A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other. Large to medium ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion).
The cultural role of copper has been important, particularly in currency. Romans in the 6th through 3rd centuries BC used copper lumps as money. At first, the copper itself was valued, but gradually the shape and look of the copper became more important. Julius Caesar had his own coins made from brass, while Octavianus Augustus Caesar's coins were made from Cu-Pb-Sn alloys. With an estimated annual output of around 15,000t, Roman copper mining and smelting activities reached a scale unsurpassed until the time of the Industrial Revolution; the provinces most intensely mined were those of Hispania, Cyprus and in Central Europe.
The raw materials will be firstly sent into crusher machine for primary and fine crushing, and then the crushed particle sizes will be sent into ball mill for further grinding and spiral classifier for washing and grading. After this process, the materials will be sent into flotation machine or magnetic separator for ore separation to get the concentrate. The concentrator and rotary dryer are the optional.
The silicate rich product, which contained 24.24% iron, was also further separated with an air swept magnetic separator. The two products obtained from that separation included an iron oxide rich product having 61.27% iron and a silicate rich product having 18.73% iron. Finally, the metallic iron rich product generated from the further possessing of the original iron oxide rich product and which contained 78.79% iron as noted above, was screened at 65 mesh. The product that did not pass through the screen and hence, was coarser than 65 mesh, contained 87.22% iron which is a metallic iron rich product with higher iron content than the total product group prior to the screening operation. The portion of the metallic iron rich product which passed through the 65 mesh screen had an iron content of 72.42%. In the current market, the higher iron content product can sell for a higher price, thus justifying the further separation of the original metallic iron rich product. Of course, the above description is set forth in view of presently preferred embodiments and is not intended to limit the invention in any way. There can be many other variations and combinations of the separation techniques and processes disclosed herein. All such variations and combinations are intended to fall within the spirit and scope of this invention, as set forth in the following claims.

Xanthate acts as a collector that attaches to the mineral surface and produces a hydrophobic, surface. The water-repellent film thus formed facilitates the attachment of the mineral particle to an air bubble. Fuel oil improves the flotation of molybdenite.
Expansion and shrinkage of expansive soil is mainly due to water absorption of expansive mineral in soil. After absorbing water, the thickness of water film will change. The thinner the thickness, the greater the cohesive force between the particles, the higher the shear strength of the soil, and the smaller the swell-shrinking property. After added to the expansive soil and assisted by water, lime is dissociated into Ca2+ and OH− ions. Ca2+ is replaced by Na+ and K+ in the clay particles by ion exchange, so that the colloidal adsorption layer is thinned. As a result, the thickness of water film becomes thinner and the swelling potential of the soil reduces. In addition, alkaline environment accelerates ion exchange. As lime is one kind of alkali, the pH value of expansive soil increases with the addition of lime. Generally speaking, the more the lime is, the more the ion exchanged will be.
Of course, there are also sands available for septic backfill and many other purposes. Each type of sand will have its own pricing based on the processes used to manufacture the material and its availability.
Shilu iron deposit in Hainan Province was hailed as “Asia’s largest iron ore rich”, and ore mineral is mainly hematite, associated with cobalt, copper and nickel. At present, there is no unified understanding of the ore-forming mechanism of Shilu iron ore deposit. Some argued that formation of Shilu iron ore is mainly due to multiple remodeling and enrichment that is, the formation of iron ore deposits is affected by “volcano-sedimentary metamorphism + structural transformation + hydrothermal”. A total of 38 iron ore bodies have been found, most of which are yielded in the 6th layer of Shilu Group. The proven iron ore reserve has exceeded 450 million tons and the grade is high (the average grade of iron ore is 51%) [11, 14, 15].
Based on 100lbs/CuFt material, following are max capacity of grinding per batch.
Magnetic dry separator is of large processing capacity and is good at selecting and refining medium-large-granularity (<=10mm) high-intensity magnetic material, recovery of heavy magnetic medium, and removing iron from mineral.
