Pioneering mineral processing technologies and systems
Early results indicate NovaCell™ could unlock a 40% reduction in comminution energy and a 12% reduction in overall site operating cost. Jord's patented NovaCell™ flotation technology recovers a wide particle size range, from the lower limit of flotation to the upper limit of coarse particle flotation. This ensures maximum product yield.

Conversely, in mineral flotation or dispersed air flotation systems, about 10 m 3 of air are dispersed into 1 m 3 of water (pulp) or 500 times more than that used in DAF. Thus, DAF microbubbles are used to capture only the small, light solids and metal-ion hydroxide flocs, bacteria, etc., having specific weights close to that of water.
