基于专利分析的钨矿物浮选技术态势研究

Research Status of Tungsten Flotation Based on Patent Analysis

专利分析是通过对专利说明书、专利公报中大量零碎的专利信息进行分析、加工、组合,获得该领域专利信息的统计规律,使这些信息化为具有总揽全局并对整个行业具有前瞻性情报的方法。浮选是目前钨矿物分选的主要方法。本文通过基于专利分析的手段,跟踪钨浮选技术动态,对钨浮选技术专利发展态势进行了综合分析。研究表明,近年来有关钨浮选技术的热点主要集中在工艺改进方面,占总数的86%;对钨浮选技术的原始创新主要集中在浮选药剂的开发方面,其中捕收剂尤为受关注,占了总专利数的5%。

Patent analysis means to obtain the statistic regulation in a specialized field by processing the fragmented patent data in patent specification and gazette. This paper investigates the research status of tungsten flotation based on patent analysis. The research results show that technology improvement is the focus for tungsten flotation technology, which account for 86%. The development of flotation agents has been the original innovation for tungsten flotation.
