It is a very rigid alloy that does not want to bend.. There is a similar piece in the picture coming up from the table leg for comparison ..( same material as i used to build the mineral jig screen box ).. The Top, Bottom and Ends are "C" channel.. Notice how the ends wrap around to the front and back . That design adds a lot of strength..

Shaking tables are one of the oldest gravity separators in the mineral processing industry, capable of handling minerals and coal of 0-2mm. Shaking tables are rectangular-shaped tables with riffled decks across which a film of water flows. The mechanical drive imparts motion along the long axis of the table, perpendicular to the flow of the water.
Processing Flow Overview. The gold dust particles are mostly granular or scale-like, and the particle size is usually 0.5 to 2 mm, but there are also gold particles weighing a few kilograms and more powdery to the naked eye. The fineness of the placer gold is usually 850-900, and the average specific gravity is …
For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage ...
Jigging for concentrating minerals is based exclusively on the differences in density of the particles. The elementary jig (Fig. 13.29) is an open tank filled with water. A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen. The feed material is poured from the top.
The present invention provides an improved design for the hindered settling bed within a mineral jig. The hindered settling bed contains relatively low density materials that can be used in conjunction with high density materials to aid in the separation of particulate materials within the mineral jig. The presence of the relatively low density barrier materials in the settling bed allow for ...
models of jig, and amultitude of theories to explain the jigging process. The limitation of jigging studies as aptly described by Kelly and Spottiswood: "Jigging is probably the most complex gravity separation, because of its conti nuously varying hydro-dynamics. The mineral bed is repeatedly moved up by the water, expands, and then resettles,

The Metanza Jigs are new generation designs for a mature, jigging technology. The leading-edge design supports a more effective recovery process and, ultimately, produces a superior concentrate while consistently delivering on lower capital and operational costs with minimum environmental impact.
For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage has led to a renewed interest in dry jigging. However, the current scenario of increasing ore complexity and the advent of smart sensor technologies, such as sensor-based sorting (SBS), has ...
This paper aims to provide insights into the factors contributing to the efficiency of separation of solids particles in pneumatic jigging. A batch pneumatic jig was constructed at the University of Nottingham, UK, for solid waste recycling. Synthetic materials (density tracers), colour coded for density, were used as the bed materials in a series of experiments. The bed was analysed layer by ...
The Kelsey Centrifugal Jig utilizes the Harz design which is divided into two parts, the top section of heavy mineral (ragging) above a screen, and the jig chamber filled with water and pulsed by a diaphragm plunger. The screen and hutch arrangement is turned 90° from the horizontal to the vertical and spun about the vertical axis.
Jigging is an ancient but mature coal washing technology by gravity. It has more than 110 years history since the application of air jigging machine. However, because the theoretical research of jigging coal washing technology is still wandering at the hypothesis stage, it also seriously relies on operator's experience and skill, which results into no publicly recognized and uniform jigging ...

Jig Concentrators are gravity concentration devices, designed and mainly used in mineral processing for washing, separation and concentration of coarse metals & minerals within the body ore, based on its specific gravity, over the selected screen mesh.. Since the high specific gravity differential of material makes good recoveries possible, use of Jig Concentrators to recover various metals ...
The Mineral Jig is built in two general types, simplex and duplex. The duplex type is built in all sizes while the simplex is standard in the 8″x 12″ size only. The simplex unit consists of one screen compartment, one hutch, and one screen box, while the duplex is just double, i. e., two screen compartments, two hutches, and two screen boxes.
This is the ratio between the material that ends up in the hutch compared to the total material run. This is only for heavy metals. When running for gems the gems end up in the screen box...near the bottom. Jim

In Metallurgy, Mineral jigs are a type of gravity concentrator, used in industry for the separation of materials with different densities.It is widely used in recovering valuable heavy minerals such as gold, platinum, tin, tungsten, as well as gemstones such as diamond and sapphire, from alluvial or placer deposits.Base metals such as iron, manganese, and barite have also been recovered using ...
Working Principle of Jig Separator The introduction of Jig separator. Jig separator, also known as jig machine, jig concentrator, mineral jig, is a compact and efficient gravity device which is widely used for beneficiaiton of a wide range of minerals. it can separate heavy liberated minerals from light minerals, works on the difference in density.
