Industrial Waste

DONGSHENG recycles industrial waste, mainly valuable metal waste including: electronic plating waste (gold/silver-containing wastewater sludge and anode slime), chemical plant waste catalysts (platinum/palladium/rhodium carrier catalysts), and jewelry processing waste (gold powder scraps and platinum-containing polishing dust). Electronic plating waste undergoes electrolytic refining to purify gold and silver. Waste catalysts from chemical plants are melted at high temperatures to concentrate platinum group metals. Jewelry industry waste is processed through cyanide leaching to recover precious metals. These recycled valuable metals are transformed into raw materials like standard gold bars and platinum powder, which are reused in manufacturing electronic coatings, automotive catalysts, and high-end jewelry – forming a closed-loop recycling system.
