mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density. The underflow from the cyclones is sent back to the mill to be reduced further in size, generally from 75 to 200 microns, with further regrinding in some cases to improve the liberation of desirable
Copper production About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]). This type of flow sheet is usually followed when the crude ore contains below 30% iron. The number of steps involved in crushing and grinding depends on various factors such as the hardness of the ore and the level of impurities present [ 5 ].
Copper Layer: Depending on the board type, this layer can either be copper foil or a fullon copper coating. Regardless of which approach is used, the point of the copper is still the same — to carry electrical signals to and from the PCB, much like your nervous system carries signals between your brain and your muscles.

Copper recovery is achieved with multistage flotation technology with regrinding of middling products. Molybdenum recovered with the copper concentrate is separated in a multistage molybdenum flotation circuit. Nominal copper and molybdenum concentrate production is approximately 2,400 and 15 tonnes per day, respectively.
