Beneficiation or extraction of alluvial tin ore is similar to that of alluvial gold ore. Gravity separation will be a great choice to get high quality tin concentrate. Screen will be used to remove most of the gravels and then jiggger will be used as rough separator while shaking table is used as fine separator to gain final tin concentrate.

The concentration of alluvial tin ore is mainly gravity separation with mainly jigger, shaking table, and spiral chute involved while sometimes centrifugal separator is involved for some fine tin ore. Here is some tin enrichment flow sheet to share with you.

The processing line for alluvial tin ore screening-jigging gravity separation-milling-shaking table sepration. Vibration screen is used to remove the big gravels over 30 mm. -6mm ores will be put into the jigger for jigging separation while 6-30 mm ores will be put into impact crushers before second jigging. The concentrate from jigger covers simple tin and tin with impurities. In this situation, milling will be needed to liberate tin from impurities. And the liberated mixture will go for shaking table for further enrichment to get final tin concentrate.
