Optimization of High-grade Fluorspar Recovery from Rare Earth Element Carbonatite Deposit Using Column Flotation
Flotation machines and columns are engineered to maximize the recovery of desired ore grade in various minerals processing applications.
We use flotation process as our main technology in our extraction plant. Flota-tion process is suitable for refractory fluorite with complex mineral properties such as the ore mineral content with high mud, impurity and fluorite symbiosis, and useful mineral with disseminated fine grain size, etc. Similar to other sim-ilar mineral flotation equipment, the fluorite …

The main methods of fluorspar beneficiation include crushing, grinding, flotation and gravity separation. Each step in the process plays a vital role in separating fluorspar from impurities such as quartz, calcite and barite. Next, we mainly introduce four common types of fluorspar mineral processing methods, including quartz-type fluorspar …
After an initial flotation step to produce feed, the fluorspar purification process consisted of four steps. Firstly, a magnetic separation step was conducted to pre-concentrate the fluorspar into a non-magnetic fraction, while concentrating Fe- and REE-bearing minerals in the magnetic fraction.
