Calcite is a semi-soluble mineral that can be considered one of the main problematic
gangue phases for several different types of valuable sulfides and oxides. Since froth …

The article presents the results of generalization of known information on various methods of
enrichment of low-grade phosphate raw materials in the world. Based on the review of …

Flotation separation of apatite from calcite is difficult due to their same activate calcium
atoms on the surface. To address this issue, amino trimethylene phosphonic acid (ATMP) …

Sodium hexametaphosphate (SHMP), as a common flotation agent, is widely used in
various mineral processing. In this study, effects of SHMP on the flotation of fine apatite and …

The flotation response of collophane and dolomite using β-naphthyl sulfonate formaldehyde
condensate (NSFC) as depressant has been investigated through micro-flotation and batch …

To address the flotation separation problem between apatite and dolomite, DMNS (disodium
methylenebis naphthalene sulfonate) was selected as a depressant in this research. Micro …

In the phosphate industry, the use of certain flotation reagents can cause severe water
pollution and have a negative effect on the environment and human health. Therefore, the …

A preliminary study was conducted on the Hallimond tube to find routes for the direct
flotation of fluorapatite. Carboxymethylcellulose-sodium oleate and sodium alginate-sodium …

This preliminary study explored a novel approach to enriching unexploited low-grade
phosphate washing sludge (PS) using a combination of attrition scrubbing, desliming, and …

Recently, many research efforts have been made to reduce the magnesium content in the
phosphate concentrate to meet the requirement for phosphoric acid production and other …
