##tihuan2##The demand for copper is ever-increasing, playing a critical role in the transition to a clean-energy economy. By the early 21st century, most of the rich copper oxide ores had already been mined out, leaving current deposits with a grade sometimes less than the tailings of earlier mining [1,2].A study conducted by Calvo et al. [] revealed …

##tihuan2##Spiral Classifier Working Principle The grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank.
