The ore is broken by drilling and blasting, transported to a processing plant where it is crushed and ground and then concentrated using gravity methods. The concentrate is usually of a lower grade (about 50% tin) than placer concentrate because of the fine grain size of the cassiterite and the difficulty of removing all the associated …

Tin (Sn) content in primary tin ore ranges from 0.2 – 1.0%. The Sn particles liberated in the cassiterite mineral are above 50% so they can be processed by the physical separation method. This research aims to observe the beneficiation of cassiterite from primary tin ore (oxide and skarn samples) using gravity and magnetic separation.

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 …

Therefore, this kind of tin can't be separated and recovered only by mineral processing, and tin was remained in the magnetite concentrate. Fuming processes, such as sulfurization and chlorination roasting, are practised to separate tin from middle-grade tin-bearing materials of tin-ore tailings and tin smelting slag [8]. But the iron oxides ...

The results were compared to the results obtained by artisanal processing techniques. The proposed mechanized techniques were found to increase the efficiency of tin and tantalum recovery from 60.75% to 81.85% and from 22.9% to 48.57%, respectively, and the grades of the tin and tantalum increased to 63.75% and 35.7%, respectively.

The above cassiterite processing methods can produce tin concentrates with a tin content of 60% or higher, and a tin recovery rate of 70% or higher. Finally, the extraction of tin can be carried out according to the actual situation. The cassiterite processing is often determined by ore properties, beneficiation plants, and budget.

The tin ore has a higher density than symbiotic minerals, so the mining process of tin ore is usually gravity separation. However, tin ore is often accompanied by iron oxide minerals such as magnetite and hematite, so it is impossible to completely separate the ore only by the gravity separation method.
