Country Application
Brazil is located in southeastern South America. Brazil is rich in mineral resources, with the features of variety, large reserves, high grade, etc.And Brazil has advanced production and development technologies. So it can meet the needs of the domestic national product, at the same time, a large number of mining products can export to other countries. Brazil has becomeone of the large mineral resources and products exporting countries of the world.Simultaneously, Brazilianmining industry has become an important growth point of national economic development. Among them, Brazilian nickel reserves are very rich. There were about 8.3 million tons of nickel ore reserves have proven in Brazil, mainly distributed in Para Sate and GoiasState. In recent years, Brazil's nickel ore and nickel production showed overall growth trend. In 2011, 11.33 million tons of nickel oreswere mined in Brazil, of which nickel production reached 110,960 tons.
Nickel is a kind of silvery-white metal.Because it has good mechanical strength and ductility, high temperature refractory and high chemical stability, and other features, it is a very important non-ferrous metals raw material. Nickelis used to manufacture stainless steel, high nickel alloy and alloy steel. And it is widely used in aircraft, radar, missiles, tanks, ships, spacecraft, nuclear reactors and other military industry. In the civilian industry, it is often used to makenickel steel, acid-resistant steel, heat-resistant steel. It can be used extensively for a variety of mechanical manufacturing. Nickel can be made of ceramic pigments and anticorrosive coating. In the chemical industry, the nickel is used as hydrogenation catalyst.
In short, due to itsexcellent performance, nickel has become an essential metal of modern aviation industry and defense industry.
Because of the features of large reserves and high grade, Brazilian nickel mining industry develops every rapidly.But how to process nickel ore?
In the nickel ore processing line, we always need jaw crusher, cone crusher, vibrating screen and some beneficiation equipment. First, large nickel ores need to be sent to jaw crusher evenly for primary crushing by vibrating screen. And then, the crushed nickel ores need to be transported to cone crusher for medium and fine crushing. Then, vibrating screen is used to separate the crushed ores into different sizes. The nickel particles which meet the requirement will be sent to beneficiation equipment. While the ores don’t reach the required size will be returned to cone crusher for re-crushing.
Nickel ores can mainly divided into copper-nickel sulfide ore and nickel oxide ore. The ore beneficiation and processing methods of them are completely different. The beneficiation methodof copper-nickel sulfide ore isflotation, and magnetic separation and gravityseparation are usually auxiliary dressing methods. The beneficiation method of nickel oxide oreis as following. We need crushing, screening and other processes to remove the large bedrockwith low degree of nickel in advance. Since the nickel element of nickel oxide is often dispersed in the gangue minerals, and the particle size is very small, and therefore nickel oxide can’t be enriched by mechanical processing method. We alwayssmelt it directly.
Customers should choose the right processing method according to the nickel mineral type. If you have any question, please contact with us, our experienced engineers will give you the best and the most professional suggestion. They can also design an efficient nickel processing line for you according to customers’ requirement. And all of the machines which used in the Brazil nickel mining plant we can provide. Both of our products and service will make you feel satisfied. We look forward to cooperating with you.
