Details of this product

Magnetite Beneficiation Technology

A single magnet ore, mainly sedimentary metamorphic ore type magnet.For the most part iron ore mineral is magnetite, give priority to with the fine grained disseminated;The gangue minerals are mainly quartz or hornblende silicate minerals, etc.Some contain iron silicate more, this kind of ore beneficiation production history, the longest due to mineral composition is simple, often with weak magnetic separation method.When grinding particle size is greater than 0.2 mm, often using a grinding magnetic first;Less than 0.2 mm, the adoption of two pieces of magnetic separation.If the coarse grinding can identify qualified tailings, takes the stage grinding magnetic separation.Water shortage area, then use dry grinding dry magnetic separation, has been depleted rich magnet magnet or lean ore, ore generally use dry magnetic separation to eliminate the gangue, the former get massive rich ore;After all the grinding magnetic separation concentrate.In order to obtain the high grade concentrates, can be in reverse flotation of magnetite concentrate or shock method such as fine screen processing.In order to improve the recovery rate, may consider further recovery techniques such as tailings reelection.

Magnet containing polymetallic ore, general united by weak magnetic separation and flotation process, which is weak magnetic separation recycling iron, flotation recovery sulfur or apatite, etc.Principle process is divided into weak magnetic separation and flotation and flotation – magnetic separation, the two kinds of process of magnetite and sulfide even had body where is different, the previous process, even had body mainly into the iron concentrate;After a process, the main into sulfide concentrate, therefore, under the same grinding granularity, choose after floating magnetic flow can contain low sulphur iron concentrate and recovery rate high sulfide concentrate.

Hematite Beneficiation Technology

separation recovery of magnetite, gravity separation, flotation and magnetic separation recycling of weakly magnetic iron ore series process, use morer in recent years.This is because the weak magnetic separation recovery of magnetite economic and effective than other methods, but most mining by magnet – hematite stone gradually turning processing magnetite ore.This process, the weak magnetic separation and flotation, flotation – weak magnetic separation and magnetic separation – gravity separation has been used in production.Weak magnetic separation and magnetic separation and magnetic separation and magnetic separation and gravity separation is also a factory.Through production practice, the weak magnetic separation and flotation process, tend to put the flotation in weak magnetic separation, before production is more stable, easy to operation management;For weak magnetic separation and gravity separation process, trend Yu Gaicheng weak magnetic separation and magnetic separation or weak magnetic separation and magnetic separation – gravity separation process.

Iron Ore Processing Equipment

1. The ore crushing

Mine usually use coarse broken, broken and fine broken in three sections of broken ore crushing process.Coarse broken multi-purpose 1.2 m or 1.5 m gyratory crusher, broken in use of 2.1 m or 2.1 m standard cone crusher, fine broken by 2.1 m or 2.2 m short head cone crusher.By coarse broken ore, its fragmentation is not greater than 1 m, and then through the medium and fine crushing and screening ore particle size is less than 12 mm grinding groove of the final product.

2. The grinding process

Iron ore grinding process, most of the grinding process, two pieces of small and medium-sized concentrator with a grinding process.Due to the adoption of fine screen and then a new technology, in recent years some concentrator has two grinding into three sections by grinding.Adopting grinding equipment is generally small, the largest 3.6 m×6 m, ball mill most stick mill 3.2 m×4.5 m, the largest since the mill 5.5 m×1.8 m, pebble mill 2.7 m by 3.6 m.After grinding classification is basically the use of spiral classifier.In order to improve the efficiency, part of the concentrator of hydrocyclone to replace spiral classifier.
