摘要
研究了抑制剂Ｎａ２ＳｉＯ３对稀土浮选的影响，结果表明，ｐＨ值在８．５～９．５范围内，Ｎａ２ＳｉＯ３的抑制作用最好，Ｎａ２ＳｉＯ３抑制作用随其模数增大而加强，Ｎａ２ＳｉＯ３用量增大捕收剂Ｈ２０５用量需相应增大。
The effects of the depressant——Na_2SiO_3 on flotation of rear earth were studied,the results show that the optimum pH of depression effect of Na_2SiO_3 is 8.5～9.5,and the depression effect of Na_2SiO_3 can be enchaced with the addition of its modulus,and the consumption of Na2SiO3increase with what of the collector——H205.
