有机黏结剂强化铁精矿的成球性能
通过造球试验、红外光谱分析、动电位测定、接触角测量和黏度测定研究了有机黏结剂提高磁铁矿精矿球团强度的效果及作用机理.结果表明,以瓜尔胶(Guar)为黏结剂时湿球强度最大,羧甲基纤维素(CMC)次之,羧甲基淀粉(CMS)最小;干球强度则与黏结剂用量成显著正相关.红外分析表明,CMS和CMC主要通过羧基和羟基吸附在铁精矿表面,Guar主要通过羟基吸附在铁精矿表面.CMS和CMC使铁精矿表面电负性增强,Guar使其电负性减弱;三种有机黏结剂吸附在磁铁矿精矿表面,皆使其表面接触角减小,亲水性增强.黏结剂浓度相同时,溶液黏度越大,湿球强度越大....

Abstract_FL | Binding effects and mechanisms of organic binders on the magnetite concentrate have been investigated by pelletizing test,FTIR analysis,measurements of zeta potential,contact angle,and binder solution viscosity.Results indicate that wet strengths of pellets with guar gum are the largest,followed by CMC and CMS.Furthermore,it presents a significant positive correlation between the dosage of organic binders and dry pellet strengths.FTIR analysis illustrates that CMS and CMC can adsorb onto the magnetite concentrate by carboxyl methyl and hydroxyl,while the adsorption of guar gum onto the magnetite concentrate is mainly through hydroxyl.Meanwhile,CMS and CMC can increase the negative charge of the magnetite concentrate surface,while guar gum reduces that of the magnetite concentrate.Besides,the adsorption of organic binders on the magnetite concentrate decreases the contact angle and increases the wettability of the magnetite concentrate with water.Results also show that the bigger the viscosity of the binder solution is,the higher the wet strengths of the magnetite concentrate pellets are under the same binder concentration. |
