What is Manganese ore?

Manganese ore is widely existing in the nature, almost all kinds of mineral ores and silicate rocks contain manganese ore. The most common types of manganese ores are anhydrous and hydrous manganese oxide and manganese carbonate. Now there are 150 kinds well-known manganese minerals, but the high grade manganese and can be enriched in a large amount of manganese ore with economic value only has 5-6 kinds. The most important and most valuable kind are the Pyrolusite and hard manganese ore. As well as the Manganese ore, brown manganese ore, manganite and manganite and so on. The content of manganese in these minerals is about 50 ~ 70%, which is an important industrial mineral of manganese.

Chrome ore distribution in the world :

Manganese ore in the world are not only unevenly distributed, but also differ greatly in their ore grades. Manganese rich resources are mainly concentrated in South Africa, Gabon, Brazil and Australia. For example, the manganese ore grade of the Cara Hari mining area in South Africa is 30% – 50%, and the grade of manganese ore in the grout Island mining area of Australia is up to 40% – 50%; India, Kazakhstan and Mexico are middle grade manganese mineral resources. The grade of manganese in the ore is generally about 35%-40%; Ukraine, China and Garner are mainly low. The grade manganese ore is the main type, and the grade is generally lower than 30%. It can only be sold as a commercial ore (more than 35%) through mineral processing and artificial enrichment.

China’s manganese ore production is not low, but it still relies heavily on imports. First, China’s manganese ore resources are of low grade, and the resources available for exploitation are limited; the two is the large demand for manganese ore in China.

Manganese ore Applications:

Manganese ore and its compounds are used in various fields of the economy. The iron and steel industry is the most important field, with the amount of manganese accounted for 90% to 95%, mainly as deoxidizer and desulphurizer in the process of ironmaking and steelmaking, and used to make alloys. The remaining 10% ~ 5% of manganese is used in other industrial fields, such as the chemical industry (making various manganese containing salts), light industries (used for batteries, matches, printing lacquers, soap making, etc.), building materials industry (glass and ceramic colorants and fading agents), national defense industry, electronic industry, and environmental protection and agriculture and animal husbandry, etc. In short, manganese has a very important strategic position in the economy.

Manganese ore type existing in nature :

In the nature, the Manganese ore are existing in various kinds rock, it is free type manganese ore in rock , can be released and separate out after crushing and grinding to specific size. The most common type is rock manganese ore, and some manganese ore are complete free in nature, after washing and gravity separation can recovery it.

How to process Manganese ore with the Manganese ore mining equipment?

The ore dressing technology of Manganese ore mainly has washing , crushing , Media gravity separation and magnetic separation process, the Manganese ore mining equipment are including trommel scrubber washing machine, jaw crusher, hammer crusher, double roller crusher, jig separator, and sometimes will use high intensity magnetic separator to further improve the grade of Manganese ore concentrate.

The selection of Manganese ore mining equipment is closely related to the physical and chemical properties of Manganese ore. Because Manganese is weakly magnetic, with the continuous improvement of high intensity magnetic separation technology, the technology of purifying Manganese ore with high intensity magnetic separation has been very mature. Moreover, because the magnetic separation process has no pollution to the environment, the Manganese ore magnetic separation technology has been popularized and applied in the major mineral processing plants.

JXSC mine machinery Company in China has more than 30 years professional experience at Manganese ore washing plant and Manganese ore mining equipment, design full set Manganese ore process flowchart , provide complete set Manganese ore mining equipment, can send engineer to mine site for Manganese ore mining equipment installation and commissioning guidance. Have already built many Manganese ore processing plant in Africa countries. Include: South Africa, Zimbabwe, Madagascar, Albania, Uganda, China,ect.

Below the flowchart description that JXSC Engineer recommend for the Manganese ore processing plant:

Manganese ore processing plant:
Feeding->washing->crushing->gravity separation ->magnetic separation for upgrading

Manganese ore Feeding: can be vibration feeding machine, feeding hopper, belt feeder, wheel loader or excavator feed directly. Usually will make grizzly bar on vibration feeder or hopper to remove big waste stones firstly. Depends on process capacity to choose suitable manganese ore mining equipment.

Manganese ore Washing: the manganese ore washing machine is for washing clean the clay and mud in raw material, most popular used are manganese ore washing trommel scrubber and manganese ore washing trommel screen. manganese ore trommel scrubber washer is for washing manganese ore raw material that with many sticky clay, manganese ore washing trommel screen is for wash manganese ore raw material that without much sticky clay. Depends on raw material conditions to choose suitable manganese ore mining equipment.

Manganese ore Crushing: usually the Manganese ore feeding material is large size, after washing, need to crush manganese ore to proper suitable sizes, so the manganese ore can be released and separate out by mining equipment. The crusher type can be jaw crusher, fine jaw crusher, hammer crusher, double roller crusher, it depends on feeding size and output size needed to choose proper manganese ore mining equipment crushers.

Manganese ore Gravity Separation: after crush to profer needed size manganese ore, then need go to manganese ore gravity separation process, most common used manganese ore separation equipment is jig separator, this is the best choice of manganese ore gravity mining equipment. The concentrate ore discharged from manganese jig separator can be as final product, if need higher grade manganese concentrate,can send to high intensity magnetic separator.

Manganese ore Upgrading: if need much higher grade of manganese ore , can use high intensity magnetic separator to upgrade it. The manganese ore mangetic separator is also important manganese ore mining equipment for final upgrading.
