中国工程院院士沈政昌：依托人工智能技术推动浮选装备转型

Core Viewpoint - The development of flotation equipment in China has transitioned from following international trends to leading innovations, with significant contributions from industry leaders like Shen Zhengchang. The focus is now on accelerating the digital and intelligent transformation of flotation equipment through advanced technologies like artificial intelligence [1][6]. Group 1: Flotation Technology Overview - Flotation is a method for separating valuable minerals from ores based on their surface properties, with historical roots in ancient gold and silver processing [2][5]. - The global flotation technology has evolved significantly, with approximately 90% of non-ferrous metals and 50% of ferrous metals processed using flotation methods today [2]. Group 2: Historical Development of Flotation Equipment - China's flotation equipment development began in the mid-20th century, initially imitating Soviet designs before moving to independent research and development in the 1970s [5][6]. - The first large flotation machine with independent intellectual property rights was successfully tested in 2001, marking a shift from following to competing on an equal footing with international standards [5][6]. Group 3: Current Achievements and Innovations - By 2010, China had developed flotation machines of 200 and 320 cubic meters, breaking the monopoly of Western countries on large flotation equipment [6]. - China is now a leader in the development of flotation machines, having created the world's largest flotation machines of 680 and 800 cubic meters, and new devices utilizing fluidization principles for resource efficiency [6][11]. Group 4: Challenges and Future Directions - The increasing demand for mineral resources and the depletion of high-grade ores necessitate continuous innovation in flotation technology to improve efficiency and sustainability [7][11]. - The transition to larger flotation machines involves complex challenges, including maintaining similar fluid dynamics within larger volumes to ensure effective mineral separation [8][11]. Group 5: International Expansion and Recognition - Chinese flotation machines have been exported to numerous countries, overcoming initial skepticism regarding their reliability and performance compared to foreign equipment [9][10]. - The success of these machines in international markets has been bolstered by the demonstration of their efficiency and cost-effectiveness [10]. Group 6: Technological Transformation and Industry Integration - The future of flotation equipment lies in digitalization, information technology, and intelligent systems, with a focus on enhancing operational efficiency and reducing resource consumption [11][12]. - The integration of technological innovation with industry practices is essential for achieving high-quality development in flotation technology [15].
