Spirals in Australia mineral processing

In this process, a slurry of crushed ore is placed in a vessel such as a shaker table, spiral concentrator, or jig designed to facilitate mineral separation based on density. The specific gravity of a mineral is the ratio of its density to that of water. For example, gold has a specific gravity of 19.3, which is 19.3 times denser than water. ...

How do spiral concentrators work?

Spiral concentrators are gravity-based and used to separate low-density granular and sandy (from 18 mesh to 200 mesh—1 mm to 0.0757 μm) materials from higher-density materials. Spiral concentrators are used in many mineral processing applications. For instance, they're used to process heavy mineral sand deposits, more specifically …
