A complete range of spirals for minerals concentration
5 • Spiral Concentrators Washwater Washwater spirals require the addition of water at various points down the spiral and therefore provide a "washing" of the concentrate, i.e., transporting away light gangue from the concentrate band. The design of the H9000W spiral, and especially the wash water system, was developed to meet the needs of

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) Optimum Operating Conditions of ... ="Gravity Spiral …

Chalcopyrite
Chalcopyrite may also alter to iron-bearing minerals because it contains iron as much as copper. Its chemical formula is simple as is common among the sulfide mineral group: CuFeS 2. Pyrite is paler and greenish yellow on the left. Chalcopyrite next to it has much more intense yellow color. Reddish patch on the left is an igneous rock monzonite.
