KRTC has a full pilot facility for testing bulk mineral samples through the Knelson Continuous Variable Discharge Concentrator (CVD).
The continuous concentrator is applicable to high mass yield applications that typically range between 1 and 30%. The mass yield is completely controllable from zero to 100%. The pilot facility can currently handle testing feed percentage solids between 10 and 40%.
The pilot facility consists of 2 large agitated sample tanks, pumps, piping, and a pilot CVD6. A full range of support equipment including size analysis, sample-drying equipment etc, supports the pilot plant.
CVD testing is custom work and requires consultation with KRTC's staff.
CVD testing is performed at a pilot scale and requires at least 500 kg of sample. Particle size should not exceed 2mm. It is the responsibility of the client to provide a sample that is representative of the stream to be tested.
"Being able to learn first-hand about the Knelson concentrators from one of the most experienced people that Knelson Concentrators works with all over the world, tells me that indeed there is no better gravity solution for any gold project than the Knelson concentrator."
