Currently, Guangdong Gold Company's two scientific and technological achievements, "Research and Application of Key Technologies for Waste-Free Treatment of Complex Gold and Polymetallic Ore Resources" and "Research and Application of Xylan Xanthate Method for Treating Heavy Metal Ion Wastewater from Gold Smelting Plants," have won the Special Award and First Prize of the China Gold Association Science and Technology Award respectively. This breaks the historical record of the Chinese gold industry having no special award, marking the company's gold smelting technology and comprehensive utilization technology as leading in the domestic and international industries.
As the first professional gold smelting enterprise in China, Guangdong Gold Company leads in independent knowledge innovation and is the first enterprise in China to create and apply the two-stage roasting method for industrial processing of complex gold and polymetallic ores. In recent years, with the increasingly wide range of gold and polymetallic ore raw materials, the original processing system has been difficult to adapt to the company's production needs.
In order to further improve resource utilization and reuse rates and reduce waste discharge, Guangdong Gold Company, based on the utilization of the existing processing system, has successfully integrated many high-tech technologies such as gold and silver cyanide extraction and gold and silver electrolytic refining, forming a unique integrated technology. Through long-term practice, this technology has not only successfully solved the problems that single traditional technologies could not achieve, but also realized the comprehensive recovery of valuable metals, "zero discharge" of wastewater and its recycling.
During the achievement appraisal process, experts, after reviewing the materials and conducting on-site inspections, believed that the two technologies have complete data and reliable data, can process various complex gold and polymetallic ores, reflect the advantages of key technology integration, realize efficient and comprehensive resource utilization and clean production, and have wide demonstration and promotion application value. The overall technology has reached the internationally leading level and internationally advanced level respectively.
