4 Summary Processing technology of middlings should be adapted to the mineral and petrographic properties of the processed ore. Therefore, in the case of Polish copper ores, which tend to produce large quantities of difficult to treat middlings, separate processing of these middlings should be preferred.

This research investigates the hydrometallurgical processing of molybdenum middlings extracted from copper-molybdenum ore in the Shatyrkul-Zhaysan cluster in Kazakhstan.

The molybdenum ore is a kind of sulphide ore, which generally exists in the form of molybdenite and has good floatability. The type of flotation machine applied is similar to that of copper ore and is dominated by the external pneumatic flotation machine. ... saving the froth pump required for return of middlings and making the whole process ...

Tin Ore Processing. ... Five Wilfleys treat the finer products from the battery, and the middlings of these, after a slight classification, pass on to two other Wilfleys. These tables make 220 ¾-inch strokes per minute, and treat 20 to 30 tons each per 24 hours. The revolving buddles make one revolution per minute, and yield a head, middle ...
