PDF electrostatic separation magnetic separation gravity separation and screening. Essentially rutile and zircon are separated by their difference in conductivity while residual gangue 2is removed by magnetic and gravity separation circuits . At this point the zircon and rutile can be dispatched and sold in their raw form as mineral sands.

The densest ore particles are separated and transferred through the sinks outlets while the less dense material is transferred to the second stage of separation where more sinks material can be recovered. The lowest density material reports to the floats discharge at the bottom end of the Condor DMS unit.

For example when separating the iron salt and sand mixture we were able to use a magnet to remove the majority of the iron from the mixture. This form of physical separation works because even though the components are mixed together they retain their own characteristics so iron remained magnetic even though it was a part of the mixture.

Oct 01 2017 Overall the conclusions from this comparison are that mineral sands score well apart from the radioactivity of the ore minerals. Most mineral sand operations ship concentrates from their mine to separate processing factories but their monazite and xenotime concentrates are likely to be too radioactive for transportation or even for storage.

Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification de sliming and de watering applications. The main purpose is to separate a stream of particles into different size fractions. However there are also applications where a fine slime fraction requires removal or where the solids need to be dewatered as much as possible.
