Tin Extraction
However, the tin concentrate grade of 40% is required, meaning the enrichment of hundreds or thousands times. Targeting at the refractory tin ore, low grade tin concentrate is obtained and it has to be further extracted by special metallurgy process. Reduction smelting is the dominant process to extract tin metal from tin concentrate.

Understanding the Tin Mining Process: What You Need to Know
Smelting: After concentration, the tin ore undergoes smelting. This involves heating the ore in a furnace at high temperatures, often with a carbon source (such as charcoal), to reduce the tin oxide (SnO2) to pure tin metal.

The subsequent smelting process can be carried out in closed shaft furnaces under reducing conditions. If the sulphur content is completely removed by roasting, the ore can be reduced directly to metal. If the ore still contains sulphur, matte (in most cases CuFeS matte ) with different amounts of copper will be produced.

Extraction of Copper: Detailed Process
The ore is ground into a fine powder and then suspended in water. Included in this are Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids, etc.) enhance the non-wettability of the metal portion of the ore, allowing it to form froth, whereas Froth Stabilizers (cresols, aniline, etc.) maintain the froth.
