Beneficiation of mineral sands: a practical outlook
Mineral sands are mined by surface mining methods including open cut mining, suction dredging, and hydraulic mining. The first stage of the mining process is to remove all timber and topsoil from the mine site. The topsoil is stockpiled for later rehabilitation of the site after mining has been completed. 5.3.1.1.
Getting the Most from Spiral Separators
Spiral separators are used to recover the fine coal fraction (2-mm to minus 325 mesh). They are expected to recover fine coal over a wide particle size range without the use of chemicals or reagents. Supported by Downer in Australia, Mineral Technologies designs and engineers cost-effective separation technologies for fine mineral applications.

Spirals AKA-SPIN: for gravity separation of minerals
Spirals AKA-SPIN are sorting devices which separate materials according to their density differences. They can be used for a grain size range from 60μm up to 2mm, with a throughput per spiral ranging between 1– 4t/h. If a higher throughput is required, 2 or 3 spirals can be combined to form one column. Principle of Operation.
