2. Plate type electrostatic separation unit A plate or screen type electrostatic separator is also used for separation. This type of equipment mainly consists of an oval type, high voltage electrode, which induces the electric field. The material is fed through a sloping, grounded plate under gravity. The electrostatic field is effectively shorted

ElectroStatic Separation. The Electrostatic Separator separates conducting from non-conducting materials in a size range of +45 microns to 4mm. The technology enables the recovery of metals commonly difficult to separate on an Eddy Current Separator and, subsequently, lost to waste. The ElectroStatic Separator Principles of ElectroStatic Separation

Although the metal recovery from PCBs through electrostatic separation is higher, pyrolytic carbon prepared from the non-magnetic fraction shows better pore characteristics and adsorption properties. This paper might be the first report of the effect of separation technology for PCBs on the preparation of pyrolytic carbons.

Key words: mineral pigments, bolus, anatas, magnetic separation, electrostatic separation 1 INTRODUCTION The application of natural mineral pigments dates back to the Middle Ages. Since the 1970s, the demand for their production has declined as a result of the advent of organic pigments notable for their colour scheme and affordable price.

In the actual magnetic separation machine, the magnetic field strength ranges from hundreds of Gauss to 20,000 Gauss, some even exceed 20,000 Gauss, but it is rarely used in general beneficiation production. Excessive magnetic field strength will lead to weak magnetic minerals to agglomerate that is not conducive to beneficiation.

Magnetic separation exploits the different magnetic properties in ore bodies to retrieve target minerals from gangue. The process utilises the competition between gravitation, centrifugal and friction forces, magnetic forces, and inter-particle attraction or repulsion. All magnetite ore bodies will require some magnetic separation investigation.

Separation occurs by induced an electrostatic charge into a conductive dry-liberated particle. Electrostatic separators are commonly used in conjunction with high-intensity magnetic separators. The electrostatic technology is successfully used in the mineral processing, plastics and recycling industries, although there is a continual expansion ...

High Gradient Magnetic Separator • For separation of material with less magnetic susceptibility, high magnetic forces are required. An efficient way to produce high magnetic forces is the use of solenoids in the gap of a magnetic circuit. The core or working volume is fitted with a matrix of secondary poles, each producing ≤2T field strength and gradient≤14T/mm. Due to the small working ...
