Tin Ore Beneficiation Methods And Some Practice
The gravity separation method is generally used for sand tin ore. The process of gravity separation of tin sand ore usually adopts multi-stage grinding and multi-stage separation process. Those processing can make tin ores dissociation and get recovered in the early stage processing and also remove some tailing to avoid uneven embedding.
