Sulfate minerals have graduallye the main gangue minerals of fluorite deposits, and the flotation separation of fluorite and sulfate minerals is difficultmonly used depressants. In this paper, the high selectivity of a novel depressant sodium polynaphthalene formaldehyde sulfonate SPS for the flotation separation of fluorite
The separation of calcite from fluorite and barite in a mixed mineral pulp can be achieved by floating fluorite and barite, with >4 × 10 4 g/L valonea extract to depress calcite flotation, leaving the calcite in the tailings.
Fluorite CaF2, as an important strategic mineral source, is usually separated from calcite bymon froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1Hydroxyethylidene1,1diphosphonic acid HEDP or H4L is widely used as an environmentally friendly
For fluorite, the flotation recovery increased from 84.1 to 91.4 throughout the pH range studied. Meanwhile, the recovery of fluorite and calcite can reach 91.18 and 93.84 respectively at pH 9.0, which indicated that the effective separation of the two minerals cannot be realized only by adjusting pulp pH.
Magnetic separationmonly used to separateic minerals such as fluorite and quartz fromic minerals such as siderite, and fromic minerals such as monazite, bastnaesite and xenotime Gupta and Krishnamurthy, 1992, Habashi, 2013.
Fluorite CaF2, as an important strategic mineral source, is usually separated from calcite bymon froth flotation method, but this separation is still not selective enough.
Nonetheless, bastnäsite is often associated with calciumbearing gangue minerals such as fluorite, and the separation of bastnäsite from fluorite by flotation is usually difficult due to their similar surface properties and floatability Pradip and Fuerstenau, 1983, Pradip and Fuerstenau, 1991, Zhang et al., 2013. Bastnäsite and fluorite
2. Separation of fluorite and barite The ore type of a fluorite ore dressing plant is fluoritebarite type, the main minerals are fluorite and barite, and the gangue minerals are quartz and calcite. The specific fluorite ore beneficiation process is as follows one roughing, one sweeping, and three flotation processes.
Scheelite and fluorite are important industrial minerals used as raw materials to produce spaceflight items, catalysts, ceramics, optical glass, and fine chemicals .However, Flotation separation of scheelite from fluorite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics such as solubility, hardness, specific gravity, and PZC
Fluorite is one ofmon nonmetallic minerals, also known as fluorspar. Its chemical formula is CaF2. It has rich colors and is widely used in metallurgy, chemical industry, ceramics, glass and foundry industries. Common fluorite beneficiation methods mainly include manual selection, gravity separation and flotation.
