Flotation separation of fluorite from calcite using ...

Flotation separation of carbonate fluorite ore is a puzzle in mineral processing. In this study, the flotation separation of fluorite from calcite using polyaspartate (PASP) as depressant and sodium oleate (NaOL) as collector was investigated, and the adsorption mechanism was analyzed by zeta potential measurement and infrared spectrum (IR) analysis.

Lower temperature flotation of carbonate-fluorite ores ...

Aug 24, 2010 · The authors provide insight into the problem of selective flotation of fluorite from carbonate-fluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride provide rather high level of selectivity in fluoride flotation from poor high-carbonate ores and make it possible to eliminate high-temperature pulp treatment with acceptable reduction in the flotation ...

Investigation of the depressants involved in the selective flotation of scheelite from apatite, fluorite, and calcium silicates: Focus on the sodium silicate/sodium carbonate system

Investigation of the depressants involved in the selective ...

Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO 4) from fluorite, apatite, and silicates. Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult.

Selective Flotation of Calcite from Fluorite: A Novel ...

Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little ...

The authors provide insight into the problem of selective flotation of fluorite from carbonate-fluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride ...

Flotation Reagents - Mineral Processing & Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Summary of Fluorite Ore Flotation Process - JXSC Machine

Apr 24, 2019 · Flotation is a useful beneficiation method for fluorite/ fluorspar ores, suit for large scale fluorite ore processing plant, the flotation process and stone agent varies from the ore characteristics.

Reverse Flotation Separation of Fluorite from Calcite: A ...

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common 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. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly ...

US3893915A - Fluorspar ore flotation - Google Patents

Flotation of fluorite from calcareous gangue with a fatty acid collector in an aqueous alkaline ore pulp is improved by adding an alkali metal bisulfite salt or an alkali metal thiosulfate salt before adding the collector. US3893915A - Fluorspar ore flotation - Google Patents Fluorspar ore flotation ...

Fluorite - Wikipedia

Fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9,000 areas. It may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite.

Improving the finely disseminated carbonate-fluorite ore ...

The article presents experimental research into intensification of fine-disseminated carbonate-fluorite ore flotation by adding FLOTOL-7,9 agent. It is shown that the optimal agent modes allow the yield of the saleable fluorite product of above 90% CaF 2 grade at higher than 60% fluorite extraction.
