In the field of mineral processing, the successful flotation of target minerals requires sufficient liberation through grinding. The aim of this paper is to compare and evaluate the performance of ball versus short …
Tiny air bubbles are injected into the tanks (called flotation cells) which attach to the waxed phosphate particles (the water-repelling particles are pushed out of the water into the bubbles). The air bubbles rise with the phosphate to the top of the flotation cell where the valuable froth is skimmed from the surface and collected.
Efforts to concentrate high-dolomite Flor ida phosphate ores by flotation, using conventional fatty-acid/fuel-oil flotation [Liewellyn, 1982], showed that sodium silicate
The flotation results indicated that, when sodium oleate (NaOl) was used as the collector, HEDP displayed an outstanding depression effect on the dolomite flotation, whereas it had only a slight ...

The technical-grade single-mineral samples were ground and sieved to −105 + 38 μm prior to be used in the micro-flotation experiments.In addition, in order to perform spectroscopy studies, a portion of each single mineral was further ground down to an average size <5 μm using an agate mortar to increase mineral surface areas.The …
The separation of magnesite from dolomite was studied by flotation tests, X-ray photoelectron spectroscopy (XPS), and zeta potential measurements in the presence of calcium ion (Ca2+) dissolved from dolomite. Sodium oleate (NaOL) was used as collector, and sodium carbonate (Na2CO3) and sodium hexametaphosphate (SH) were used as regulators. …
The Bateman otation mechanism was developed in. S 1993 and is presently marketed by the Bateman Pro-cess Equipment Limited. The BQR series of Bateman cells have a round tank …
The separation of magnesite and dolomite has always been a difficult problem in flotation production, one of the reasons is that the dissolved Ca 2+ ions from dolomite weaken the anionic flotation selectivity. In this study, an ion-tolerance collector, sodium fatty alcohol polyoxyethylene ether sulfonate (AESNa), was used to weaken or eliminate the adverse …

Feldspar occurs in the pegmatite rocks and are associated with quartz and muscovite near the top of the granite (Fig. 1) (Pollet-Villard et al., 2017, Simmons et al., 2016, Swanson and Veal, 2012).The feldspar storage is approximately 10 billion tons worldwide, mainly occurring in North America, Europe, and East Asia (Zhang, 2013).Take for example a typical …
In a typical plant, the mechanical cell tanks are arrangedinaseriescalledabank.Thenumberofcells in a bank varies depending on cell size, application and plant circuit conRguration. The tailings from the Rrst cell move on as the feed to the second cell and so on and the tailings from the last cell form the Rnal tailings of the bank.
What is dolomite. The main components of dolomite ore are calcium carbonate and magnesium carbonate. They are carbonate minerals, including ankerite and manganese dolomite. Dolomite has surface adsorption, can provide a source of magnesium and calcium, has high refractoriness, a large specific surface area, and good heat insulation and heat …
