Cassiterite Tin Ore Extracting Plant & Process

Gongyi Forui Machinery Factory is a professional mineral processing machine manufacturer in Gongyi, China. Our products include jig separator, magnetic separator, flotation machine, gold separator, grinding machine, classifier equipment, etc.
 
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.

Firstly, the raw alluvial tin ore shall be screened into two size ranges and the specific size will depend on the ore itself. Here taking 2mm for example, the +2mm ore goes for rod mill to liberate the tin granules from impurities. -2mm ores will go for jigger for jigging separation. The first phase jigging is to get the tin to the largest extent while the second jigging separation is to upgrade tin as fine selection by removing the intergrowth of impurities. Concentrate from the second jigging can be final conconcentrate. Tailings from first jigging and +2mm tin ore goes for ball mill for further milling and the fine tin granules can be liberated, and the output from the rod mill will go for tin jig separation machine for further jigging. The tin concentrate from the final jigging can be final concentrate while the tailings can go for shaking table for separation to recover the fine tin.

With years' efforts, Forui have gained appreciation & praises from customers all over the world. Our products have been successfully exported to many countries and regions, like Thailand, Laos, Myanmar, the Philippines, Indonesia, Nigeria, Namibia, South Africa, Russia and the United States, etc. Welcome to visit our factory!
