Research Progress on the Application of Inorganic Polymer Flocculants in the Field of Mineral Processing
Inorganic polymer coagulants are widely used in the flotation of fine-grained minerals,tailings concentration and mineral processing wastewater treatment and other mineral processing processes.This paper comprehensively analysed the chemical properties and flocculation mechanism of inorganic polymer coagulants,and discussed in detail their practical applications in the field of mineral processing.Inorganic polymer coagulants could not only change the surface properties of the target mineral particles,appropriately increase the size of the particles and thus improve the flotation separation efficiency of micro-fine-grained minerals and pulsates,but also enhance the concentration performance of the concentrate and tailings,and effectively reduce the pH value,chroma,COD,BOD,SS,heavy metal ions,and other pollutants in the beneficiation of wastewater content.The synthesis and application of new composite inorganic polymer coagulant is the focus of future research on this type of coagulant,and the application of the mixing and matching of inorganic and organic as well as microbial polymer coagulants is also a hotspot in research and practice.This paper provides useful references for the separation,treatment of concentrate and tailings in mineral processing and the purification technology of beneficiation wastewater.
