基于正交试验的赤铁矿石助磨剂筛选试验研究

摘要

磨矿过程中添加助磨剂会提高磨矿效率,本文应用正交筛选试验设计方法对鞍千赤铁矿石进行了助磨剂筛选试验,并对正交筛选试验设计的结果应用SPSS19.0软件进行分析,确定了影响赤铁矿石磨矿效果的助磨剂.结果 表明:对赤铁矿石磨矿起助磨作用的药剂有:六偏磷酸钠、焦磷酸钠、氟硅酸钠、羧甲基纤维素钠(CMC). NM-3、油酸钠、醋酸铵;助磨效果由好到坏分别为:NM-3,油酸钠,醋酸铵,焦磷酸钠,六偏磷酸钠,CMC,氟硅酸钠;起阻磨作用的药剂为:水玻璃、碳酸钠、聚丙烯酸钠、十二烷基磺酸钠、十二烷基硫酸钠;阻磨效果由好到坏分别为:十二烷基磺酸钠,碳酸钠,十二烷基硫酸钠,水玻璃,聚丙烯酸钠.%In the grinding process adding grinding aids can improve grinding efficiency, this paper applied orthogonal design method of screening test of grinding aids screening test of Anqian hematite ore, and the results of the orthogonal design of the screening test were analyzed using SPSS19.0 software, to determine the impact of hematite ore grinding effect of grinding aids. The results show that the grinding agent of hematite ore from the grinding effect are: six partial sodium phosphate, sodium pyrophosphate, sodium fluoride and sodium carboxymethyl cellulose (CMC), NM-3, sodium oleate, ammonium acetate; grinding effect from good to bad respectively: NM-3, sodium oleate, ammonium acetate, sodium six pyrophosphate, sodium hexametaphosphate, CMC, sodium fluorosilicate; drug resistance has the function of grinding: water glass, sodium carbonate, sodium polyacrylate, twelve sodium dodecyl sulfate, twelve sodium dodecyl sulfate resistance; grinding effect from good to bad were: Twelve sodium dodecyl sulfate, sodium carbonate, sodium dodecyl sulfate twelve, water glass, sodium polyacrylate.
