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 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
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
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
The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because … Read more
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
