Research and Analysis of Phosphate Ore Flotation Reagents Based on Patent Perspective
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.
