3.2.7 Extraction of Metals - Principles of metal extraction. A level chemistry AQA specification: 3.2.7 Extraction of Metals - Principles of metal extraction Very few metal ores occur in a pure enough form to be used directly in the extraction process. The first stage is to separate the useful ore from the rock.

Tin occurs in grains of the native metal but chiefly as stannic oxide, SnO 2, in the mineral cassiterite, the only tin mineral of commercial significance. The metal is obtained from cassiterite by reduction removal of the oxygen with coal or coke in smelting furnaces.

An ore is a compound or mixture from which an element can be extracted for commercial profit. Cassiterite has been mined for thousands of years as a source of tin. During ancient times, Europe obtained most of its tin from the British Isles. Today, the major producers of tin

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.

The next step is the extraction of the metal in the molten state, a process called smelting, which includes reduction of the metallic compound to the metal. Impurities may be removed by the addition of a compound that forms a slag—a substance with a low melting point that

Tin is also used as a plating to protect other metals such as lead, zinc, and steel from corrosion. Tin cans are actually steel cans covered with a plating of tin. Other applications for tin include metal alloys such as bronze and pewter, the production of glass using the Pilkington process, toothpaste, and in the manufacture of textiles.

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.

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 ...
