Ore Dressing Equipment for Celestite

The main component of celestite is strontium sulfate. Celestite is used to produce strontium carbonate and CRT glass for TV. Its colors can be blue, green, yellow, orange, light blue, gray, or colorless sometimes. As a mineral resource, lapis lazuli is often symbiotic with other gangue, leading to failed celestite grade in industrial production, so most of the celestite ore need beneficiation process before industrial production, then what ore dressing equipment used for celestite ore beneficiation?

We need to know the properties of celestite before getting the right beneficiation methods or equipment. Strontium sulfate has good natural floatability and proportion is 3.9-4.0, exist in associated with carbonate and gypsum, coarse-grained disseminated, there are also finely disseminated celestite. So the Celestine ore dressing methods can be gravity separation and flotation.

Gravity separation is based on the different proportion betweent celestite and gangue. The gravity separation is a good choice because of the coarse-grained dissemination and larger gravity proportion than gangue proportion. Commonly used celestite ore dressing is jig concentrator, which can effectively separate coarse, medium and fine-grained celestite ore with good dressing effect, small investment, low production costs. It is an ideal ore dressing equipment for coarse celestite ore.

Flotation method is based on the different flotability between strontium sulfate and gangue. Strontium sulfate has good floatability, so it is easy to separate it with the pharmaceutical and flotation machine. However, it needs big equipment investment, high production cost and it brings chemical pollution to the environment. Celestite flotation machine includes crusher, ball mill, classifier, mixing bucket, flotation machine, filter press, dryer, etc.
