The 13th National Hydrometallurgy Engineering and Technology Exchange Conference will be grandly held in Shenzhen, Guangdong Province from April 25th to 27th, 2025. This conference is hosted by the Mining and Metallurgy Technology Group Co., Ltd., Central South University, China General Research Institute of Nonferrous Metals Co., Ltd., and Shenzhen Zhongjin Lingnan Nonferrous Metals Co., Ltd., and co-hosted by the Institute of Process Engineering of the Chinese Academy of Sciences, Wuhan University of Science and Technology, and Shenzhen Technology University. Moreover, it is jointly undertaken by 13 units including Shenzhen Ranke Environmental Technology Co., Ltd., the Metallurgical Engineering Research and Design Institute of the Mining and Metallurgy Technology Group Co., Ltd., and the National Engineering Research Center for Rare Earths, which can be called a "luxurious all-star team" in the industry! It is expected that the scale of this conference will be more than 400 people, and it will become an influential communication feast in the field of hydrometallurgy.  

Henan Jiuye Chemical Equipment Co., Ltd. was invited to attend the conference.

Over the years, Jiuye Chemical has achieved remarkable results in the research and development of evaporator technology. Take the seven-effect two-stage split falling film evaporator developed by the company as an example. This technology is at the leading level in the industry, has been widely applied in the domestic alumina industry, and successfully entered the international market in 2018. These new patented evaporator technologies, when applied to hydrometallurgical production, have greatly improved the energy utilization efficiency and significantly reduced energy consumption. By optimizing the design of the evaporator system, efficient heat recovery and recycling have been achieved, reducing the dependence on external energy sources. In a certain hydrometallurgy project, after adopting the new evaporator technology of Jiuye Chemical, the energy consumption was reduced by 30%, and the evaporation efficiency was increased by 25%, providing a successful example for the green development of the industry. 

The brilliant appearance of Jiuye Chemical at this exchange conference not only showcases the company's technical strength and innovative achievements, but also provides valuable reference experience for enterprises within the industry. With practical actions, Jiuye Chemical has injected strong impetus into the green, low-carbon, and sustainable development of the hydrometallurgy industry. 

Henan Jiuye Chemical Equipment Co., Ltd., established in 1999, is a comprehensive high-tech enterprise integrating scientific research, design, manufacturing, installation and service. It is also a specialized, sophisticated, distinctive and innovative "little giant" enterprise in Henan Province.
