An important feature of the test circuit is the ability to recycle a fraction of the tails, for further treatment. The volumetric recycle ratio S is defined as the ratio Q RT /Q NF where Q RT, Q NF are the volumetric flow rates of recycled tails and new feed respectively, m 3 /h. Thus the number of times N that a particle passes through the Cell is, on …

The BGRIMM …
Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13, 14]. So, flotation of fine particles is one of the major challenging tasks.

Pneumatic Flotation Machine (mining flotation machine) is suitable for large and medium-sized mineral beneficiation plants for roughing and cleaning flotation operations. It is applied for non-ferrous metals, ferrous metals and non-metallic minerals,the feeding particle size range of 0.3 ~ 0.01mm(-0.074mm particle size >50%).
After the pulp and flotation reagent are fully mixed, they are sent to the flotation column through the central feeding device. The pulp is slowly descended under the action of gravity, and the compressed air is dispersed into a large number of tiny bubbles through the inflator, which are evenly distributed on the entire section of the …

Introduction of air flotation machine. The dissolved air flotation (DAF) is mainly used for solid-liquid or liquid-liquid separation. Through the air-dissolving and release system, a large number of fine air bubbles are generated in the water, making them adhere to the solid or liquid particles in the wastewater,so that density is close to that of water, resulting in a …
Effect of process variables As mechanical flotation is closely related to the amount of floated water, the recovery of gangt~e depends on factors that control froth characteristics and water recovery.

The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 0.25% – 2.0% SiO2. Reverse flotation (silica is floated away from the iron concentrate) has proven to be an economical and effective method for reducing the concentrate silica content to very low levels.
