Processes of iron and tin extractions from their ores

Update date: May 24

[Introduction]: The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore is gravity separation.However, all kinds of iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation

    Feb 15, 2021 The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres

    Dec 20, 2012 Extraction of Iron. Iron is extracted from its ore, that is hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ) through reduction by carbon in the form of carbon in a blast furnace. The mixture of iron ore, carbon, and limestone is entered into a blast furnace through the top of the furnace. Hot air is then put in through the lower part of the furnace

    iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is

Because of their reactive tendencies, the majority of the elements are not found in the free state. Metals found in combination include potassium, sodium, calcium, magnesium, aluminium, zinc, iron, lead, etc. Minerals are the natural materials found on Earth that contain metals and their compounds

    The methods chiefly used for the extraction of lead and tin from their ores are respectively self reduction and carbon reduction. Self reduction for lead is as follows. 2 P b S + 3 O 2 → 2 P b O + 2 S O 2 ↑ P b S + 2 O 2 → P b S O 4 2 P b O + P b S → 3 P b + S O 2 ↑ P b S O 4 + P b S → 2 P b + 2 S O 2 ↑ Carbon reduction for tin is

Concentration of Ores: Ores may be concentrated either by (i) Washing away the earthy materials in a stream of water in order to leave behind the heavier ores as is the case with tin ore or by (ii) Froth flotation where the ores are churned up with oil and water to form froth. This froth which contains the ore is skimmed off by blowing air
