The d-block elements are divided into the first transition series (the elements Sc through Cu), the second transition series (the elements Y through Ag), and the third transition series (the element La and the elements Hf through Au). Actinium, Ac, is the first member of the fourth transition series, which also includes Rf through Rg.. The f-block elements are the elements Ce through Lu, which ...

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 …

Titanium extraction. The overall process. Titanium is extracted from its ore, rutile - TiO 2. It is first converted into titanium(IV) chloride, which is then reduced to titanium using either magnesium or sodium. Conversion of TiO 2 into TiCl 4. The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about ...

Dec 06, 2019· Extraction of metals from their natural sources is basicallya broad term which includes several steps in it. These steps start from exploraton of metal reservoirs to final refining of metals. Major factors involved in deciding all these processes are low cost and phhysical properties of metal to be extracted.These Steps are explained one by one ...
