Plastics are widely used in everyday life as a useful material, and thus their consumption is growing at a rate of about 5% per year in Korea. However, the constant generation of plastic wastes and their disposal generates environmental problems along with economic loss. In particular, mixed waste plastics are difficult to recycle because of their inferior …

Electrostatic separation of ores in its present form is generally known as the Huff process, from the name of Charles H. Huff, of Boston, Mass., through whose constant and persistent labors (with the invention of Clinton E. Dolbear as a basis) the successful commercial process embracing separative machinery and the various electrifying …
During the two-step electrostatic separation experiments, 300 g raw material was used in the first step. An overview of the two-step electrostatic separation process is shown in Fig. 1.The protein-enriched fraction (GE1) and the mixture of the fractions obtained from the two collector bags (GC1 + PC1) were used as feed for the …
Electrostatic separation was performed on each of the milled ROC sample prepared with the different dissociation modes, with F0 denoting the initial material (Fig. 1). Samples were separated into two fractions: positively charged particles (F+) and negatively charged particles (F−). The particle size distribution, color and biochemical ...
Different aspects of electrostatic phase separation have been critically reviewed. Electrocoalescence of two drops involves three major stages; drop–drop …
Electrostatic separation is a dry processing technique used for the separation of primary as well as secondary raw materials by means of electrical forces acting on charged particles. Two main process routines can be distinguished depending on differences in raw material properties: separation of conductors from non-conductors
In this context, electrostatic separation is a new proposition, especially for extracting MP from mineral-rich samples and large sample volumes. However, there is little research evaluating the reliability of the technique. This study has evaluated the effectiveness of the Korona-Walzen-Scheider (KWS) system; a small-scale version of …
Electrostatic separation is one of those important unit operations where electrical conductivity property of mineral surface is used selectively to separate out desirable mineral from other undesirable minerals. Electrostatic forces are generated by the action of an electric field on a charged particle. Consequently,
Electrostatic separation (ES) offers an opportunity to separate polymeric materials of the same or very similar density [6,7]. The principle of electrostatic separation is based on differences in electrostatic forces acting on particles of the mixture exposed to the electric field [6,8].
Liquid-liquid phase separation (LLPS) of biomolecules (proteins/nucleic acids) is now well-established as a ubiquitous phenomenon for the formation of membraneless organelles 1,2,3,4,5,6.These ...
Electrostatic separation is a widely used technique in the mineral processing industry for a variety of purposes, such as beneficiation, recycling, or purification.
Current methodologies in electrostatic separation are mainly based on the electrostatic forces exerted on charged particles. Among these, corona roll-type separators are used for the sorting of metal/plastic mixtures, where the predominant force is the image force, acting on plastic particles that are charged via corona discharge.
Electrostatic separation is one of the most misunderstood physical processes used to beneficiate minerals. Nonetheless, millions of tons of titanium ores, iron ores and other minerals are processed every …

Electrostatic-separation utilizes the difference in electrical conductivity between the various minerals in a feed material to produce differential movement in the mineral grains, and although it is applied as a concentrating process to only a small number of minerals, it has proven to be highly successful with these.
Associated with comminution and particle size separation, the performance of an electrostatic separation has also been evaluated. The electrostatic separator is often used to separate copper, silver, aluminum, and other metals from insulating materials of various types in e-waste including PV panels (Tilmatine et al., 2009). This equipment ...

While the primary separating force in electrostatic separation is the electrical force (Eq. 6), particles are usually also subjected to a significant secondary force, that of drag [15]. For most practical conditions particles moving in afluid can be considered to accelerate immediately to move at a constant velocity, known as the terminal velocity.
