Henan Yuguang Zinc Industry Co., Ltd. 300,000 tons of zinc project is Yuguang Group in order to give full play to the advantages of complementary zinc and zinc, adjust the product structure, maximize the comprehensive utilization of resources to improve corporate profitability and market competitiveness and launched s project.
  300,000 tons of zinc a 100,000 tons of zinc project was included in Henan Province and Jiyuan City key projects. The total investment of 860 million yuan, in August 2003 to start construction, May 18, 2005 output of the first batch of zinc ingots. 300,000 tons of electricity zinc two 100,000 tons of zinc project a total investment of 880 million yuan, the project currently represents the world's mainstream zinc smelting zinc smelting process, SO2 recovery of acid, smelting recovery rate of 95% The impact of small, while the comprehensive recovery of lead, silver, copper, cadmium, cobalt, indium, iron and other 10 kinds of valuable metals. August 8, 2008 completed, September 25 officially put into production, the project from start to completion only lasted 1 year and 3 months. Electric zinc two built the first fully enclosed forced ventilation wet zinc electrolysis system, fundamentally solve the zinc smelting industry, zinc workshop environmental problems. The second phase of the main equipment roasting furnace from the installation to the masonry cap, only 133 days, creating the fastest construction of the country record. June 2008, Yu Guang licensing high-purity zinc in the London Metal Exchange (LME) registered successfully, becoming the first seven, Henan Province, the first registered in the LME high-purity zinc products manufacturing enterprises.
  At present, the zinc industry has formed 250,000 tons of zinc ingots, sulfuric acid 400,000 tons of annual production capacity, the scale of production ranks the top three domestic zinc smelting industry.
  In recent years, Zinc industry companies do a good job of spontaneous innovation and scientific research and development of innovation, focus on recycling economy comprehensive recycling, low-carbon energy conservation and environmental management and so on. Recycling economy, by summing up the wet selenium acid leaching pulp properties and process characteristics, increase the flotation ore high trough, dense pool using nano-zinc oxide to adjust the acidity and so reduce the wet zinc smelting high acidity, high temperature and many other effects, Silver yield increased by 10% or more, the year can be more recycling silver metal 1500kg, direct economic benefits of 4 million yuan.

  Through the implementation of increased copper slag pickling tank volume and adjust the acidity, reducing the loss of cadmium in the copper slag, while in the purification part of the strict control process to avoid cadmium into the dispersion of cobalt residue loss. In the cadmium fire production in the selection of the industry's advanced stainless steel tower distillation. Cadmium directly increased to 80%, the annual recovery of metal can be 80t, the output value of 1.6 million yuan. In the aspect of environmental management, the cooling tower is improved, and the cooling capacity of the cooling tower is improved by 99.5%. At the same time, a certain amount of zinc, acid , Greatly improving the surrounding environment. Energy-saving emission reduction, in order to achieve the "Eleventh Five-Year" at the end of the unit GDP 20% energy saving target, zinc industry set up a leading group of energy saving, take a variety of measures pay close attention to energy saving work, energy saving effect.
