In tin mining in Plateau, the open cast mining method was used because the plains of Plateau were flat and tin was concentrated in old stream beds and was washed down from the younger granite outcropping units (Gyang & Ashano, 2010). Tin was mined from the Jos Plateau, with the cassiterite mineral coming from the plateau highlands.
A major and primary Lead mineral is galena (PbS) which comprises of 86.6% of lead. In order to smelt this mineral, a blast furnace is needed to be used.

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …
Tin Mining begin with Removal of Overburden. In the geological notes earlier in the paper it was stated that volcanic disturbances had taken place since the laying down of the drifts, and that these deposits had been completely buried by the lava or basalt. It is obvious, therefore, that this basalt must be removed before the underlying alluvia ...

When looking at mining stocks, it's easy to only focus on the finished product that you are investing your money in. Whether that's uranium, gold, silver, palladium or any other natural resource, it is necessary to understand the full extraction process in order to really appreciate the asset.
A Balanced Tin Supply. World tin production has been quite stable in recent years, with refined tin production between roughly 330,000 tpy and 370,000 tpy. This is made up from mine production between 270,000 tpy and 310,000 tpy, and the balance by 50,000 – 70,000 tpy of secondary refined tin production.
A new study found that mining caused nearly 10 percent of deforestation in the Brazilian Amazon between 2005 and 2015, not the 1-2 percent assumed by past assessments.
