以NM?3为分散剂，针对东鞍山含碳酸盐中矿进行了分散浮选试验研究，确定了最佳分散浮选的工艺条件，即控制pH值为12．0，分散剂NM?3用量为200 g／t，抑制剂淀粉用量为1400 g／t，活化剂氧化钙用量为400 g／t和捕收剂KS?Ⅲ用量为800 g／t，经一粗一精分散浮选闭路试验获得了铁精矿品位为62．32％、回收率为42．57％的良好指标。分散浮选不仅流程简单，而且获得了良好的指标，为利用含碳酸盐中矿奠定了技术工艺基础。
以NM?3為分散劑，針對東鞍山含碳痠鹽中礦進行瞭分散浮選試驗研究，確定瞭最佳分散浮選的工藝條件，即控製pH值為12．0，分散劑NM?3用量為200 g／t，抑製劑澱粉用量為1400 g／t，活化劑氧化鈣用量為400 g／t和捕收劑KS?Ⅲ用量為800 g／t，經一粗一精分散浮選閉路試驗穫得瞭鐵精礦品位為62．32％、迴收率為42．57％的良好指標。分散浮選不僅流程簡單，而且穫得瞭良好的指標，為利用含碳痠鹽中礦奠定瞭技術工藝基礎。

With NM?3 as dispersant, dispersion flotation tests were carried out with Donganshan carbonate?containing middlings, with the optimum dispersion flotation conditions obtained as follows: pH=12. 0, with NM?3 as dispersant ( 200 g/t) and starch as inhibitor ( 1 400 g/t) , CaO as activator ( 400 g/t) and KS?Ⅲas collector ( 800 g/t) . Adopting a closed?circuit flowsheet of one roughing and one cleaning, an iron concentrate with TFe grade and recovery of 62.32%and 42. 57%, respectively, can be prepared. Dispersion flotation technique with simple process, can bring good beneficiation index, thus paving a foundation for future better utilization of carbonate?containing middlings.
