Hematite mining equipment

Magnetic beneficiation process

The haematite's another name is red iron ore,and its chemical structural formula is Fe203. it's a weak magnetic iron ore and the floatability is better than magnetite. And it is a main material of ironmaking. The main beneficiation process includes:gravity separation,floatation,strong magnetic beneficiation or mix several beneficiation process,and another process is magnetization roasting and then weak magnetic separation. The early haematite beneficiation mostly used the gravity separation process,and the main machines are:jigger,centrifugal separator,spiral chute,spiral washing machine,shaking table etc.

Because some other beneficiations's production capacity was small,the grade after processing was low,recovery ratio is low and then was dumped as time goes on. Later as the haematite beneficiation developing,the floatation process ans high intensity magnetization process. It mainly use oxidized paraffinum sodium salt as the collector for floatation and electromagnetic strong magnetic separator as beneficiation equipment for strong magnetic separator. But the others beneficiation technology target were all not good enough. These latest years,the beneficiation process of haematite has developed very well. Especially use the high intensity magnetic separation which is can improve the grade of iron ore concentrate very well,and the recovery of Iron ore concentrate is satisfying.

Hematite mining equipment

Hematite( also spelt as haematite), is a kind of oxide of iron, and it is the main ore mineral of iron as well. It has various colors, including black to steel or silver-gray, brown to reddish brown, or red. Although in modern times, iron is gradually replaced by other metals, iron is still the most important metal. Therefore, hematite is one of the most important minerals in economy. While the forms of hematite are various, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral. Hematite is present in the waste tailings of iron mines .

Magnetic separation—flotation is often adopted in some countries when deals with fine and medium dissemination particle of hematite—magnetic mineral, such as China, India, Liberia and Peru, and so on, gravity separation—magnetic separation—flotation is not often used in hematite recovery. Miha Noble Engineering Company develops a new technology of hematite recovery from wet low-intensity magnetic separation tailings under laboratory conditions, and expands the experiment together with Михайловск Mining Company. Expansive experiment proves the techniques process that obtains iron grade of 61.5%~62.7% from tailings of Михайловск Mining Company mineral processing plant, and the possibility of hematite concentrates.

Coal production line

Production Line procedure : The crushed materials will be transferred to the vibrating screen, and separated to different sizes. Those aggregate with suitable size will be transferred to the final product pile and those with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed circuit manifold cycles. The sizes of final products will be graded and separated according to customers' requirements, and the deduster will be attached for the sake of environment protection.

Shenbang is a primary coal mill manufacturer and supplier located in China. In addition to coal mills, we can also provide many other machines for cement production lines, like rotary kilns, pre-crushing equipment, and cooling machines, and more. Highly effective impact fine crushers, concentrators, and steel rolling mills are also available here. These products are welcomed by customers due to their good quality and competitive prices.
