The quartz and silicate gangue minerals found in the fluorite ore in the alkaline medium, which is usually the fluorite flotation medium, are highly negative in surface charge [4–6]. Therefore, used anionic collectors cannot be physically adsorbed on the surface of fluorite particles, which helps to arrest this mineral [ 7 – 10 ].

molybdenum and fluorite separately reduce flotation yield [5]. Flotation tests on fluorite ores with various carbonate content (CaCO3 contents from 4.43% to 74.40%) were carried out using acidized sodium silicate as modifier and oleic acid as collector. A high purity fluorite concentrate (99% CaF2) was obtained. It was demonstrated that acidized

Fluorite melts easily and is used as a flux in the smelting of metallic ores. A 'flux' is a material used to help remove impurities from ore as it is refined into metal. As such, large amounts of fluorite are extensively used in open-hearth steel and steel enamelware production, the smelting of aluminum, as well as lead and antimony refining.

Fluorite is considered to be one of most popular minerals in the world among gem and mineral collectors, second only to quartz. It is often referred to as ' the most colorful mineral in the world ' owing to its variety of brilliant colors. Fluorite was first described in 1530 and was originally referred to as 'fluorspar'.

Laboratory tests by Li et al. on a fluorite ore from Hebei (China) revealed that an increase in temperature from 13°C to 27°C considerably improved flotation performance (10% recovery increase), which was accompanied by a slight grade decrease of 0.8% . A similar effect was found in tests which varied the oleic acid collector dosage.
