1. Introduction. Triboelectric separation provides a means to beneficiate fine minerals with an entirely dry technology. Compared with the wet separation, dry separation shows advantages of much lower energy consumption, avoid changing native properties of materials and the ability to be applied in areas where water resources are scarce, .As one of the major dry …
In this study, several tests were examined to analyze the sortability of magnesium oxide (MgO) by the use of triboelectrostatic belt separation. The objective of the study is to find a dry sorting technique to separate MgO from accompanying components such as CaO and SiO2. The aim of this first series of experiments was to develop knowledge about the …
Additionally, dry beneficiation process can be economically competitive and environmentally safe. Triboelectrostatic separation is one such technique and is very effective when applied to fine coal unlike other dry beneficiation techniques. This work involves the design (mathematical and physical) and testing of a novel triboelectrostatic ...
In this study, several tests were performed to analyse the triboelectrostatic charging behaviour of an artificially mixed sulfidic copper ore consisting of quartz and chalcopyrite. To check the surface charge of the pure mineral samples, they were analysed in a self-developed triboelectrostatic charging unit. After that, the artificially mixed sulfidic copper ore was sorted …

Abstract. Triboelectrostatic beneficiation of coal combustion fly ashes with high-unburned carbon contents can produce low-carbon ash products having value as mineral admixtures and meeting technical requirements for replacing cement in concrete. This capability is a result of establishing bipolar charge on mineral ash versus carbon particles ...

Triboelectrostatic separation is a promising method used to separate non-conductive minerals. However, the knowledge about the underlying triboelectrification mechanisms is still very limited. Thus, predicting the separation results and finding proper separation parameters are challenging tasks.This article presents a comprehensive summary of phenomena and factors …
This study covers the triboelectrostatic separation of Polyvinylchloride (PVC) materials from mixed plastics such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), and polystyrene (PS). The PVC material generates hazardous hydrogen chloride gas resulting from the combustion in the incinerators. The laboratory scale triboelectrostatic separation system …
A dry triboelectrostatic process is useful to separate PVC from the mixed plastics, which is based on the difference in the surface charge of various components of the powder mixture by the parti-cle-to-particle impact and the particle-to-wall impact. Some of the mechanisms proposed for electrostatic contact charging include elec-

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 more than 90% of pyritic sulfur and 70% of the ash-forming minerals from a number of eastern U.S. coals. It was necessary however, to test the process on a proof-
