The flow sheet of alluvial tin ore is usually very easy with simple screening and gravity separation involved to get high grade tin concentrate. For alluvial tin of low single separation degree, ore milling and further gravity separation will be needed after screening and gravity separation to guarantee the concentrate grade and recovery of the whole tin beneficiation processing line.

The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.
