Fluoride fixation and cyanide removal are carried out through innovative processes，and the process water is recycled and not discharged. The environmentally friendly solid materials are made into no-burn bricks after batching, molding and maintenance. There is no "three wastes" and other hazardous substances in the production process, which is environmentally friendly and economical.
