Dissolved iron (II) sulfate FeSO 4 5 H 2 O is separated from the leaching solution, some of which is sent to sewage treatment plants as a phosphate precipitant. After separation, TiO 2 is fired at 1200 ° C in rotary kilns. It is then either processed further as a brilliant white color pigment or converted into titanium tetrachloride using charcoal, in the presence of chlorine.

Sulfuric acid is considered a very strong and cheap acid. Most of it is used to break down minerals. This means the conversion of the generally very poorly soluble minerals into a substance from which the element or the desired compound can be more easily isolated. Extraction of raw titanium Titanium ores are primarily the Continue reading Leaching of minerals using sulfuric acid

2021-4-1 The dissolution of copper oxide mineral, malachite (Cu 2 (OH) 2 CO 3), by sulphuric acid can be expressed as follows (1) Cu 2 (OH) 2 CO 3 + 2H 2 SO 4 → 2CuSO 4 + CO 2 + 3H 2 O. The leaching of oxide and sulphide minerals is important in a wide range of fields, including minerals processing, hydrometallurgy, materials science and geochemistry.

2016-4-14 ACID SUPPLY. The source of sulphuric acid for leaching is usually a major consideration for small plants. If the plant is located in an area where acid can be purchased at low cost, one of the greater items of capital expense can be avoided. For most plants the acid must be produced.
