Of the iron ore exported % of the volume was iron ore pellets with a value of billion and % was iron ore concentrates with a value of billion. The majority of Canada's iron ore comes from Nunavut and from Labrador along the Quebec and Newfoundland and Labrador border.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only % to % copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper .

of gold made naturally by gravity concentration due to ore particles being transported by water. Mechanical concentration is used to continue the process until sufficient concentration is obtained. Gravity concentration works when gold is in a free elemental state in particles large enough to allow mechanical concentration to occur.

For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few onehundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small .

Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two decades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leachingsolvent extractionelectrowinning, the basic methods ...

Fresh water consumption at the concentrator plant is around 200 gallons/ton of ore. If recirculation is maximized, leaks are avoided, and evaporation is reduced, the water use may be ...

The average grade of copper ores in the 21st century is below % 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 .

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

After concentration is complete, the next phase in creating marketready copper is refining. That typically takes place away from the mines themselves at a refining plant or smelter. Through ...

The concentration of these minerals in an ore body is low. Typical copper ores contain from % Cu to 1 or 2% Cu. Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copperfromore is produced by concentration/smelting/ refining of sulfide ores.
