Speed analysis of quartz and hematite particles in a spiral

Activated quartz and hematite tracers between 1180 and 1700 μm in diameter were tracked in two sections of the first two turns of a spiral concentrator to For example, Knelson concentrators, Falcon concentrators, and the SLon centrifugal concentrator have been effectively used to recover fine minerals such as gold, tungsten, native copper, and hematite Parameter Optimization of the Separation Process

Principles of spiral concentration ScienceDirect

The different stages of the mechanism of concentration in spiral concentrators are discussed. The significance of many design and operational variables The previous studies showed that the slime content of the spiral concentrator feed should be reduced to around 10% to ensure good separation (Brown, 2001). However, another work indicates aEffect of feed density at varying slimes

Size recovery curves of minerals in industrial spirals for processing

A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of the spiral Activated quartz and hematite tracers between 1180 and 1700 μm in diameter were tracked in two sections of the first two turns of a spiral concentrator to ascertain information on valuable andSpeed analysis of quartz and hematite particles in a spiral

Experimental modelling and plant simulation of spiral

Experimental modelling of a chromite separating spiral concentrator is performed. • A second data set of hematite separation results is obtained for regression. • Holland-Batt (1990) spiral model is extended to account for changing feed conditions. • Response surface and extended Holland-Batt models are evaluated for model selection. •Tracers of different sizes (53–1700 μm) and relative densities (2.7 and 4.7) have been tracked within a slurry (27% w/w solids) flowing along a spiral concentrator trough. Position with respect to time, and speed, have been used to show the general behaviour of these tracers. Speeds measured were up to 2 m/s.PEPT studies of heavy particle flow within a spiral concentrator
