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