【摘要】 磷矿资源是国家不可再生的战略资源，中低品位胶磷矿为主的分布特征和磷资源需求第一大国的现状决定了我国磷矿亟须高效能磷矿选矿。中低品位磷矿石需要选矿富集后才能用于农业和工业生产，浮选药剂是磷矿浮选能否取得良好指标的关键。利用Patentics专利数据库，从专利文献计量学角度对磷矿浮选药剂专利进行了系统检索与统计分析，对专利申请趋势、专利价值、专利创新主体分布和合作网络、专利技术路线等研究现状展开全面分析，剖析目前存在问题并提出相应建议。更多还原

【Abstract】 Phosphate ore resources are a non renewable strategic resource of the country. The distribution characteristics of medium and low-grade colloidal phosphate ore as the main source and the current situation of being the largest country in phosphorus resource demand determine that China urgently needs high-efficiency phosphate ore beneficiation. Low to medium grade phosphate ore needs to be beneficially enriched before it can be used in agricultural and industrial production. Flotation reagents are the key to achieving good indicators in phosphate ore flotation. This article uses the patents database to conduct a systematic search and statistical analysis of phosphate ore flotation agent patents from the perspective of patent bibliometrics. It comprehensively analyzes the research status of patent application trends, patent values, distribution of patent innovation entities and cooperation networks, patent technology routes, and other related issues. It analyzes the current problems and proposes corresponding suggestions.更多还原
