在位于云南省昆明市晋宁区的云南云天化股份有限公司研究院实验室里，41岁的高级工程师刘润哲和团 队其他同事一起，反复做着有关磷矿资源利用方面的各种实验。清晨八点多投入工作，直到夜色深沉才 结束，这样的工作节奏，他们保持了十余年。 刘润哲说："团队17名成员都是专职研发人员，我们建立了磷矿从小试到中试、逐级放大的各级研究平 台，系统开展提高磷资源选矿回收率的研发工作。11年来，这项工作一直持续开展，从未间断。" 经过多年努力，团队取得了丰硕的研究成果。团队成功自主研发尾矿再选新技术、浮选YP系列新药剂 等集成技术，形成了具有自主知识产权的浮选磷尾矿源头减量技术。近年来，云南云天化股份有限公司 持续加大研发投入，对选矿装置进行技术升级，实现浮选磷尾矿源头减量技术产业化应用。这项技术的 产业化应用，降低了选厂的操作难度和工作强度，使磷矿选矿回收率从88%提高至95%，创云南胶磷矿 选矿尾矿品位历史最优纪录，在国际上达到领先水平。 云南云天化股份有限公司研究院副总经理王孟来说，这项技术使磷矿选矿回收率提高了7个百分点，解 决了制约中低品位胶磷矿开发利用的技术"瓶颈"，有效提高云南磷矿资源综合利用率。 目前，相关技术成果 ...

Core Viewpoint - The team at Yunnan Yuntianhua Co., Ltd. has successfully tackled the challenge of efficiently utilizing low-grade phosphate resources, significantly improving the recovery rate of phosphate from low-grade phosphate ore [2][3]. Group 1: Phosphate Resource Utilization - Yunnan Province has abundant phosphate resources, primarily low-grade phosphate ore, which has historically posed challenges in mining and utilization due to high impurity content and low recovery rates [2]. - The company established a dedicated research team focused on the flotation technology for low-grade phosphate ore, which has been working for over 11 years to enhance phosphate recovery rates [2][3]. - The research team developed new technologies for re-selecting tailings and flotation agents, achieving a phosphate recovery rate increase from 88% to 95%, setting a historical record for Yunnan's phosphate ore [2][3]. Group 2: Technological Advancements and Impact - The new technology has effectively addressed the technical bottlenecks in the development of low-grade phosphate ore, leading to improved comprehensive utilization of phosphate resources in Yunnan [3]. - The application of these technological advancements has been implemented across multiple phosphate mining plants, resulting in increased company revenue and significantly reduced tailings discharge, achieving social, corporate, environmental, and economic benefits [3]. - The research institute has established multiple research teams focusing on core technological innovations in phosphate and associated resource utilization, with over 1,050 patents and more than 200 research projects completed during the 14th Five-Year Plan period, including 12 projects reaching international advanced levels [5].
