A new Integrated Manganese Beneficiation Plant of 0.50 million Tons capacity is comiming up at Balaghat Mine for processing Run of Mine. The plant shall be using a most modern continuous jigging plant imported from South Africa, M/s Batman. The total recovery of ore will improve from 55% to 75% after commissioning of plant.
Manganese oxide ore often contains a lot of slime and fine ore, the production of washing – re-election method. Ore the Jingxi ore remove the slime net proceeds of mines, and some can be used as the processed ore, some need to use a jig and shaking re-election. Manganese ore beneficiation process, the overflow of washing is sometimes also need to re-election or high intensity magnetic separation method for further recovery. Some deposition native oxide manganese ore, mining dilution, used in the production of heavy medium and jig re-election to remove gangue, massive concentrate.
In iron oxide manganese ore, iron minerals main contains limonite. Iron and manganese with difficult re-election, flotation or strong magnetic separation, reduction roasting. Industrial washing – to restore the roasting process – re-election. Manganese ore is divided into the manganese oxide, manganese carbonate, associated with various types of multi-metal manganese ore, different types of manganese ore beneficiation and mineral processing equipment is different, selected according to the nature and structural characteristics of the ore beneficiation of manganese ore and The processing equipment is the basic guarantee for the processing plant put into operation profitable.
Oxidation of manganese ore beneficiation
Oxidation of manganese ore beneficiation process and weakly magnetic iron ore beneficiation is basically the same general method of processing by high intensity magnetic separation, re-election.
1. high intensity magnetic separation
One kind if the magnetic minerals, manganese ore is satisfactory concentrate grade using high intensity magnetic separation methods and equipment available, but requires that the higher the magnetic field strength of the high intensity magnetic separation equipment, the general surface of the magnetic field required up to more than 12,000 Gauss. High Intensity Magnetic Separation of manganese ore is generally dry high intensity magnetic separation, manganese dry high intensity magnetic separation using a fully enclosed structure, work process does not produce dust, effectively improve the working environment of workers, the aircraft is simple, easy maintenance, is the ideal equipment for dry type for manganese.
2. the re-election
Of manganese oxide ore and waste rock specific gravity difference, through the re-election can get a good dressing, beneficiation advantage of the re-election of efficient, energy saving, environmental protection, oxidation used in the beneficiation of manganese ore re-election equipment, jig, jig can handle a larger particle size of manganese ore, in order to obtain massive manganese ore, beneficiation of the jig is your ideal choice. Jig the largest selected particle size 50mm and effective solution to the coarse-grained oxide of manganese ore beneficiation, and the dressing effect, the beneficiation indicators have reached a satisfactory level.
Carbonate manganese ore beneficiation
Carbonate manganese ore beneficiation most of the high intensity magnetic separation, heavy media beneficiation and flotation methods. Sedimentary manganese ore containing sulfuric acid commonly used carbonaceous shale, pyrite, and the order of the manganese mineral flotation processes. Hydrothermal manganese ore containing lead and zinc carbon commonly used flotation – strong magnetic separation process. Some sulfur-rich manganese ore, manganese mineral sulfur manganese, roasting methods commonly used in addition to sulfur. Some rich carbonate manganese ore production finished ore roasting method to remove volatile components.
The oxidation of manganese ore beneficiation in order to re-election. Weathered oxide ore often contains a lot of slime and fine ore, the production of washing – re-election method. Ore the Jingxi ore remove the slime net proceeds of mines, and some can be used as the processed ore, some need to use a jig and shaking re-election. Washing overflow sometimes also need to further re-election or high intensity magnetic separation methods such as recycling. Some deposition native oxide manganese ore, mining dilution, used in the production of heavy medium and jig re-election to remove gangue, massive concentrate.
Manganese ore beneficiation equipment
In general, manganese ore beneficiation equipment includes wheeled sand washing machine, spiral sand washing machine and trough-type washing machines. Washing operations often associated with screening, such as the shaker directly flush cleaning or washing machine ore (Net mine) sent shaker screening. Screening can be as an independent operation, the separation of different particle size and grade of product supply for different uses. The choice of manganese crusher machine: hammer crusher, impact crusher, jaw crusher, cone crusher, coarse crushed ore from initial ore, broken, broken bits and so on. Screening, grading and other operations according to the demand to enter the mill after the ore after crushing, grinding, up to a certain degree of fineness, the fineness standards, then return to the ball mill to continue grinding. Grinding to meet the requirements to enter the manganese ore beneficiation equipment, magnetic separator flotation machine for magnetic separation and flotation, can be one or several magnetic separation and flotation. Zenith machinery as a professional manganese ore processing equipment manufacturer, has strict demands on themselves, and strive to improve production technology, and bold in product development and innovation, to the best product to win praise from the market.
