Jigging Separation Process Principle

The Mineral Jig is not just another gravity Separation Process. It is a highly efficient selective pulsator and concentrating machine which has the ability to treat an unclassified feed separating solids having only a slight differential in settling rates, with only a minimum addition of water. 1000s of these Mineral Jigging machines are now in operation on … Read more

Harz Jig Concentrators

Harz Type Jig The (Improved Harz Type) Jig is essentially a coarse – mineral Jig Concentrator embodying improvements on the Harz Jig and the Ellis Jig. It will handle successfully all types of ores which can be treated by gravity concentration with feed size ranging from ¼” to 1½”. These jigs are made in three sizes … Read more

Small & Laboratory Jigs

Laboratory Jig (Harz Type) There are many ores, such as zinc, lead, iron, and fluorspar which can be treated economically in jigs handling very coarse feeds; either to make a high grade concentrate or to discard a coarse, clean tailing. The small (Harz Type) Laboratory Jig accurately tests the possibilities of such an ore. The … Read more

Easy Mill Expension: Grind Less, Float Coarse, at Higher Tonnage

The Problem with Coarse Flotation and Recovery Many flotation plants today are grinding to fine sizes. This means that money is being spent grinding worthless gangue which might be discarded at a coarser mesh. Many plants are treating ores in which the gangue is free at a coarse mesh and where a coarse bulk concentrate … Read more

Mineral Jigs for Concentration of Lead Ores

The following notes are taken from results obtained on a standard 25-ft. Hancock jig tested during regular operation. The object of the tests was to determine the conditions for most effective work, and the nature of products that could be made. The material treated was sized between 9-mm. and 2-mm. round- hole screens, and was … Read more

Mineral Jig in ball mill-classifier circuit for removing sulphides for fine grinding and subsequent cyanidation leach. ORE TREATED: Sulphide gold or silver ores where fine grinding of the sulphides is necessary to expose the gold or silver to the cyanide solution and where it is … Read more

Gold Jig DIY Plans Hand Operated

Gold Jig

For for Coarse Gold Recovery (>2mm), here is an easy to build hand-operated mineral jig.  This jig can be used for batch ‘jigging out’ gold from oversize (>10 mesh) from pre-sluicing or panning rejects as occasionally there will be coarse nuggets present in the oversize rock and this can-be-homemade jig works as a simple hand operated … Read more
