Reduction of Metals Extraction from Ore - A-Level Chemistry

Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised.

P. Doyle, in Encyclopedia of Geology, 2005. Environmental Impacts of Mineral Extraction. The environmental impacts of mineral extraction vary according to the type of mineral and the extent of its deposit, with impacts varying throughout the working life of a mine or quarry, and with the issues often continuing long after the deposits worked are no longer economically viable.

Ores and Minerals - Introduction, Extraction, Concentration ...

Minerals are naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color and hardness. For example, copper pyrite CuFeS 2 , calamine ZnCO 3 etc. are minerals. A mineral from which metal can be economically extracted in a maximum amount is called an ore.

An Introduction to the Chemistry of Metal Extraction ...

Aluminum, for example, is the most common metal in the Earth& 39;s crust, occurring in all sorts of minerals. However, it isn& 39;t economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide.

Mineral Chemistry - Tulane University

Minerals can form by any of the following processes: Precipitation from a fluid like H 2 O or CO 2.This can take place within the Earth by hydrothermal processes, diagenesis, and metamorphism, and at or near the Earth& 39;s surface as a result of evaporation, weathering, or biological activity.

General Principle of Extraction of Metals, Minerals, Ores ...

The minerals from which the metals can be economically and conveniently extracted are called ores. All the ores are also minerals but all minerals cannot be ores. i.e. both clay Al 2 O 3.2SiO 2.2H 2 O and bauxite Al 2 O 3. 2H 2 O are minerals of aluminium. It is bauxite that is used for extraction of aluminium and not clay.

Extraction of Resources Geology

The extraction of target minerals by this technique requires that they be soluble, e.g., potash, potassium chloride, sodium chloride, sodium sulfate, which dissolve in water. Some minerals, such as copper minerals and uranium oxide, require acid or carbonate solutions to dissolve.

TOPIC EIGHT EXTRACTION OF METALS CHEMISTRY FORM THREE

To extract ores containing minerals, a chemical reaction must be used to separate the metal from other elements. The choice of the best method for extraction of a metal from its ore depends on the chemical reactivity of the metal to be extracted. Most ores contain metal oxides. To extract the metal, oxygen must be removed from it.

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to be worth mining.
