Introduction of Manganese Ore

Manganese ore is concentrated in many provinces (regions) such as Chongqing, Guizhou, Guizhou, Hunan, and Jiangxi. Especially, Gui and Hunan are rich in resources, accounting for about 65.4% of China's total reserves. About 90% -95% of mines are used in the iron and steel industry. In addition, they are also widely used in chemical, light industry, building materials, national defense, electronics, environmental protection and other fields, which play an important strategic role in the development of China's national economy.

There are many methods available for manganese ore beneficiation, including mechanical beneficiation (screening, sieving, reselection, flotation, etc.), chemical beneficiation, and fire enrichment. Among them, the flotation method is commonly used and has considerable effects Most of the manganese ore processing plants are selected, so what are the manganese ore beneficiation (flotation) production line equipment? What is the process? This article will give you a brief introduction.

Manganese ore beneficiation production line

The manganese ore beneficiation production line is a production line that processes the manganese ore mined from the mine to improve the quality of the manganese ore. The manganese ore production line is not a single or several equipment, but a production line formed by the combination of a set of manganese ore beneficiation equipment It has the advantages of energy saving, high efficiency, environmental protection, and high degree of automation. It is suitable for large and medium-sized manganese ore beneficiation plants and has good beneficiation indexes for the manganese ore such as manganese oxide and manganese carbonate. SBM Machinery is a professional manganese ore beneficiation equipment manufacturer. Our factory has very rich practical experience in the design and construction of manganese ore beneficiation production line. Here we briefly introduce the process flow and equipment configuration of the manganese ore beneficiation plant for reference!

The beneficiation method of manganese ore is mainly the gravity separation method, followed by the strong magnetic separation method and the flotation method. The gravity separation method occupies half of the country in the field of manganese ore beneficiation and is applicable to the beneficiation of most manganese oxide ore and some manganese carbonate ore. The strong magnetic separation method is only used as an auxiliary process of the reselection process for recovering manganese minerals with a high degree of oxidation at a fine particle level. The flotation method is only used for the beneficiation and purification of some manganese carbonate ore. In contrast, the market share of strong magnetic separation and flotation is relatively small. The production line of manganese ore reselection is introduced here.

Manganese ore re-selection production lines generally include crushers, vibrating screens, jigs, dewatering screens, and sometimes equipment such as ore washing machines. The raw ore must be crushed so that the particle size of the manganese ore can be controlled within the range of the effective selection particle size of the reselection equipment before washing. Therefore, the crushing equipment in the manganese ore beneficiation production line is essential. After crushing and sieving manganese ore with small mud content, it can directly enter the re-selection process, but for manganese ore with large mud content and strong viscosity, it needs to be washed and washed after crushing. With a lot of cohesive soil, the material after crushing and washing needs to enter the sieving process for sieving and grading, because the gravity size control of the manganese ore by the gravity separation equipment is very strict. It often results in a reduction of the beneficiation index, so the screening process is also an essential process in the manganese ore beneficiation production line. After crushing, screening, and washing, the manganese ore enters the corresponding silo for storage. Under the silo, a feeder device that can automatically feed should be set to ensure that the manganese ore can be evenly fed into the gravity separation equipment for washing. To get the best beneficiation effect. The manganese ore concentrate and tailings after being washed by the jig are discharged out of the machine with a large amount of water. If they are to be directly sent to the concentrate or tailings plant, they must be dewatered. Therefore, after the jig, The installation of dewatering screens and other equipment is also very important for the automation of the manganese ore beneficiation production line. Designing a reasonable manganese ore beneficiation process and equipment configuration according to the actual situation is crucial to the establishment of a manganese ore beneficiation production line. The following is a manganese ore beneficiation production line designed by SBM Machinery for Malaysian customers:

For decades, the gravity beneficiation method has been the mainstream method of manganese ore beneficiation. Therefore, the manganese ore beneficiation production line industry is mostly a manganese ore beneficiation production line. , Washing machine, vibrating screen, jig, dewatering screen and other equipment, reasonable combination of these equipment to establish an automated manganese ore beneficiation production line has become the ultimate purpose of large and medium-sized manganese ore beneficiation plant. In order to ensure the rationality and efficiency of the manganese ore beneficiation production line, SBM Machinery specially set up a small test platform that can carry out small-scale manganese ore washing tests for customers free of charge and design reasonable ore dressing process and equipment configuration.

Manganese ore beneficiation production line process

First, the mined bulk manganese ore is crushed by a jaw crusher, and then reasonably sieved into a variety of different specifications by a circular vibrating screen. Unqualified fragments are sent back to the jaw crusher for re-crushing; qualified stones are mixed with water and then crushed. It is evenly sent to the wet grinding treatment in the ball mill, and then classified by the spiral classifier. Similarly, the stones that do not meet the fineness requirements will be returned to the ball mill to continue grinding; the ore pulp that meets the conditions will be sent to the mixing bucket and added to the corresponding The medicine is stirred well and sent to the flotation machine for full reaction. After that, the manganese concentrate with higher purity can be obtained, and then it is concentrated into the concentrator for efficient concentration, and the mash is sent to the dryer for drying and dehydration. In addition, you can also use natural air drying method to achieve dehydration effect.

Manganese ore is widely used in the economic field and is an important raw material for metallurgy and many industrial sectors. "Manganese-free does not make steel", the saying "" reflects the important status of manganese. Due to the complex composition of manganese minerals, only concentrates separated through beneficiation can be better applied to the production sector. So what are the manganese ore beneficiation (flotation) production line equipment? What is the process? Let's find out below.
 

The main equipment used in the manganese ore beneficiation production line includes jaw crushers, ball mills, and flotation machines. In addition, it also includes auxiliary equipment such as screw classifiers, mixing barrels, thickeners, and dryers. The following is a brief introduction to important equipment.

1. Jaw Crusher: This equipment is used to complete the crushing operation of manganese ore. We use 30 years of technical precipitation and introduce European innovative technology design. It has significant advantages and characteristics:

2. Ball mill This equipment is a one-step grinding process for the crushed manganese ore. It consists of a feeding part, a discharging part, a turning part, etc., and has very good product advantages:
