Spiral concentrators are used in the iron ore industry to separate heavy iron oxide carrier particles from the light silica ones. Losses of iron occur mainly in the fine (− 75 μm) and coarse (+ 600 μm) size fractions. This paper analyzes the radial distribution of iron oxide and silica particles in the reject of a 7 turn spiral.Web

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)Web

The aim of this paper is to provide information about particle trajectories and speeds recorded following PEPT tracking of tracers in the first two turns of a spiral concentrator processing an iron ore slurry. This information is necessary for validation of future particle–fluid flow simulations (e.g. numerical simulation) of a spiral ...Web

The mined ore was to be stockpiled and blended to achieve this operating range. The material was to be screened and scrubbed to liberate the HM from the clays. The feed was then pumped to the Feed Preparation area of the Concentrator. The concentrator utilised gravity separation and wet magnetic separation to produce a Heavy Mineral Concentrate.Web
