Newer mining technologies were developed to process ore with low mineral content, and today it is common to mine ore with a purity of just .35%—only 7 pounds of metal per ton! Extraction techniques have changed from underground methods to "open pit" mining that can process larger volumes of raw material refined on site.

With the development of mining industry, investors present various requirements of the features of flotation machine. Now there are many kinds of flotation machines, such as agitator flotation machine, pneumatic flotation machine and pneumatic- agitator flotation machine. And different mineral ores have different hydrophilicity, so the final configurations greatly depend on the professional designs.
Mobile crushers are loaded on their own crawler tracks or towed by truck horse when transported over longer distances to a new location. With tremendous flexibility and compact design, customers can take this machine directly to rock crushing plants or demolition sites for powerful, handy recycling of reusable construction materials, concrete debris, sand and gravel with economic efficiency.
The Mobile Cone Crusher (plants) has excellent mobility, it can move to anywhere with the change of raw material places or the construction places and start to work without building any foundation. Also it is easy to match with other equipments, meeting the different product requirements of different customers.
By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
Vibrating Feeder is a kind of linear-direction feeding equipment, in the mineral ore &rocks processing plants, it can send materials to crusher evenly and continuously. At the same time, it can screen materials roughly, increasing the practical handling capacity of the whole production line.
