How to Beneficiate The Low-Grade Specularite

Iron ore is the main raw material for steel industry. Simple and easy to choose the magnetite iron as raw material in early stage, but with the increasing scarcity of mineral resources, hematite, limonite, specularite and other weak magnetic iron ore were not taken seriously in the past has gradually been developed and utilized. Especially specularite, in recent years, has been fully utilized, there are many customers inquire how to beneficiate the low-grade specularite, in this Forui machinery will tell you about the technology and equipment of low-grade specularite for reference.

As the raw materials, specularite's grade must meet certain requirements to get into the smelting furnace, and a native of specularite often have other associated gangue so that the taste can't meet requirements, it is necessary to do beneficiation and purification of specularite before industrial smelting, low-grade specularite must be purified by beneficiation methods.

Beneficiation method of specularite is gravity separation, followed by reduction roasting magnetization. Gravity separation is based on the difference of proportion of specularite and gangue, and it has energy efficient, environmentally friendly, investment and other advantages, suitable for beneficiation of coarse-grained disseminated specularite. Magnetic roasting is applicable to disseminated, there is no clear boundaries between iron minerals and gangue, for the specularite with very uniform distribution, magnetic roasting method has high production costs, low beneficiation efficiency, large investment in equipment. In the increasingly shrinking profits today, magnetization application roasting method in weak magnetic fields of iron ore beneficiation less and less, have been replaced by other methods of beneficiation trend.

In fact, most of specularite is coarse-grained disseminated type, iron mineral and gangue‘s distribution and boundaries is very clear, and specularite’s proportion is much larger than the proportion of gangue, thus gravity separation's application of law in the field of ore dressing mirror is also very much, especially in Xinjiang, Hainan and other places of coarse-grained disseminated specularite, gravity separation is almost as beneficiation methods use only commonly used equipment for gravity separation jig.

For purification of low-grade specularite trapezoidal keystone jigger and large particles jigger, jigger can effectively sorting specularite and its associated gangue, and good dressing effect, high efficiency beneficiation low cost beneficiation, favored by more and more concentrator. Gongyi Forui Machinery has provided the entire beneficiation process and device configuration for Xinjiang, Hainan and other places of specularite concentrator , accessed to the ideal dressing effect.

Gongyi Forui Machinery is a professional manufacturer of jigger, we have a very rich experience of low-grade specularite, and free for customers take specularite beneficiation test design process and device configuration.
