## A Review of Spiral Technology for Fine Gravity

The benefits of using the FM1 spiral for the treatment of fine grained silica sand, tin tailings, iron ore and copper were also investigated (Richards et al 2000) Other potential applications for the use of fine spiral technology include operations that currently grind their feed material to 80% passing 75µm to achieve satisfactory liberationApplications Rutile, ilmenite and zircon concentration Iron ore, chromite and manganese beneﬁ ciation Tin, tantalum and tungsten ore concentration Gold, native copper and base metal recovery Silica sands processing Pumice sand separation Titanomagnetite concentration Garnet, kyanite, sillimanite and andalusite recoveryFine Gravity Separation ausimm1 Introduction 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 bothSize recovery curves of minerals in industrial spirals for

## A preliminary study of particle separation in spiral

Spirals are used for gravity concentration of minerals and of late these have been extensively and effectively used for iron ore processing Their widespread use is mainly due to lower capital cost and higher efficiency to treat feed material in the size range of 3 mm to 45 µmAlthough operating a spiral is quite simple its design is quite challenging for specificOutotec spiral concentrators are used in most applications, particularly for concentrating lowgrade ores Manufactured from lightweight, corrosion and abrasionresistant materials, our spirals require minimal maintenance and upkeep Gives you an effective and lowcost solution for gravity separation Reduces maintenance with a durable designSpiral Concentrator minevik OutotecWe design, manufacture and supply the MD range of gravity separation equipment including spirals, shaking tables and slurry distribution and laundering systems Our Australian based head office houses the world's largest spiral manufacturing facility and produces over 20,000 starts annually In 2010/11, we manufactured HC33 and WW6 spirals forGravity Separation Mineral Technologies
