摘要
以ＦＤ为选择性絮凝剂，本文对四种分散剂（水玻璃、六偏磷酸钠、氟硅酸钠、酸化水玻璃）分散四种脉石矿物（石英、萤石、方解石、石榴石）的行为进行了研究，并对水中Ｃａ￣（２＋）、Ｍｇ￣（２＋）影响选择性絮凝工艺以及选择适宜调整剂克服水中Ｃａ￣（２＋），Ｍｇ￣（２＋）的影响进行了研究。结果表明：Ｎａ＿２ＣＯ＿８能很好地克服水中Ｃａ￣（２＋）和Ｍｇ￣（２＋）的不良影响，六偏磷酸钠是微细粒黑钨矿选择性絮凝工艺中最佳的分散剂。人工混合矿试验表明：采用最佳药剂制度可使微细粒黑钨矿与四种脉石分离，并取得了令人满意的分选指标。
With FD used as selective flocculant,the dispersion behavier of four kinds of dispersants(sodium silicate(SS),sodium hexametaphosphate(SHP),sodium fluosilicate(SFS),acidized sodium silicate(ASS))for four kinds of gangues(quartz, fluorite, calcite,garnet)has been studied. Moreover,the effects of Ca￣(2+) ,Mg￣(2+) on the process of selective flocculation and the selection of fit regulators used to overcome the counter effects of Ca￣(2+),Mg￣(2+) in water have also been studied. The results showed that the counter ef fects of Ca￣(2+), Mg￣(2+)in water can be overcome by Na_2CO_3 effectively,and SHPis the best dispersant in the process of selective flocculation for wolfra-mite fines.The separation results of manmade mixtures showed that the wol-framite fines can be separated from four kinds of gangues with the best rea-gent system,and the separation results gained are satisfied.
