We unswervingly implement the concepts of “Put people and life above everything else” and Lucid waters and lush mountains are invaluable assets.”,being a model on safety and environmental protection in nonferrous industry. We highly valuethe protective development and utilization of resources, vigorously promoting new technologies such as pre-selection and waste discarding, secondary resource utilization and low-grade resource utilization, tofully improve the level of resource conservation and recycling. Sticking to the basic target of “Zero Death, Zero Injury and Zero Accident”, we fully implemented the “15 Tough Measures on Safety Production” and 69 specific measures made byYunnan Province for safety production,and carried out special investigation and rectification on major potential accidents to keep the safety production stable. What’s more, land reclamation and greening and geological environment governance were carried out, which brought the survival rate of reclamation over 95%. We also actively respond to the national call of “carbon peaking and carbon neutrality”, with acceleration of the green and environment-friendly transformation of production mode, maintainence of the  smelting techniquesof tin, copper, zinc and indiumleading in the industry, and promotion of zero discharge of waste water, ultra-clean emission  of waste gas, complete utilization of waste residues and comprehensive control of noise, to promote the harmonious coexistence of production activities and the natural environment, proctecting lucid waters and lush mountains.
