A Genuine Canadian Success Story
In the late 1990's, the Knelson Continuous Variable Discharge, or CVD Concentrator was commercialized. This concentrator is designed to produce a continuous stream of concentrate and targets higher mass yield applications such as gold sulphide and heavy mineral recovery where higher mass to concentrate is required. Today, Knelson still
