MagnesiteMining Equipment and Open Pit Quarry Plant for Sale

Magnesiteexploitation can be operated by open pit mining and underground mining methods.SBM provides complete series of undergroundmagnesitemining equipment and open pit quarry plant for sale.

MangnesiteOre Deposits

China has the world's richestmagnesite resources.The total magnesiteore reserves are 3 billion tons, ranking No. 1 in the world. One important feature of Magnesite is not widely distributed;the reserves are relatively concentrated in some region. Magnetiste is primarily used as refractories, also for preparing compounds of magnesium and extraction of magnesium metal. Other major producers of magnesite ore in the world include the former Soviet Union, North Korea, the Czech Republic, Yugoslavia, Austria,Australiaand Greece and other countries.

Magnesite Mining Methods

In early time, magnesitemining exploitation started with open pit mining, but due to higher quantities demanded and the increase in thickness of the overburden.When deposits are difficult to reach from the surface (depth, cliffs permitting side access), the only alternative is underground workings. Currently some 90% of thetotal production is produced in underground mining. There are both open pit mining plant and underground mining equipment for magnesite in the world market.

Pillar mining system withuncemented backfilling is often used for magnesite mining operation.The main advantage of this mining method is the high flexibility for quality control. The bigdisadvantage is that the support of the roof is destroyed when taking the nexthanging wall. New support then has to be installed to protect the miners.This mining method has proven high efficiency up to an overburden of some 700 m. If theoverburden is higher than that, the pillars have to be redesigned due to higher stresses and theincreased risk of rock fall.

Magnesite Mining Equipment

In magnesite mining applications, the extracted magnesite will go through several processing operation, such as extraction, crushing,grinding, screening, separation etc. Crushing between jaw crushers or rollers crushers is the normal practice, followed by coarse screening to produce half to one inch lumps for gravels etc. Further crushing and screening yields smaller pieces, particularly 3/8 inch, 1/4 inch, and 3/16 inch, cleaned by passing over trommels.

SBM has been dedicated in mineral mining and processing technology for several decades. With know-how technology, we developed the state-of-art magnesiteminingequipment for sale, such as jaw crusher, impact crusher, cone crusher, mobile crusher, ball mill, ultrafine mill, vibrating screen, classifier, magnetic separator, flotation separation machine etc. SBM experts can do ore experiments and analyze the ore properties, and customize suitable mining solution according to specific requirements.

MagnesiteOpen Pit Quarry Plant

Open pit mining methods requires low cost than underground mining method, if the magnesite ore deposit is not so deep. Magnesite ores are produced by open pit mining by developing benches up to 7.5 m height. Mining activities in open pits may be divided into five main stages such as overburden removal, drilling, blasting, loading, and transporting to magnesiteopen pit quarry plant. Enrichment of raw magnesite minerals from open pit can be divided into the following main operations: screening, crushing, sizing, and concentration, and most of these operations are widespread to the production of sized aggregates and ores.

In magnesite open pit quarry plant, the following several main types of machines are involved:
Crushing plant: jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, gyratory crusher and cone crusher for tertiary crushing.
Grinding mill: ball mill, high pressure mill, ultrafine mill, vertical roller mill, trapezium mill, raymond mill etc.
Auxiliary machine: vibrating screen, belt conveyor, sand washing machine, drying plant etc.

SBM not only provides high quality equipment, we also provide whole range of consulting service and training service including mining technology, design, installation, operation, maintenance etc. We aim for providing high advanced equipment and create more wealth for customers.
