查询词典 iron ore

Process of flotation of acture ore is the following: firstly, adding Na_2CO_3, ZnSO_4, CSU-1 to the pulp while grinding, and thus in this condition of low Eh, marmatite is inhibited; Secondly, adding CSU-1 to the pulp out of grinding machine, then amesonite and iron sulfur mineral can be flotated using diethyldithiocarbamate as collector; High quality lead and antimony concentrate can be got by adding CSU-1 and calcareousness; Lastly, marmatite is flotated by adding calcareousness, CuSO_4, xanthe, and D-250 to get zinc concentrate.

小型试验研究表明，首先在脱硫粗选作业只加入适量的Na_2CO_3、ZnSOO_4、和CSU-1至磨矿机，利用磨矿机的研磨和磨机中的低电位环境，使铁闪锌矿受到抑制，而最容易浮的脆硫锑铅矿和黄铁矿、磁黄铁矿等硫化矿物则依然具有可浮性；在磨机出来的矿浆中分别加入CSU-1进一步抑制易浮的铁闪锌矿，然后加入乙硫氮将脆硫锑铅矿和硫化铁矿快速浮净，加入石灰和CSU-1，浮选分离出高质量的铅锑精矿；接着添加石灰、CuSO_4、黄药及2~#油选别铁闪锌矿。
