How do we extract minerals? - USGS

Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth’s surface. In a surface mine, hard rock must be drilled ...

What Is Involved in Processing Raw Materials? (with pictures)

Feb 21, 2021  The process used in converting raw metals like iron ore into steel involves beneficiation, or crushing and separation, and smelting, the process of heating the ore to obtain the pure metal. Processing of raw materials like trees may involve an entirely different process.

Processes and Procedures in the Extraction of Iron ...

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Jul 28, 2012  The denser ore particles settle down in the grooves and lighter gangue particles are washed down by water. b) Magnetic Separation. The Principle of magnetic separation is magnetic properties of the ores. In this process, the crushed ore is placed over a conveyer belt, which rotates around two metal wheels, one of which is magnetic.

Sep 06, 2019  The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.
