A fluidized inertia table for separating materials between an upstream delivery station and a downstream receiving station is provided. The fluidized inertia table for separating materials creates a moment of inertia and/or rotary motion which are then translated into reciprocating or jarring motions and separates the materials loaded onto the tray.

The present invention relates to an air jigging machine for the dry processing of raw materials, particularly coal, comprising at least one material feeding device (1), at least one jigging material carrier (2), which is provided with openings, an air funnel (3), which is arranged below the jigging material carrier (2) and by means of which an air flow can be fed as working air (4) to the jigging material carrier, which working air is composed of a partial flow constantly flowing through the jigging material carrier (2) and a pulsing partial flow superposed thereon, such that the working air (4) can flow through the material fed onto the jigging material carrier (2) and said material can be stratified into a heavy material layer (5) acting as a jig bed and into a light material layer (6) lying thereon, and a discharge device (7) for the heavy material and light material stratified on the jigging material carrier (2) during the jigging process.

The invention relates to a method and system for the environmental remediation of materials that are contaminated with heavy minerals, such as heavy metals. The invention finds utility in removing heavy minerals from materials such as soils, sediments, mine tailings and ores. The invention provides a means for removing heavy minerals from contaminated materials without the use of water while reducing the generation of dust. Thus, the invention provides an environmentally friendly method for the remediation of sites that are contaminated with heavy minerals.

A generally elastic riffle assembly useful with a dry washer is provided with a frame that is receivable within the washer opening through which the mined particulates descend while the washer is agitated to separate the denser particulates and a set of inclined transverse riffles aligned across the frame to form wedge shaped transverse cavities in which the descending particulates are collected. Each of the riffles further include a plurality of generally vertical posts attached to their elevated edges which assist in the separation of the particulate flow and in setting off of the various modes of elastic motion of their corresponding riffle.
