A process for the recovery of drilling fluid additives, including industrial carbon, calcium carbonate, natural and synthetic fibers, and other materials from a mixture. The mixture may include drilling fluids, drilled solids, and drilling fluid additives from a mud system. The process may include: separating at least a portion of the drilled solids from the mixture to form a first effluent and a drilled solids fraction; separating at least a portion of the drilling fluid additives from the first effluent to form a second effluent and a recovered additives fraction; and recycling at least a portion of the recovered additives fraction to the mud system. The drilling fluid additives may have a specific gravity greater than 1.4, and may include particles having an average size greater than 2 microns. |
