1. Introduction. China has abundant reserves of coal-series kaolin resources, approaching 3.8 billion tons (Lin et al., 2018).However, with the exploitation of coal, a large amount of coal-series kaolin is discarded as solid waste to the tailings dam (Zhang and Ling, 2020).This not only occupies a lot of land resources, but also causes …

Electrostatic separation enables the separation of a wide range of minerals and this example, separating Pyrite from Silica Sand, provides a good example of the separation process. A feed of conducting (Pyrite FeS 2 ) and non-conducting (Silica Sand SiO 2 ) powders is fed via a vibratory feeder onto an earthed, stainless-steel roll …
The most commonly used techniques for the separation of particulate solids from gases are inertial separators, Electrostatic Separators and Filters. The physical phenomena involved in the separation of solids from gases are influenced by a number of important factors such as the properties of the gas, and gas-particle and particle-particle ...
Eddy Current Separators and ElectroStatic Separators play an important role in maximising metal recovery and revenue from complex streams presently processed by metal recyclers. Such technology enables the recovery and purity enhancement of valuable non-ferrous metals, with both technologies having certain key operational and …
It was suggested in the proposal that small particles, due to low inertia, may not impact on the surfaces of the tribocharger. They would, thus, not receive charge and would not be beneficiated in the electrostatic separation. A milling process was proposed in which the small particles are stirred together with larger carrier beads producing the …
The triboelectrostatic separation (TES) process had been tested successfully on bench-scale. The results obtained at FETC showed that it was capable of cleaning the coal of …
