云锡砂锡氧化矿的组分复杂,锡、铁致密共生,锡石嵌布粒度细,属难选矿石。随着原矿性质的变化,锡品位逐年下降,矿石日趋难选。单一重选流程已不能满足生产需要,应用各种工艺组成的联合流程选别云锡砂锡矿势在必行。 1973年以来,磁-重联合流程的研究取得了较大进展。在探索性试验的基础上,用工业型的磁选机,半工业型的摇床、水力分级机和磨矿机等设备进行磁-重和重-磁-重两种联合流程与重选流程的对比试验。
Tin oxide tin oxide tin oxide complex composition, tin, iron dense symbiosis, cassiterite fine cloth, is refractory ore. With the changes in the nature of the ore, tin grade declines year by year, the ore is increasingly difficult to pick. A single re-election process can no longer meet the production needs, the application of a combination of processes composed of a combination of tin-tin sand tin is imperative. Since 1973, great progress has been made in the research of the magnetic-heavy combined process. On the basis of exploratory tests, magnetic-heavy and heavy-magneto-heavy two joint processes and reselection processes are carried out with industrial magnetic separator, semi-industrial shaker, hydraulic classifier and grinding machine and other equipment Comparison test.
