Iron ore dressing technology

Magnetite ore dressing mainly use magnetic separator for sorting of low grade magnetite.Due to the strong magnetic ore,it is good wear and good election,Domestic magnetic separation plants use stage grinding and multi-stage grinding process,the coarse grained dissemination magnetite use the former process(one stage grinding),fine particle and micro-fine particle-disseminated magnetite using the latter (two or three stage grinding);Weakly magnetic iron ore dressing, is mainly used for separation of hematite, limonite, hematite, siderite, hematite or mixed ore,the so-called "Red Rock".Grade of this kind ores is low,they have fine dissemination size, complex mineral composition,difficult sorting. rotary kiln jaw crusher
dressing technology for roasting, wet high intensity magnetic separation, weak magnetic flotation, and the gravity concentration process,Equipment and new varieties of pharmaceutical research improve continuously, so that the concentrate grade, metal recovery improve continuously.Such as the concentrator use weak magnetic - magnetic - flotation process.

Iron ore dressing mainly give priority to magnetic separation,While the basic requirement is the Mineral magnetism, Magnetite can be directly obtained iron ore concentrate after magnetic separation,If it is hematite limonite ore or the other in order to get more than 65% grade iron concentrate,We must through magnetization roasting magnetic separation for the reduction of magnetite,Higher levels of impurities in the ore such as hematite, it is necessary that reduces impurity through the flotation. ball mill rotary kiln ball mill manufacture
