Abstract: A system for processing a sand product includes a process tank having a first compartment, a second compartment in fluid communication with the first compartment, and a third compartment that is isolated from the first compartment and the second compartment. The system also includes a first hydrocyclone configured to receive a sand mixture comprising the sand product and water from the first compartment, and separate the sand mixture into wet sand and a clay mixture. The second compartment is configured to receive the wet sand and clay mixture from the first hydrocyclone. The system also includes a second hydrocyclone configured to receive the wet sand and the clay mixture from the second compartment, and further separate the wet sand from the clay mixture to produce a clay product that can include a fully hydrated clay material. The third compartment is configured to receive the clay product from the second hydrocyclone.

Abstract: One or more techniques and/or systems are disclosed for producing beneficial re-use sand from foundry sand. Foundry sand can be collected from a mold making operation, and/or from the casting removal and cleaning process. The collected sand product can be cleaned and separated into a clay and carbon mixture, and a beneficial re-use sand. The collected sand product can be cleaned by mixing with water, and subjecting the resulting mix to a hydrocyclone at appropriate flow rates. The hydrocyclone can separate the mix into a carbon, clay and water mix for re-use, and a wet sand mix. Water can be separated from the wet sand and reused, and the resulting sand can be used as beneficial re-use sand.
