摘要
1引言淀粉是一种非离子型的有机高分子聚合物，其基本结构单元是。一葡萄糖，分子式为（Cp；ps）N，它能选择性地抑制某些硅酸盐和氧化矿物"'。淀粉对矿物的抑制机理主要是由于它具有附着于矿物表面而体表面丰水的能力。汽粉加何与矿物发生键合，说法较多。BalaieeSR等人?..
In dodecylamine flotation system, depression of starch and Pb2+ plus starch on nine silicate minerals belonging to five silicate structures is tested. Through testing X-ray photoelectron spectroscopy and potential of silicate minerals, based on crystal chemistry characteristics of silicate minerals, depression and synergetic depression mechanisms of starch and Pb2+ plus starch on silicate minerals with different crystal structure are analyzed. It is considered that these depressions are dosly related to properties, valences, quantities, solubility and ability to combine hydroxy of surface ions of silicate minerals with different crystal structure liberated.
