The role of jigs in modern ore dressing

continuous range of composition from 100 per cent gangue to 100 per cent free mineral frequently complicated by the presence of other heavy and semi-heavy minerals. However, as soon as jigs were used on alluvial tin dredges, it became practicable to analyze their efficiency for mineral recovery through the screen over a wide range

Numerical methods in mineral processing: an overview

Mineral processing includes various processes and unit operations that involve particle flow, turbulent fluid flow, and their interactions. These multiphase systems and interactions are opaque and quite difficult to study and hence quite challenging to optimize. ... Jigs. Jigging is a process in which a pulsating bed of water is used to ...

Jigging

Jigs are continuous pulsating gravity concentration devices. 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.

Jigging Separation Process Principle

The hand of duplex Jigs is determined by facing the rotating water valve, and with feed entering from the left and passing to the right, the Jig is right hand. A Jig is a left hand unit when facing the rotating water valve—mechanism side; the feed passes from right to left. Note the layout drawings showing the hand of Mineral Jigs.

Mineral Jigging Review

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 …
