硝基腐植酸钠具有离子交换能力、螯合能力、缓冲能力和亲水性。利用这些性能在磷矿浮选中抑制碳酸盐脉石是一种较好的药剂,试验表明对几种磷矿浮选获得满意的指标。 硝基腐植酸钠制备过程简单,原料来源广,浮选用量少,无污染之害。 经过几年的研究,初步探讨了硝基腐植酸钠抑制作用的机理,从而有利于进一步提高其选择性。硝基腐植酸钠是一种有希望的抑制剂。 一、硝基腐植酸钠的性质及制备 腐植酸是用稀碱液(1～2％NaOH)从泥煤(草炭),褐煤和风化烟煤抽取的物质。经物理和物理化学分析法研究证
Nitrosodium humic acid has ion exchange ability, chelating ability, buffering ability and hydrophilicity. The use of these properties in carbonate rock flotation inhibition of carbonate gangue is a better agent, the test showed that several phosphate flotation obtained satisfactory indicators. Nitro-sodium humic acid preparation process is simple, wide source of raw materials, flotation less, no pollution damage. After several years of research, initially discussed the mechanism of nitric acid humic acid inhibition, which is conducive to further improve its selectivity. Nitrous humic acid is a promising inhibitor. First, the nature and preparation of sodium nitro humic acid Humic acid is diluted with lye (1 ~ 2% NaOH) from peat (peat), lignite and weathered bituminous coal extract material. Physical and chemical analysis of physical evidence
