Iron removal method for filter mud generated during pyrophyllite beneficiation
The invention belongs to the technical field of pyrophyllite processing, and particularly relates to an iron removal method for filter mud generated during pyrophyllite beneficiation. The iron removalmethod comprises the following steps: S1, crushing and grinding raw pyrophyllite ore by adopting a continuous wet ball mill; S2, feeding the screened raw pulp into a flat-plate type permanent magnetic separator; S3, feeding roughed ore pulp into a high-gradient magnetic separator; S4, pouring finished ore pulp into a tray, and putting the tray into an electric heating constant-temperature blast drying box for drying; S5, taking out pyrophyllite pulp blocks in the tray, and grinding the pyrophyllite pulp blocks in a grinding machine; S6, sieving pyrophyllite ore powder; S7, uniformly mixing pyrophyllite tailing powder with chlorine salt, and pouring the obtained mixture into grinding equipment; and S8, feeding the mixture into calcining equipment, conducting calcining for 2-3 hours at a constant temperature, then taking out a calcined material, and carrying out natural cooling to obtain a finished product. According to the invention, a pyrophyllite raw material with a lower iron content can be obtained by performing iron removal operation on pyrophyllite in a manner of combining double magnetic separation and calcination.
本发明属于叶蜡石加工技术领域，尤其涉及一种叶蜡石选矿滤泥除铁方法，包括如下步骤：S1、将叶蜡石原矿进行破碎磨矿，磨矿采用连续湿式球磨机；S2、将筛分好的原矿浆送入平板式永磁磁选机；S3、将粗选矿浆送入高梯度磁选机；S4、将精选矿浆倒入托盘中，将托盘放入电热恒温鼓风干燥箱中干燥；S5、将托盘中的叶蜡石料浆块取出后，放入研磨机中研磨；S6、将叶蜡石矿粉过筛；S7、将叶腊石尾矿矿粉与氯盐混合均匀后，倒入研磨设备中；S8、将混合物送入煅烧设备中恒温煅烧2‑3小时，然后将煅烧后的物料取出，自然冷却后就可以得到成品。本发明通过采用双重磁选与煅烧相结合的方式对叶蜡石进行除铁操作，可以获得铁含量更低的叶蜡石原料。
