摘　　要：随着我国对矿山环保力度的不断加强,绿色选矿药剂的研发显得尤为重要。淀粉以来源广、价格便宜、绿色、可再生和易降解等优势,常被用作黄铁矿、方铅矿、辉钼矿等硫化矿与角闪石、滑石、蛇纹石等硅酸盐矿物的抑制剂。本文介绍了淀粉的结构与性质,阐述了淀粉对不同硫化矿物及易浮脉石矿物的抑制作用及机理,以期学者们对淀粉展开深入研究,实现淀粉在选矿领域的广泛应用。With the continuous improvements of the mine environmental protection of China,the research and development of green beneficiation reagents are particularly important.Starch is wide Source,cheap,green,renewable,and easy degradable.It is often used as a depressant for sulfide minerals such as pyrite,galena,molybdenite and silicates such as hornblende,talc,serpentine,etc.This paper mainly introduces the structures and properties of starch,and expounds the role of starch in flotation of sulfide minerals and gangue minerals.In addition,the depression mechanisms are revealed.The paper provides the references for the scholars to carry out the in-depth research on starch and realize the wide application of starch in mineral processing fields.
