This work describes the concentration of iron ore slimes on a pilot scale by using a 500mm diameter flotation column and a novel collector, which renders the use of a depressant unnecessary The pilot column was operated in series with the industrial plant Vargem Grande 2 (Iron Quadrangle, Brazil) receiving, as feed, part of the underflow from the desliming thickener
The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calciumbearing minerals To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, with salicylhydroxamic acid (SHA) as the

Cartridge Collector Model 2DCP4 and 2DCP12 Baghouse Model 1309PTHH1206 Another hazard in the mining and minerals industry is the large volume of dust being produced This dust is hard and abrasive, and with large volumes, it results in filters wearing out rapidly This leads to frequent maintenance and filter change outs on a dust collector

Cassiterite is the most common and important tinbearing mineral, and calcite, a primary gangue mineral is generally found in tin deposit The flotation separation of cassiterite from calcite remains a challenge due to their similar response to traditional reagents In cassiterite flotation, sodium oleate (NaOL) and sodium silicate (SS) have been widely used as a collector and a depressant

The flotation of rare earth (RE) minerals (ie xenotime, monazite(Nd), RE carbonate mineral) from an ore consisting mainly of silicate minerals (ie primary silicate minerals and nontronite clay) and hematite was investigated using tall oil fatty acids (Aero 704, Sylfat FA2) as collector
Copper and lead are two important and widely used metals in industry Chalcopyrite (CuFeS2) is associated with galena (PbS) in ore, and it has been a research hotspot in separating galena from chalcopyrite by flotation In this study, the flotation behaviors of chalcopyrite and galena were studied through flotation tests, adsorption measurements, solution chemistry calculation, Fourier
Fig 1(b) shows the flotation results obtained with binary mixture of minerals (at 1:1 ratio), and it can be observed that both magnesite recovery and grade reached 80% by using PCP collector at a sodium silicate dosage of 100 mg/LThus, it is clear that a selective separation of magnesite from calcite using PCP as the collector is achievable in the presence of sodium silicate
The enrichment of the lowgradephosphate ore of the TozeurNefta deposit was investigated using scrubbingattrition, ball grinding and anionic/cationic reverse flotation in order to separate phosphaterich particles from their gangue The choice of the

Selectivity among, for example, salttype minerals is a general problem, not a special characteristic RECOVERING VERY FINE PARTICLES IN MINERAL PROCESSING 281 of very fine particles A system like calcite/quartz would have a definitive se lectivity The use of oil as a collector extender here should prove useful (b) Development of column
The superficial chemical heterogeneity of sulphide minerals can be natural or induced Comminution is one possible way for changing, sometimes drastically, the surface state of sulphides, which, consequently, modifies the reactivity of the divided solid Using different investigation techniques at the molecular scale, the chemical nature of the
The secondstage process corresponds to com plete flotation and to a sharp decrease in zeta potentials INTRODUCTION As indicated by Poling (1976), the collector action of thioltype surfactants on sulphide minerals represents one of the most selective and most important practical applications of surface chemistry today
