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.
