How to Extract Tin from Tin Oxide Ore?
2.2 Separation of vein tin ore. Vein tin ore varies from alluvia tin, it exists in the rock and forms a deposit or ore bed with associated metal or non-metallic minerals. The ore dressing process of vein tin ore is more complicated than that of alluvia tin, but it still uses gravity separation to treats the vein tin ore in actual production.

A process for the direct recovery of tin values, as organo hydrocarbyl tin compounds, from reduced but unrefined tin ores and ore slags is described, wherein the ore or slag is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be separated from the tin-depleted ore or slag residue.
Simulation to Recover Niobium and Tantalum from the Tin Slags …
Table 2 shows how much metal is recovered with a feed of 1 t/h of ore. The main difference between these metals is that tin is recovered after two metallurgy processes using a very small number of reagents. A total of 0.50 tons of tin are recovered per hour and considerably lower amounts of Nb and Ta.
