Mining iron ore process

Iron ores are mostly dark grey to rusty red in color and high specific gravity. Iron ore is the source of primary iron for the world’s iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base.

The process of mining low-grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. The equipment used includes diamond-bit rotary drills, hydraulic shovels and loaders, water wagons, production trucks and heavy-duty conveyors.

Mining iron ore process

Iron ore is upgraded to a higher iron content through concentration. Iron ore is being beneficiated all round the world to meet the quality requirement of Iron and Steel industries. However, each source of Iron ore has its own peculiar mineralogical characteristics and requires the specific beneficiation and metallurgical treatment to get the best product out of it. Several techniques such as washing, jigging, magnetic separation, advanced gravity separation and flotation are being employed to enhance the quality of the Iron ore.

Flotation machine for iron ore

Flotation machines constitute the basic equipment for useful minerals recovery
from non-ferrous ores and other raw materials by flotation. Magnetic separation and flotation are the most widely accepted technologies for the upgrading of iron ore particles, but these processes result in iron concentrate with high amounts of very fine and/or interlocked silica particles.

The Flotation Machine Advantages:
1. Heavy-duty construction
2. Low maintenance
3. Efficient operation
4. Replaceable wear components
5. Single or double overflow

Gold ore crushing plant in South Africa

Rand aurideposit are famous for it is the largest gold producing area of the world. In South Africa, the gold are the top tree mineral for export and it do bring great much interests to South Africa economy. In South Africa, gold ore do attract a number of businessmen. No matter the scale is big or small, gold ore crushers are widely built in South Africa.

Though these years, the gold ore production cost increase a lot, and the gold market is not so bright with the decline of iron ore price. Many investors are still confident of the South Africa gold industry.

South Africa Gold Ore Crushers

Because many largest gold ore deposits are controlled, most investors’ gold ore crushing plant are small scale. The popular gold ore crushers are small jaw crusher, hammer crusher, ball mill and matched sand washing machines and vibrating screens.

The new style hammer crusher is competent to this task very well.
2. The rear frame can be opened for convenient maintenance
3. Separate bottom gate is convenient for adjust the discharge opening size

Ball mill for South Africa gold ore

These hammer crushers well satisfy small scale South Africa gold ore producers. Meanwhile, ball mill are very popular, too. It can easily ground the gold ore to small particles. At the bottom of ball mill, one wire mesh is installed, so it separates the qualified ones directly before discharging them from the machine. Actually, ball mills are widely used in sorts of South Africa mining ore beneficiation plants. Such as tin ore beneficiation plants, iron ore dressing plants, manganese ore processing plants, etc. It is really a high performance and price ratio mining processing equipments.

200TPH chrome ore crushing plant in South Africa

South Africa mineral resources are very rich, it take 50% mineral resources of Africa countries in amount and the mineral resources is the fifth one of the world. Especially, the platinum metals, the chrome, gold, andalusite, vanadiumore resources are the first one of the world. South Africa is Chrome oxide and there is only one compary (the MMC) have electrolysis Chrome production line. So a large amount of Chrome ore is mainly used for export. While, the quality of South Africa Chrome ore is very good, the Chrome content by weight is about 50%. Great many South Africa Chrome ore crusher are installed here for its advantages.

Chrome Ore Crusher Plant for Sale in South Africa

At the beginning of 2011, one customer from America made one inquiry and would like to invest in building one 200TPH Chrome ore crushing plant in South Africa. Communicated with him and his partner, we have a general idea of their demands and we shared our opinion with them according to their budget.

Finally we got an agreement of one design and they placed an order after visiting Double Company and Double factory. In this Chrome ore crushing plant, one unit vibrating feeder, one unit jaw crusher and two units cone crushers and two units vibrating screen are used.

Chrome ore processing equipment

The whole crushing process begins from dumping the raw ore to steel hopper above the vibrating feeder, which ensure steady feeding process. Double vibrating feeder structure is very simple and we strengthen the wear parts, increasing the service life greatly. To the jaw crusher, we adopt heavy movable jaw and optimized connect methods, in this way, the hard mining ores can be crushed easily.

Obviously, jaw crushers are just primary crushers, they can crush big lumps to small lumps, but the products output size is still bigger than customers’ requirements. So when material discharged from the bottom of the jaw crusher, they are transported to one transfer station by belt conveyors. Under the transfer station, there are two units electric vibrating feeders, they feed the crushed lumps to belt conveyor steadily.

Then the lumps will be fed to the cone crusher. Double has two series cone crusher for sale in South Africa, one is HP series hydraulic cone crusher and another one is S series cone crusher. Here considering the budget, we suggest customer using two set S series cone crushers. By using this type cone crusher, customers can crusher mining ore aggregates to small particles easily.

For example, mining ore lumps can be crushed to 0~5mm, 5~10mm, 10~20mm or 0~1/8”, 1/8”~1/4”, 1/4”~1/2”, 1/2”~3/4” and 3/4”~1”. These size ranges well satisfy the world’s customers’ commonly requirements. Particles outputted from cone crushers are mixed with each other, to separate the different sizes particles, Double vibrating screens are necessary. The wire meshes are changeable, so producers just need to change the wire mesh if they need produce different size products. Finally, the qualified ones are conveyed to the store pile sites and oversize ones are transported to the cone crushers for crushing again.

Crusher plant production and maintenance

The production line of crusher plant mainly consists of Vibrating Feeder, Jaw Crusher, Impact Crusher, Vibrating Screen, Belt Conveyor, Electric Control Box, etc. Double equipment design different production lines ranging 50 t/h to 500 t/h by combining different models of equipments also matching Cone Crusher, Bag Dust Catcher, etc. to satisfy different customers’ technological requirements.

Crusher plant maintenance

Convenient maintenance is so important in the quarrying crusher plant industry. Maintenance can be defined as working on something to keep it in a functioning and safe state and preserving it from failure or decline. Maintenance activities at quarries range from the maintenance of machines, equipment and vehicles to the keeping of roadways on site in good order, attending to such matters as providing edge protection and securing excavations.

It’s important to keep structural costs down, to design for ease of maintenance and operation, and to combine best practices with advances in fabrication and erection.

Best installation for crusher plant

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.Since the crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation.

The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with today’s tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor.
