Abstract 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.

Fluorite Processing Solution - Mineral Processing

Fluorite ore can be sorted by means of gravity separation and flotation. When the raw ore is coarse-grained fluorite ore, a gravity separation process can be used. The flotation process can be used when the raw ore has a high mud content, is accompanied by impurity minerals, or the useful minerals are inlaid with a fine particle size.

Feb 04, 2021  Fluorite is an important non-metallic mineral resource and the main source of fluorine in the industry. There are three kinds of processing processes of fluorite: hand separation, gravity separation and flotation separation. Among them, hand separation and gravity separation are mostly used as auxiliary separation and pre-separation, while flotation separation is the main method.

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 information on the separation is available. In this study, a novel reagent schedule using citric acid ...
