The invention provides an integrated separator system for the preconcentration of a material comprising one or more grizzly bars and one or more electrodes which provide a high voltage pulse (HVP) discharge to the material. The invention also provides a process for preconcentration of a material preferably a mineral within a rock which comprises: providing the material into an integrated separator system comprising one or more grizzly bars and one or more electrodes which are capable of providing at least one high voltage pulse discharge(s) to the material; applying one or more high voltage pulse discharge(s) to the material as the material is travelling along the grizzly bar(s) to preferentially disintegrate the particles containing mineral grains of high conductivity/permittivity; separating the disintegrated particles by way of the grizzly bar(s) resulting in the separation of the feed material into low grade (oversize) and high grade (undersize) products; and wherein the disintegrated particles from step b) pass through a screening element for further treatment. The present invention also relates to a process for comminution of a material.

An air filtration system having a housing. The housing has an inlet, a frame unit, a filter unit, and an outlet. A fan is positioned in the air filtration system or not, and pulls or pushes air into the inlet, and through the outlet, and has the air pass through the filter unit. The filter unit has a first and a second expanded metal metallic plate. The first plate has a first plurality of apertures, and the second plate a second plurality of apertures. Each plate has a coated layer of a dielectric conducting and antimicrobial agent polymer material. The frame unit secures the first expanded metal metallic plate at a first position in the housing, the second expanded metal metallic plate at a second position in the housing, and ensures, when the first and second expanded metal metallic plates are securely positioned in the housing, that the first expanded metal metallic plate is adjacent to the second expanded metal metallic plate and wherein a portion of the first expanded metal metallic plate contacts or is within 20 millimeters from the second expanded metal metallic plate and each aperture of the second plurality of apertures misaligns with an aperture of the first plurality of apertures.

An improved mechanical electrostatic filter assembly for filtering an air stream from particulates, comprising either a single cartridge or multiple cartridges positioned in a consecutive manner, either close together or separated from one another via air gaps, each of the multiple cartridges comprising inner filtering media, each of the multiple cartridges haying a back wall and a front wall, each of the back wall and each of the front wall having multiple openings through which the air stream is passing.

As the air stream with particulates approaching the improved mechanical electrostatic filter assembly, and hitting an outer surface of the front wall of a first cartridge, friction is established and the particulates get electrostatically charged, wherein the air stream with the electrostatically charged particulates passing through the multiple openings of the front wall and the electrostatically charged particulates are electrically coupled to the inner filtering media, the air stream exiting the first cartridge can pass through at least one additional cartridge for filtering the particulates remained in the air stream.
