  • Patent number: 11052405
    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.
