Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.
不同淀粉药剂在矿物表面表现不同作用,原淀粉主要是氢键的作用,阳离子淀粉是氢键和静电力的共同作用,羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外,更重要的是与矿物表面金属离子间产生的化学作用,使药剂能牢固地吸附在一水硬铝石矿物表面,增加矿物表面的亲水性,同时,淀粉支链结构的存在,使它能够掩盖吸附的捕收剂,达到抑制一水硬铝石的目的。

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.
