Two scientific and technological achievements of China Minmetals Rare Earth Tin Mine passed the evaluation of scientific and technological achievements of Nonferrous Metals Association

On December 30, 2020, China Nonferrous Metals Industry Association organized a scientific and technological achievement evaluation meeting in Changsha. Led by Minmetals Rare Earth Tin Mine Shanxing Antimony Industry Co., Ltd., Changsha Research Institute of Mining and Metallurgy Co., Ltd., Beijing Holist Technology Co., Ltd. and other units jointly completed the "Antimony X-ray intelligent beneficiation pre-selection and waste new technology Two scientific and technological achievements of "Research" and "Antimony Resources Waste-free Green and High-Efficiency Technology Development and Demonstration" passed the achievement evaluation successfully. Zhang Hongguo, Deputy Secretary-General and Director of the Science and Technology Department of China Nonferrous Metals Industry Association presided over the meeting.

"Study on the new technology of antimony ore X-ray intelligent beneficiation, pre-selection and waste disposal" project replaces manual manual selection with intelligent technology, frees hand-selecting female workers from heavy manual labor, and ends the backward beneficiation process. The "Antimony Resources Waste-free Green and High-Efficiency Technology Development and Demonstration" project aims at the separation of tailings and flotation wastewater, the utilization of tailings as resources, and the recycling of wastewater, achieving no waste discharge of antimony mines. The tin mine utilization research results have built a 1,000t/d antimony resource no tail green and efficient development demonstration project. After more than one year of operation practice, the production process is stable and the operation indicators are better than expected. The expert group agreed that the two scientific and technological achievements are important measures for the implementation of ecological and environmental protection, and the antimony mine has no tails and no waste water discharge; the project has broad application prospects and great promotion potential. It is a major technological advancement in the antimony industry and has a strong Market competitiveness, and the evaluation conclusions of the two projects are of international advanced level.

Zhang Hongguo fully affirmed and highly praised the work done by Xikuangshan in scientific and technological innovation. He emphasized that Xikuangshan, as the cradle and leading enterprise of antimony industry, should attach great importance to scientific and technological innovation, and continue to increase investment in science and technology around the implementation of the innovation-driven development strategy. , To promote the rapid improvement of scientific and technological innovation capabilities and help the high-quality development of the antimony industry.
