Copper is one of the few materials that does not degrade or lose its chemical and physical properties during the recycling process. Recycling has the potential to extend the use of resources and minimize waste. The International Copper Study Group estimated that 33% of the world's copper consumption came from recycled copper in 2017. Canada maintains a strong copper recycling industry ...

The concentration of cerium, the most abundant rare earth, is approximately the same as that of copper although the other REEs are much rarer. However, REEs are not usually concentrated in ore deposits in amounts that can be easily or economically mined (Long, 2010).

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the mostused metal in the world.

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purifiion, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which ...

 · Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat. After the ore has been concentrated it must be roasted to a high temperature allowing for the desired metal to be oxidized. Once the metal is oxidized it is reduced by a reducing agent. Reduction may require the metal oxide to be heated at a high temperature ...

Concentration or Dressing of the Ore Generally, the ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores ...
