The strong contamination of the interface is the main problem that results in low flotation efficiency of sphalerite in cyanide tailings. However, the consumption of cyanide and dissolved oxygen, as well as the concentration of ions including Zn2+ and SCN− in the leaching solution, decreased with the use of ceramic ball medium. The conclusions …Web

The results showed that grinding time had a significant inversed influence with the product fineness for both pellets at the laboratory scale. For the industrial scale, the aspired fineness of ≤ 30 % residue at a mesh size of 1.0 mm was obtained with a classifier. Moreover, power consumption decreased when increasing the discharge orifice width.Web

The classifier, when open, acts as a pump drawing slurry axially along the mill. It enters the classifier through the holes in its end plate and is then forced radially outward by rotational acceleration of the classifier cage. The enhanced outflow significantly strengthens the large toroidal vortices on the outside of the classifier.Web
