摘要：The solids concentration obtained from the aqueous suspension derived from coal beneficiation plant streams can be promptly procesd in stabilized load bearing mass by passing the solids plus proportionally added portland cement powder thru a temperature controlled pug mill. The product is then delivered to a fill area for disposal. This eliminates the need for ponds and permits the immediate reu of water in the plant. Major economies in land purchas, waste treatment, water requirements, and operating costs are effected.
