Introduction. Minerals: Alluvial Gold. Capacity: 100 TPH. Feeding Size: 4mm. Process: The raw material is the alluvial gold with sticky clay, so JXSC uses Gold Trommel Scrubber to wash the gold. And the gold grader needs to reach 80% above.

Tin (Cassiterite) ore processing refers to the process of extracting tin from ore. Gravity separation, magnetic separation and flotation are mainly used to grade tin concentrate and remove other impurities. In order to achieve high efficient, low-cost beneficiation flow, JXSC will custom process and equipment according to ore characteristics.

Columbite and tantalite, either naturally occurring or synthetically produced as concentrates from tin slag, are digested with hydrofluoric acid at elevated temperatures. The accompanying elements are dissolved along with the niobium and tantalum, which form the complex heptafluorides H2NbF7 and H2TaF7.

It often uses a stage grinding process when processing nickel ore. The crushed products enter the ball mill for a stage of grinding and then enter the spiral classifier for pre-classification. If the ore particle size of nickel ore is too coarse (greater than 0.1mm) or too fine (less than 0.006mm), it is unfavorable for the subsequent flotation.
