Over 95% of all acid grade fluorspar is processed by flotation through Sub-A (Fluorspar Type) Flotation machines. These machines, of the cell to cell type, are designed special for fluorspar with a high degree of flexibility essential for selectivity and multiple cleaning of concentrate.
Feb 13, 2021· Over 95% of all acid grade fluorspar is processed by flotation through Sub-A (Fluorspar Type) Flotation machines. These machines, of the cell to cell type, are designed special for fluorspar with a high degree of flexibility essential for
Reverse cationic flotation batch tests were conducted using 1kg of fluorspar tailings in 2.5l Denver D12 flotation cell at pulp density of 40% solids, impeller speed of 1000rpm and air flowrate of 60%. Before flotation, the pulp was first conditioned with starch for 4min and then conditioned with collector for 4min.
The sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite (fluorspar) concentrate.
Fluorite flotation: please anybody suggest good depressants for silica and calcite in fluorite flotation.My specs are now: Raw fluorspar has CaF2 =60%, CaCO3=19.5% and SiO2=9.7%, I am already using water glass, pH=10, with oleac acid
Fluorspar / Fluorite Mineral Flotation Fluorspar (also referred to as fluorite) is a mineral composed of calcium fluoride, CaF 2. It is a naturally occurring mineral that tends to form in rocks that have been subjected to hydrothermal activity.
Apr 24, 2019· 1 Description of fluorite Fluorite (also called fluorspar) is a mineral that common in nature, consists mainly of calcium fluoride (CaF2), can be symbiotic with many other minerals.
Apr 01, 2021· Finally, the most widely seen fluorite-flotation cases, including separation of fluorite from quartz, calcite, barite, and sulfide, are summarized individually. The present review sheds new light on the deep understanding of fluorite flotation, the future synthesis of reagents, as well as their schemes in practical use.
Flotation tests showed that the best results in terms of fluorite metallurgical recovery were 82.8% and 87.9% for new collectors DP-I and DP-II respectively, for a dosage of 100 g/t and using pneumatic cell. Additionally, in terms of fluorite grade, DP-I showed the best results, achieving 79.7% of CaF2 in roughing step for a dosage of 100 g/t.
Aug 01, 2000· Abstract The amenability of column flotation for the beneficiation of fluorspar was investigated, and the overall performance of the column flotation was compared to the performance of the existing conventional flotation cells at the plant. It was established that improved grades and recoveries could be obtained by adopting column technology.
