Extraction of Tin/ Stannum-Tin- - Metalcess

Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

Extraction of Iron | Metallurgy | Blast Furnace and Reactions

Burning coke provides the majority of the heat required for this process. At such high temperatures, Coke reacts with the oxygen in the hot air to form Carbon Monoxide (CO). The CO and heat now move upwards and meet the raw material running down from the top. The temperature in the upper parts of the Blast Furnace is considerably lower than the ...

It is therefore likely that the decision will be taken to merely use the off-gases as fuel either to directly assist carbonisation or to generate power or process steam. Fortunately a decision on a refinery unlike the briquetting plant can be deferred in most cases. The refinery can be added on at a later stage if shown to be worthwhile.
