Abstract

: The complexity of the mineralogical, chemical and exogenous parameters generates a low efficiency of electrical separation of oxidized iron ore. For this purpose, a study was conducted to provide a method for electrostatic separation and to select the chemical reagents. And this, for increasing the contrast of the dielectric separating minerals in the corona discharge field. The reagent-collector used is the auramine with a specific consumption of 0.3 kg/t. Whereas, the reagent depressants is carboxymethyl cellulose mixture with a specific consumption of 0.25 kg/t. From the obtained test results electrical treatment of oxidized iron ore are satisfied for proposed process.

氧化铁矿的静电分离新方法

:由于矿物学、化学和外源参数的复杂性，导致氧化铁矿电分离效率较低。为此，本研究提供了一种静电分离的方法和化学试剂的选择。这是为了提高电晕放电场中介电分离矿物的对比度。所用的捕收剂为金胺，比耗为0.3 kg/t。而试剂抑制剂为羧甲基纤维素混合物，比消耗量为0.25 kg/t。从试验结果来看，电处理氧化铁矿的工艺是满意的。
