Bulk minerals recovery, for example tin, tantalite and chrome, differs from precious metal recovery, such as gold and platinum, in that there is more of the concentrate to catch.
In most cases bulk minerals are heavier than the carrier rock, so it is possible to use simple gravity methods. The concentrating equipment you use needs to be able to take a bigger amount of concentrate, for example spirals or a shaking table.
This sort of plant is standardly more expensive, however an affordable, entry-level option to bulk mineral recovery is to use two of APT's GoldKacha concentrators side by side. Two concentrators fill up with the heavy mineral quicker, so while you are emptying the one the other one keeps on catching. The GoldKacha is in fact called the 'TinKacha' by some of our clients who have used it successfully for tin recovery.
