In mining operations the desired mineral from which a metal is to be extracted often constitute only a few percent of the material is mined.Thus it is necessary to separate the desired ore from waste rock before proceeding with other metallurgical operations.A verity of devices including cyclone separators,inclined vibrating tables,and floatation tanks are employed.

What do you call a rock that contain s a high concentration of valuable mineral?
it is called an ore
Calculate the mass of alumina produced from two moles of the ore?
The concentration of alumina in the ore is necessary; also the effective yield.
What is concentration of ores called?
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal. Ores are mined from deep within the earth's crust in the form of rocks. The minerals are embedded in these rocks. The rocks are first crushed into smaller pieces by crushers. Then they are ground to powder by ball mill and other processes so that powdered ore is obtained. Depending on the type of ore, hydraulic washing, froth floatation process, magnetic separation and chemical separation techniques are applied for concentrating an ore.
How do you get copper metal from copper ore?
It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.
The minimum concentration factor necessary for profitable mining of an ore deposit depends on?
The Minimum Concentration Factor (MCF) depends on the minimum % for exploration. This means the minimum % of valuable ore needed to make mining profitable. For a mine to be profitable it needs to take in enough profit to pay for the amount of money needed for energy to retrieve ore and pay for all other costs related to mining (machinery, land costs, employees, etc). The minimum % for exploration divided by the % percent in the crust yields the MCF. This value is very low for ore that are plentiful and easy to obtain, and get progressively higher for ore that are harder to mine and are not as plentiful in the crust.
Why pre-concentration of ore is carried out?

it is called an ore
A mineral is classified as an ore as long as?
It is considered an ore as long as the locallized concentration of the mineral exceeds its crustal abondance.
An ore contains 2.88g of silver per ton of ore What is the concentration of silver in ppm?
The answer for sure is 3.17 ppm
What is the concentration of copper in copper ore?
Typically about 0.5% to 2%.
What cargo is carried on the St Lawrence?
Generally Iron Ore.
Calculate the mass of alumina produced from two moles of the ore?
The concentration of alumina in the ore is necessary; also the effective yield.
A mineral is classified as an ore as long as what?
A mineral is generally classified as an ore, if its locallized concentration far exceeds its crustal abundance.
What is the amount of a substance in a given quantity of a mixture solution or ore?
concentration
What is the amount of a substance in a given quantity mixture or ore called?
the answer to that is concentration!!
Why is it hard to extract a metal from its ore?
The ore contain frequently the metal in a compound and also have many impurities. The concentration of the metal is generally low.
Why titration with standard hard water is carried out?
To determine concentration of EDTA.
