Manganese ore beneficiation equipment is mainly determined based on the properties of manganese ore and the manganese ore beneficiation process, including flotation equipment, gravity separation equipment, magnetic separation and other equipment. In addition, there are pre-selection equipment, post-selection dehydration equipment, etc. The specific equipment types are as follows:
Manganese ore flotation equipment is mainly suitable for processing fine particles Or fine-grained manganese minerals can be separated from gangue minerals by using chemicals and the floatability of minerals. The main used flotation equipment is: SF type, JJF type, XCF type, KYF type and BF type.
KYF type: Suitable for roughing and fine selection in medium and large manganese ore dressing plants;
JJF type/XCF type: Suitable for roughing and sweeping operations in medium and large manganese ore concentrators;
BF type:Suitable for roughing and beneficiation operations in medium and small manganese ore concentrators.
Gravity separation equipment is mainly suitable for processing silicon-containing substances in manganese ore (such as SiO2) minerals, and coarse-grained manganese minerals (but not required for other industrial joint separations. Such as: gravity-magnetic or gravity-flotation separation, etc.). The main application equipment for gravity separation is: jig, shaker, cyclone, etc.
Jig: Suitable for processing coarse-grained manganese minerals, it has a good effect on desilication, and can also remove some iron substances;
< strong>Shaker/Cyclone:Suitable for processing fine-grained manganese minerals.
Manganese ore often contains iron (iron oxide) impurities. At times, strong magnetic separation is often used to remove iron. The main equipment used is: wet strong magnetic separator, high gradient magnetic separator and dry strong magnetic separator.
Wet magnetic separator/high gradient magnetic separator: Mostly used for iron removal of fine-grained ferromanganese minerals;
Dry magnetic separator Selector:Suitable for iron removal from coarse-grained manganese iron ore.
Manganese ore The main purpose of the pre-selection equipment is to crush the manganese minerals to a certain particle size to facilitate subsequent selection. The equipment is mainly crushing equipment, screening equipment, grinding equipment and classification equipment.
Crushing equipment: There are jaw crushers for coarse crushing and cone crushers for fine crushing;
Screening equipment: Self-centering vibrating screen is used for fine particle screening, and circular vibrating screen is used for coarse particle screening;
Grinding equipment: Grid type ball mill is used for coarse grinding operation, and overflow ball mill is used for coarse grinding operation. Do fine grinding operations;
Classification equipment: Spiral classifier is used with grid-type ball mill for coarse particle classification, and hydrocyclone (group) is used with overflow type for fine grinding and classification.
Manganese ore dehydration equipment can be divided into two categories, one is manganese concentrate dehydration, and the other is manganese tailings dehydration. According to its dehydration requirements, commonly used concentrators are , dewatering screens, cyclones, filter presses and filters.

Concentrator: Suitable for concentrate/tailings dehydration. One more stage of dehydration is done in the concentrate and two stages of dehydration are done in the tailings. The low flow concentration is 60~70%;
Dehydration screen: Mostly used for tailings dehydration, used in three-stage dehydration operations to make the final moisture content of the tailings between 12 and 15%;
Cyclone flow Filter:Used in the first stage of dewatering in tailings dewatering, the low flow moisture content is 40~30%;
Filter press/filter:Can be used Dehydration of concentrate/tailings is mostly used in the final stage. The moisture content of the slurry is lower than 9~12%.
The above is an introduction to common manganese ore beneficiation equipment. Which type of equipment needs to be used in each link depends on its processing capacity. Which type of equipment should be used in which link depends on the required requirements.
