What is Mineral Processing?
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores.
What is mineral processing engineering?
Mineral Processing Engineering deals with the extraction, separation, and concentration of minerals from raw ores. Extractive Metallurgy focuses on refining processes, such as pyrometallurgy, hydrometallurgy, and electrometallurgy, through which concentrates are refined into a pure metal form.

Frequently Asked Questions (FAQs).
Why is mineral processing important?
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.
How is the mineral processed?
The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals.
What are the steps in mineral processing after one extraction?
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.
What are the two types of minerals?
Minerals are also important for making enzymes and hormones. There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur.
What is done with the waste products from the processing of minerals?
Other waste rock (gangue) excavated from the ore body, and any coarse wastes separated during processing are stored in waste piles or in the base of tailings dam embankments. By far, the major fraction of mining waste such as waste rock are disposed of in heaps (or piles) at the source.
Where does mineral processing usually begin?
At the mining site. The acid and the metals it causes to leach from rock that seep into the ground water or enter streams or lakes as runoff.
What factors determine whether a mineral deposit is profitable to mine?
Among such factors are the shape of a deposit, its depth below the surface, its geographic remoteness, access to transportation, the political stability of the region, and market factors such as the price of the metal in world trade and the costs of borrowing the money needed to develop a mine.
What is concentration in mineral processing?
Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated.
What is recovery in mineral processing?
All mineral processing activities are subject to losses of the desired mineral, which may occur at all stages of processing. A plant has a Recovery which is the mass of product recovered for final disposal, divided by the mass contained in the ROM ore fed into the plant, expressed as a percentage.
What are the four main types of mineral processing?
- Gravity.
- Flotation.
- Chemical leaching.
- Magnetic and electrostatic.
What is the final step in mineral processing?
As a rule, comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral. Today, these processes are carried out in mechanized crushers and mills.
How does mineral processing degrades the land?
The mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust in the atmosphere. It retards the process of infiltration of water into the soil after it settles down on the land.
