A Review on Reagents and Processes of Fine-Grained ...

Tin resources are abundant and complicated in China. Most of tin resources come from cassiterite. Normally the main beneficiation method of coarse cassiterite ore is gravity separation. However, as for the fine-grained cassiterite, flotation and joint processing techniques are generally selected to improve the low recovery from gravity separation.

How to Extract Tin from Tin Oxide Ore?

Due to the high density of cassiterite (6.4~7.1g/cm3), gravity separation is often used to process cassiterite. However, cassiterite is easily sludged in the nature and in the process of ore sorting. Therefore, flotation is also used to recover fine-grained cassiterite from the fine mud and tailings. 1. Why is tin oxide ore extraction so ...

Cassiterite is present in a variety of vein and greisen structures. In the hornfels, coarse-grained quartz and quartz- topaz veins cross-cut sedimentary layers and fill partings along bedding in the meta-sedimentary rocks. These veins contain up to several percent fine-to coarse-grained black cassiterite and minor amounts of wolframite.
