Tin Extraction

However, the tin concentrate grade of 40% is required, meaning the enrichment of hundreds or thousands times. Targeting at the refractory tin ore, low grade tin concentrate is obtained and it has to be further extracted by special metallurgy process. Reduction smelting is the dominant process to extract tin metal from tin concentrate.

How to Extract Tin from Tin Oxide Ore?

Jun 23, 2020  3. Related tin extraction equipments. Tin exists almost in the form of cassiterite (tin oxide) in the earth's crust. Its density is relatively large, so gravity separation is most used for tin extraction. In the pre-dressing stage of tin oxide ore, the common equipments are trammel screen, cyclones, rod mills and other equipment.
