Cassiterite is the primary mineral ore for tin, and is found in hydrothermal and igneous veins, and importantly in the Democratic Republic of the Congo, in alluvial placer deposits. The new market for Cassiterite has come from the electronics industry, in which a new demand for leadfree solder materials has led to the use of solder materials with a much higher proportion of tin.

· The Democratic Republic of Congo (DRC) is a country with huge natural wealth. Almost every valuable natural resource can be found there, from a multitude of minerals – including diamonds, gold, copper, cobalt, cassiterite (tin ore) and coltan – to timber and oil. But this vast natural wealth has brought nothing but suffering and misery to the Congolese people.
[Introduction]: The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore is gravity, all kinds of iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation.

· Prior to becoming the DRC, Zaire, or even the Belgian Congo, it was the Congo Free State (CFS) – the personal colony of King Leopold II of Belgium. Leopold designated large parts of the CFS as concessions to private companies (see Figure 1) in which he was the primary stakeholder. These private companies extracted natural resources through extreme violence and by coopting the powers of ...
