Size recovery curves of minerals in industrial spirals for processing

Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992).The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).The spirals operate on both particle size and …

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. ...

Coal separation technologies

Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such as pyrite (4.9 to 5.2). Different technologies such as jigs, heavy (dense) media separators, spiral concentrators, and teetered beds, use these differences in density to separate coal from rock.

Evaluation of ultrafine spiral concentrators for coal cleaning

environment concerns. 4+3 short turns two-staged spiral concentrator has been developed, applied in ultrafine coal cleaning circuit, and operated at a lower flowrate than that of spiral used in fine coal cleaning circuit. Ultrafine spiral concentrator is a specific gravity-based separator.

Gold Spiral Wheel Concentrators

But with a good spiral wheel concentrator properly set up you can process 50 to 150 lbs. of black sand concentrates an hour with very little effort and have clean gold ready to display or sell. So, if you mine for gold and do not want to sit around for backbreaking hours panning and then picking out the black sand by hand you need to consider ...

Spiral Separators VS Concentrating Tables

The typical spiral unit consists of a spiral conduit with a modified semi-circular cross section. As the slurry flows down the spiral, those minerals with highest specific gravity move to the inner edge of the spiral while the light material moves upward to the outer edge of the spiral. A full size spiral concentrator is shown in Figure 2.

Spiral Concentrator

A spiral concentrator is a device that relies on gravity to separate material in a slurry feed. The light density granules are separated from the heavier density material.

Evaluate Spiral Concentrator Circuit Performance

The results of the linear circuit analyses should not be taken to imply that traditional multi-stage spiral circuits have no value. The primary advantage of these traditional circuits is that they provide an effective means for reducing the specific gravity cut-point (SG50) below that which may be achieved using a single-stage spiral.
