The purification process of talcum powder has a progression. Each process of talcum powder manufacturers needs to be processed in a standardized manner. For each aspect, attention should be paid during processing. The following are the five aspects mentioned. Let's take a look.

Many users don't know what the processing technologies for purifying talcum powder are. Today, the editor will introduce them to you:

Flotation:

The flotability of talcum powder is relatively good. Hydrocarbon oil collectors can be used for flotation. The commonly used collector is kerosene, and flotation oil is used as a foaming agent. The foam generated by methyl isobutyl carbinol is relatively brittle. Only one roughing, one scavenging, and 2 to 4 cleanings are required to obtain the final concentrate.

Manual selection:

According to the different smoothness of products and gangue minerals, workers make selections by hand. Because the product has better smoothness with higher grade, it can also be identified by feel.

Electrostatic separation:

Talc ore also contains some minerals such as magnesite, magnetite, pyrrhotite, and tremolite. The dissemination size is about 0.5mm. In an electrostatic field, talc has a negative charge and magnesite has a positive charge.

Magnetic separation:

Talcum powder has a certain purity. Due to the presence of stained iron minerals in the ore, magnetic separation is needed to remove iron minerals.

Photoelectric sorting:

Photoelectric sorting is a method of sorting based on the different surface optical properties of talc and impurity minerals. It includes ore bins, feeders, belt conveyors, radiation sources, detectors, etc. Then, the characteristic that talc emits white fluorescence under ultraviolet irradiation is used.
