Solvometallurgy: An Emerging Branch of Extractive Metallurgy

Apr 19, · This position paper introduces the reader to the concept of solvometallurgy, the term used to describe the extraction of metals from ores, industrial process residues, production scrap, and urban waste using non-aqueous solutions. Here, non-aqueous is not used to imply anhydrous, but rather a low water content. The unit operations are as follows: solvent leaching; separation of the residue

Extraction of Nickel, Cobalt and Iron from Laterite Ores

Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte.

Ore: The mineral from which a metal can be readily and economically extracted on a large scale is said to be an ore. For example: Clay (Al 2 O 3. 2 SiO 2. 2 H 2 O) and bauxite (Al 2 O 3.2 H 2 O) are the two minerals of aluminium, but aluminium can be profitably extracted only from bauxite. Hence, bauxite is an ore of aluminium and clay is its

How Do We Extract And Process Ores In Three Steps - Minerallurgy

How to process the mineral to extract metals; metallurgy. The extraction of the metal depends on the chemical nature of the ore. For example, for sulfides like blend or galena, we start by burning the concentrate, which then turns into oxides. The gases burned are then made of sulfur oxide; they pass through water to obtain sulfuric acid. The oxidized ores pass through blast furnaces, abandoning their oxygen. At the bottom of the blast furnaces, we get liquid metals.
