cassiterite has not yet reached the maximum limit, the main reason is that ore-bearing concentration in the stope is too low and mud content is too high. When the slurry passes through the jig, the flow rate is fast and the proportion of the slurry increases, which seriously affects the recovery of cassiterite , Especially the recovery of fine-grained cassiterite. In order to strengthen the beneficiation process, to further improve the recovery rate of mineral processing, to solve the problem of mud de-mud concentration before the jig is one of the important measures.
