The Continuous Variable Discharge (CVD) technology takes FLSmidth-Knelson's world leadership in gravity concentration beyond precious metals, which require only very small mass yields. The CVD allows mass yields up to and beyond 50%, enabling enhanced gravity concentration of base and industrial minerals, gold sulphides and other heavy mineral species.

CVD technology can ultimately only be proven and scaled up by pilot testing, for which we operate a KC-CVD6 pilot plant. Much of Knelsons CVD R&D has been conducted in our labs, and Peacocke & Simpson holds joint patents with Knelson on various CVD enhancements.

Pilot testing requires bulk samples that are often difficult and costly to obtain, so we have developed a modified concentrate cone and test procedure for our KC-MD3 semi-batch concentrator that allows us to use small samples to prove amenability before proceeding to pilot scale.
