The overall benefit of the fluorine reverse flotation circuit in terms of fluorine removal was far better than the use of the CMC ... (Stuart and Down, 1973, Smith, 1986); regrinding (Kappes et al., 2007 and Byrne et al., 1995) and controlled-potential flotation (Senior et al., 2006, Smith and Bruckard, 2007). Chemical depression strategies ...



For single mineral flotation tests, the floated and tailing fractions were collected separately and dried afterwards before being weighed. For artificially mixed minerals flotation, the concentrates and tailings were assayed (Chinese standards GB/T 5195.1-2006) to acquire the grades of fluorite and barite, before calculating the recovery …







In addition to flotation, Li et al. investigated the washability of microcrystal mineral graphite using float–sink analysis in terms of granulometry for specific gravity ranging from 1.3 to 2.0 ± 0.1 . The main gangue mineral was quartz in approx. 10% by weight; the recovery of graphite was almost 90 wt% with fixed carbon content 72.29 wt%.

The electrodes are stationary and composed of an appropriately durable material. The belt is made of plastic material. The separator electrode length is approximately 6 meters (20 ft.) and the width 1.25 meters (4 ft.) for full size commercial units. The power consumption is about 1 kilowatt‐hour per tonne of material processed with most of ...



A new version of the automatic activation technique for the determination of fluorine, silicon and barium in fluorspar and barytes using an isotopic neutron source is presented. The main components of the automatic equipment consist of a sampling device and a "one-chamber" irradiation and measurement part with source transfer between the irradiation and the …







This collector has been used in flotation of silicates, such as andalusite, quartz, and kyanite, but also finds application in barite flotation (Zhu et al., 2015, Jin et al., 2016). For example, micro-flotation tests with 0.3 g/L SPS as collector and 1.28 × 10 −6 mol/L of hexametaphosphate (SHMP) as depressant in an alkaline environment pH ...

As shown in Fig. 2, the flotation recoveries of barite and fluorite were very high with NaOl alone, indicating the poor selectivity between fluorite and barite in the absence of GS. With the addition of 75 mg/L GS prior to NaOl, the flotation behavior of fluorite was not affected at pH 6.0-8.0 but slightly decreased to a certain extent at





In barite flotation, the addition of metal cations can expand the pH range of mineral flotation and play an activating or inhibiting role. Aluminum sulfate is an effective inhibitor of barite. When the pH of the slurry is 4.5~7.5, aluminum sulfate has a strong inhibitory effect on barite, while fluorite can still maintain good floatability.





During flotation, particles are separated based on the differences in their surface hydrophobicity. Hydrophobic particles attach to bubbles, facilitating the differentiation between floating and sinking particles [16], [18]. Therefore, flotation can be used to separate the two active materials in black mass (BM) derived from spent LIBs.



Flotation recovery increased with increasing adsorption density to about recovery at maximum oleate adsorption density at pH 9.0 to 10.0 in the region of the zero point of charge (zpc) of the Nigerian baryte and to about recovery and maximum oleate adsorption density at the temperature range 30 to 40°C, also at the zpc of the baryte.
