Molybdenum Ore Beneficiation Methods

The main beneficiation method for molybdenum ore is flotation, and the molybdenum mineral recovered by flotation is pyromorphite. The flotation chemicals use non-polar oils as trapping agents, and a foaming agent is added at the same time. In order to ensure the quality of molybdenum concentrate, it is sometimes necessary to further separate heavy metal minerals such as copper, lead, iron and calcium oxide and carbonaceous minerals contained in the molybdenum concentrate, such as the use of sodium sulfide, sodium hydrosulfide, cyanide or ferrocyanide to inhibit the copper and impurity content.

Flotation process of molybdenum concentrate

1,Molybdenum ore is crushed by jaw crusher firstly, and then the ore is crushed by fine jaw crusher to reasonable fineness and then sent to the bin by elevator.

2. The ore is evenly fed into the ball mill by the feeder, and then the ball mill grinds the ore.

3,After grinding, the ore fines enter the spiral classifier, the spiral milking machine with the help of solid particles of different specific gravity and thus the principle of different precipitation speed in the liquid, the ore mixture for washing and grading.

4, through the mixing barrel and sent to the flotation machine for selection. According to different mineral properties add different corresponding chemical agents, flotation machine in the dynamic collision of bubbles and ore particles and bubble particles combined with the static separation, so that the required minerals and other substances are separated, and is conducive to the separation of fine-grained or fine-grained molybdenum ore.

5, with high efficiency concentrator to remove the water in the mineral concentrate after flotation, up to the national standard.
