A leader in gravity separation equipment, we design and manufacture MD spirals - the world-leading spiral for fine mineral separation.
Spirals, the most common equipment for the separation of heavy minerals such as chromite, are greatly affected by size distribution and the liberation degree (hence the specific gravity and size) of the feed particles. In this study, the efficiency of spirals in separation of low-grade chromite particles has been investigated by studying the distribution of grade, size distribution and ...
Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
Supported by Downer in Australia, Mineral Technologies designs and engineers cost-effective separation technologies for fine mineral applications. The company specializes in gravity, electromagnetic and electrostatic separation, and it's quite well-known for its spiral separators, including the LD7, the LD7RC and the LC3.

The spiral chute mainly uses the inertial centrifugal force generated by the minerals of different densities in the spiral rotation to achieve the separation of light and heavy minerals. Because of its simple equipment structure, low power consumption, and large processing capacity, it is widely used in the gravity separation process.

Mineral Technologies has pioneered high capacity fi ne mineral gravity separation equipment in the mineral processing industry for more than 70 years, with a range of high effi ciency spiral …
During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...
1.1 Spirals Spirals are one of the types of equipment which have been designed and built to effect separation of minerals by gravity. Spiral concentrators are simple low energy consuming devices that separate minerals on the basis of density. Abela (2003) said the controllable factors that affect the separation
