What is metal processing?
Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling.
The method used to extract a given metal from its ore depends upon the reactivity of the metal and so how stable the ore is. In each case, the metal ion in the compound gains electrons, ie they...
Metal ores are naturally occurring rocks that contain metals or metal compounds in sufficient amounts to make it worthwhile extracting them. The method used to extract a given metal from its ore...

Earth’s crust is the storehouse of metals such as sulphur, silicon. Some of the major metals are also found in seawater such as chloride. They are present in a free state as well as a combined state. For example, gold and platinum are available in a free state whereas calcium and copper are available in combined states. The metals found in the free...
Given below are the types of ores with their examples- 1. Oxide Ores- In this particular ore, the metals are present in the oxidised form. Obtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium) 1. Sulphide Ores- In this particular ore, the metals are present in the sulphide form. Since it is di...
We all know that the metals exist mostly in the form of salts along with other minerals to form an ore. These impurities should be removed with the help of different inorganic separation techniques. Every step takes us to a purer content of metal in the ore. In this concept page, every process involved in the extraction of metals will be discussed ...
Iron, which is one of the most important and beneficial metals, is extracted from iron ores. Iron ores mines are found in Goa, Karnataka, Orissa.Aluminium is extracted from Bauxite ore. In India, the most available ore is Bauxite ore. States with Bauxite deposits are Maharashtra, Tamil Nadu and Gujarat.Tin which is obtained from tinstone can be found in Jharkhand.Metals are extracted from the ores because of their properties. They can be used in different areas and can benefit humankind. Following are the uses of metals in our day-to-day lives.Metals are useful for the production of vehicles and their parts. This means that metals play an important role in transportation.Since they are malleable and ductile, they can be hammered to get different shapes and also can be drawn into wires.Electronic devices such as computers and household devices such as ovens, microwaves are made with the help of metals.Concentration. The desired metal is usually present in the ore with other minerals. Concentration techniques are employed to separate the valuable metal from the rest of the ore. For example, froth flotation, gravity separation, and magnetic separation.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Liquation is a metallurgical method for separating metals from an ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected.
