Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Several attempts have been done aiming to recover copper from flotation tailings through mainly acid leaching [17] and froth flotation [4] Using the latter the recovery of copper through reprocessing of tailings has been studied both in the laboratory and on the pilot scale with an emphasis on the concentration of reagents and a pre economic analysis [18]
