industrial one or an ore, e.g. rutile is an ore for the titanium mineral and an industrial one when for its high refractive index and colour, used as a white pigment. Diversified industries need minerals as raw materials with a wide price range, e.g. the high market rate of industrial diamond is in per gm or kg whereas 17 CHAPTER

In the early days of ore beneficiation, hand sorting was used to separate spodumene (Munson and Clarke, 1955) and gold ores (Barton and Peverett, 1980). However, the need to process a large tonnage of low grade ore, and the need for fine milling to improve mineral liberation led to the decline in the application of hand sorting in …

Talc is a magnesium silicate clay mineral and when present in molybdenite concentrate, contributes to the acid-insoluble content. Talc has a laminar structure as shown in Fig. 4.As can be seen, talc is a tri-layered hydrated magnesium silicate with a chemical formula of 3MgO·4SiO 2 ·H 2 O or Mg 3 (Si 2 O 5) 2 (OH) 2 (Xu et al., 2018, …

Talc also causes the concentrate froth to be rigid and takes longer to break down. It also consumes a large amount of reagents in flotation. In the processing of high talc-containing copper-cobalt ore, talc is dealt with by pre-floating it together with quartz and other phyllosilicate minerals (muscovite, micas, chlorite, and serpentine) ; .

The specific gravity of talc is about 2.75; it is relatively inert, and water repellent (Engel and Wright, 1960). Talc is formed by the alteration of serpentine. The resulting talc …

The talc chlorite was improved to 82% by attrition in the presence of sodium hexametaphosphate at a pulp density of 76% [3]. Beneficiation of talc-carbonate ore using polypropylene glycol as a frother was studied to increase the rate of talc flotation [4]. A clean concentrate analyzing 93.5 % talc was obtained at a recovery

Talc remains an important mineral with a wide array of applications in paints, paper, polymers, pharmaceuticals, and cosmetics industries when its associated impurities were accordingly processed due to its distinct surface properties. Thus, treatment of a Nigerian talc ore consisting of talc, vermiculite, and phillipsite was investigated using …

The flotation process of talc is relatively simple, requiring only one rough selection and sweep selection, and 3-4 selections. However, talc concentrate has a fine particle size and is difficult to dehydrate. flotation machine. 2. Hand sorting. Hand sorting is selected by manual hand according to the difference in smoothness of talc and gangue ...

The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr2O3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.

Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, …

Ca (g/min cm2), the maximum solids concentrate rate or carrying capacity in column flotation, is expressed as the mass of solids from the overflow per unit of column cross sectional area. It can be measured for a given set of operating conditions by determining concentrate solids rate as a function of feed solids rate. Carrying capacity is …

The New Concentrator of Kipushi (NCK) is a typical example of a plant processing high talc-containing copper-cobalt ore, the simplified flowsheet is given in Figure 1. At NCK, the beneficiation of copper and cobalt ore involves a combination of concentration by froth flotation and classical gravity separation by spirals and shaking tables.

It can separate talc from gangue according to the different frictional coefficients of ore, thus realizing the mechanization of talc manual selection. (3) Electrostatic beneficiation. In addition to talc, talc ore also contains magnesite, magnetite, magnetite, tremolite and other minerals, with an embedded particle size of 0.

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making.
