For the separation of the metal cobalt from raw ore to cobalt concentrate, there are four stages,  “crushing – grinding – flotation – drying.”

1. Cobalt ore crushing
In the crushing stage of cobalt ore, we need two stages of crushing to crush large pieces of raw ore into particles with a size of tens of millimeters for the next step of work.

2. Cobalt ore grinding
The finely crushed ore particles do not meet the flotation requirements, and the ore particles need to be further crushed before flotation. A ball mill grinds the coarse-grained ore and classifies it using a spiral classifier. The qualified ore particles enter the next flotation stage, and the unqualified ore particles are re-sent to the ball mill for grinding until they are qualified.

3. Cobalt ore flotation

After grinding, the qualified cobalt ore powder is sent to the flotation machine for flotation, and a suitable collector agent is added to obtain high-grade cobalt concentrate.

4. Cobalt ore drying

The cobalt concentrate recovered by flotation contains a certain amount of water. It can not sale immediately or put into the next step of production before drying.
