The utilization of citric acid as a depressant for the flotation

2020. 9. 1.· To achieve the efficient flotation separation of barite from fluorite, citric acid (CA) was utilized as a depressant for fluorite in this study. Microflotation showed that both fluorite and barite had good floatability when using sodium oleate (NaOl) as the collector, while fluorite was selectively depressed when using CA as the depressant.

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

This study presents a highly selective reagent system that utilizes sodium hexametaphosphate (SHMP) to improve the separation of scheelite from calcite and fluorite using an anionic–nonionic collector. The recoveries of calcite and fluorite decreased to 20% as the SHMP dose exceeded 6 × 10−6 mol/L, whereas that of scheelite remained at 85%.
