14.3 Mining and mineral processing | The lithosphere

A reducing agent is usually added and the mineral is removed using chemical reactions. In modern times several new techniques are used to extract the mineral from the ore, in addition to smelting. The most common methods are flotation, leaching and use of redox reactions. Leaching involves mixing the ore with a carefully chosen liquid that ...

7.6: Classifying Separation Techniques

Changes in Chemical State. Distillation, sublimation, and recrystallization use a change in physical state to effect a separation. Chemical reactivity also is a useful tool for separating analytes and interferents. For example, we can separate SiO 2 from a sample by reacting it with HF to form SiF 4.

Heap Leaching

Heap leaching is an industrial mining process of separating precious metals, copper, and other minerals, from ores. It involves a series of chemical processes, through which the mineral ores are piled into the form of a heap, and a leach solution is spread over the ore surface to leach metal from the heap.

Chemical Properties of Minerals

For example, the mineral Aurichalcite, which has a chemical formula of (Zn,Cu) 5 (CO 3) 2 (OH) 6 contains an unspecific varying amount of zinc (Zn) and copper (Cu). This is indicated by comma separating the Zn from the Cu. If a chemical formula with two elements in parenthesis is separated by a comma, the number of those elements vary.

3.3: Formation of Minerals

The most common mineral precipitated by organisms is calcite, or calcium carbonate (CaCO3). Calcite is often precipitated by organisms as a polymorph called aragonite. Polymorphs are crystals with the same chemical formula but different crystal structures. Marine invertebrates such as corals and clams precipitate aragonite or calcite for their ...

SEPARATION TECHNIQUES

Separating the solvent from a solution – simple distillation Simple distillation is a method for separating the solvent from a solution. • For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
