A brief introduction to manganese ore

There are more than 150 kinds of manganese ores in nature, such as pyrolusite, silicon mica, manganese oxide, brownstone, greenstone and rhodochrosite, which contain 50-70% Mn.

According to the following three classification methods, manganese ore can be divided into:

  1. 1according to the formation of the deposit: sedimentary, metamorphic and weathering type;
  2. 2according to the iron and manganese content in the ore: manganese ore and ferromanganese ore;
  3. 3according to industrial use: metallurgical and chemical manganese ore.

The top five manganese mining countries in the world include South Africa, Australia, China, Gabon and Brazil. Historically, the demand for manganese has increased following the production of steel and it is expected that this will also be the case in the future.

The following figure shows the global output of different grades of manganese ore. The low-grade manganese ore accounts for a large proportion, so the manganese ore beneficiation technology, which is very important for low-grade manganese ore, will be introduced in the next part.

Manganese ore beneficiation technology

Low-grade manganese ore cannot be directly used in industrial production due to high impurity content, thus there is a need for a method of enriching low-grade manganese ore. Manganese ore processing plant is used to separate valuable minerals from impurity content by physical or chemical properties.

After continuous practice, the density, magnetic and floatability differences between manganese ore and gangue were found.

Based on these differences, the suitable processing plant for manganese ore is the mechanical selection (including washing, sieving, re-election, strong magnetic separation and flotation), as well as fire enrichment and chemical beneficiation.

The following table shows the suitable beneficiation methods for different types of manganese ores:

Among them, due to the simple operation, easy control and strong adaptability of magnetic separation, it can be used for various manganese ore sorting, and has dominated manganese ore processing.

Main equipment and usage of manganese ore processing plant

The following will introduce the main manganese ore beneficiation plant and its production process in detail, including the crushing process, grinding process and beneficiation process.

Major equipment

There are many types and sizes of equipment in the whole manganese beneficiation process. The major equipment is as follows: vibrating feeder, PE jaw crusher, cone crusher, vibrating screen, pendulum feeder, ball mill, spiral classifier, high frequency sieve, magnetic separator, concentrator, filter, dryer, etc.

The general process of the manganese processing plant is like this: crushing process — grinding process — separation process, ie manganese ore — vibration feeder — jaw crusher — cone crusher — vibrating screenpendulum feeder — ball mill — spiral separator — magnetic separator and so on.

The case of manganese ore production line

The manganese minerals in an India manganese ore beneficiation project is mainly composed of rhodochrosite and calcium rhodochrosite.

The entire magnetic separation production line we configured for it has the following characteristics:

  1. 1The two-stage grinding process is adopted, which can not only reduce the mud ore caused by over-grinding of minerals, but also improve the output and achieve the required grinding fineness;
  2. 2One magnetic separator is used for the first stage of beneficiation. In the second stage, one magnetic separator is used for rough selection and another for ore concentrate. The final grade of manganese concentrate is 38% and the recovery rate is 74%.

Manganese ore beneficiation plant manufacturer

For the beneficiation of manganese carbonate ore, manganese oxide ore, mixed manganese ore and polymetallic manganese ore, Fote Heavy Machinery can produce jaw crushers, high-pressure roller mills, rod mills, ball mills, graders, etc for the production of coarse, medium and fine particles at home and abroad.

Our company can provide customers with complete beneficiation process plans and ore dressing experimental equipment in crushing, screening, drying, grinding, wet weak magnetic separation, wet magnetic separation, etc.

We can also provide feasible suggestions for the construction of the beneficiation plants with reasonable price.Contact us
