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.

19.1 Occurrence, Preparation, and Properties of
Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–11 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
