How do you separate a mineral from a rock Answers

That depends on what kind of mineral and what kind of rock. If there is a difference between the density, i.e. the weight, of the mineral and rock, then you finely crush the rock and use 'flotation'.

Copper extraction Wikipedia

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

What is Concentration of Ore? Definition and Methods

The concentration of Ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. In this content definition and methods for the concentration of ore are explained along with the definition of ore and its types.

What is Gold Extraction? (with pictures)

Apr 03, 2020· Various mineral processing methods are used, often in conjunction with one another, to extract the ore from its rock encasement. Comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. Comminution is often one of the first steps in gold extraction. Extractors break apart the hard rock containing the ore.

Copper Mining and Extraction Sulfide Ores

Copper Mining and Extraction: Sulfide Ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated.

PROCESS AND APPARATUS FOR SEPARATION OF MINERAL ORE

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Methods of Gold Mining Geology In

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers.
