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.Web

Extraction of tin from its ore generally adopts a gravity separation method, which is determined by the density of tin ore than the characteristics of paragenetic minerals. However, iron oxides such as magnetite and hematite are often associated with tin ores, so for those types of tin ores, the gravity separation is not possible.Web
