1. Tin ore beneficiation methods
Tin ore beneficiation methods are determined by tin ore characteristics. Cassiterite density is higher than its coexisting minerals, so traditional tin ore beneficiation method is gravity separation. In recent years, as cassiterite particle size becomes fine and fine, cassiterite flotation appears. In addition, because the tin minerals often contain a variety of iron oxide minerals, such as magnetite, hematite and limonite, which cannot be well separated by flotation and gravity separation. So, magnetic separation is put into use in the tin ore beneficiation process.

2. Tin ore grade
Tin ore grade sands for tin content more or less. High-grade ore will get more concentrates than low-grade ore under the same conditions. At the same time can reduce the cost of grinding and ball consumption. Therefore, ore grade is one of the factors affecting the production of concentrates. Some of the concentrators began to take some measures to improve ore grade and concentrates grade, as well as reducing tailings grade & metal loss. Grinding cost takes the higher part of concentrator costs. Effective and reasonable control of the grinding fineness can directly reduce mineral processing costs, and improve economic benefits of tin ore processing plant.

3. Tin ore grinding fineness
Grinding fineness is one of many factors affecting the beneficiation index. Grinding fineness directly affects concentrates grade and recovery. In production, under the premise of beneficiation technology requirements, should feed ore reasonably, to make sure as much as possible that ore size is uniform, lump& powder ore ratio is reasonable.
