How to extraction tin from tin ores
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.
