fluorite flotation from carbonate ores

Enrichment of Molybdenum and Fluorite by Flotation of ...

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
