It is worth noting that 45% of the copper in Chile is exported as a copper concentrate. Currently, some copper mining processing plants use the fossil-fuel dryer to reduce the humidity of the copper concentrate. It is possible to use concentrating solar power for drying copper concentrate since the operating temperature of the drying …
Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%. Production Process ... Copper concentrate is smelted and converted to metallic copper, which allows it to attain forms that can be submitted to further refining, more than 99% pure, as in copper anode and copper blister. ...
In copper smelting, obtaining uniform blend compositions from diverse copper concentrates is vital for stable and economical operation, keeping in mind the decreasing quality of raw material with time. The concentrates differ in chemical compositions and contain around 24 critical elements, making it challenging to achieve …
Development of the Dryers S.L Chen and H. Mansikkaviita Kumera Corporation, Technology Center, Riihimäki, Finland Keywords: copper, concentrate drying, steam dryer, dryers Abstract – By placing additional demands on energy and gas flow, the moisture content of a copper concentrate has an adverse effect on the smelting process.
2) Copper concentrate filtration is the operation of making the ore slurry pass through a water-permeable and impermeable spacer layer of solid particles to achieve solid-liquid separation. Filtration is a further …

Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace …
In primary copper smelters, the received copper concentrate and other materials contain a certain amount of moisture, ranging from six to 14 per cent. Moisture in wet concentrate has a negative effect on the performance of the smelting furnaces when it is fed directly to the furnaces, namely increasing the energy consumption and the off …
