Recovery of OxPure 612C-50 Coconut Carbon Particles Using Bump Arrays Available to Purchase

Displacement arrays are useful for separating particles from carrier fluids such as blood cells and inorganics such as sand. The arrays of offset posts allow smaller particles to flow in the streamlines and cause larger particles to move around the posts migrating to one side. Migrating increases the particle concentration in one direction and depletes the particle concentration in the other direction. This allows particle separation to occur.

Experiments to separate large OxPure¹ 612C-50 coconut carbon particles in Newtonian slurries were conducted using bump arrays. The mesofluidic system uses an array of staggered posts as configured in a bump array for Newtonian slurry conditions. The results of these separation experiments are described. This information could be applied in gold recovery settings that use counter current cyanide processing.
