Crushing / grinding -> flotation / dewatering / draining -> copper concentrate and molybdenum concentrate. Production of refined copper: Dump-leaching -> SX-EW -> Refined copper
This requires understanding relationships between crushing, grinding and subsequent separation. In flotation, recovery of the valuable mineral generally falls in the coarser particle size ranges (Figure 1), which results in lower recovery at coarser grinds.
· In the process of crushing waste concrete, according to the working principle of more crushing and less grinding, it is necessary to carefully configure the concrete crusher equipment. Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing.

Crushing and grinding transform ore size into fine sand in order to release particles containing copper and gold. Flotation is a separation process to produce copper-gold concentrate. Concentrate slurry consisting of finely ground ore and water mixed with reagents is introduced into a series of mixing tanks called flotation cells, where air is pumped into the slurry.
Crusher equipment is some of the rarer equipment to have. There are different types of crusher equipment that serves different purposes. The different equipment is used to cut various materials depending on their hardness, moisture content, and reduction ratio.
