Ore processing plant is also called beneficiation plant. It is a kind of production line of selecting kinds of mineral ores.
The general process is : crush big mineral stone into small size (0-20mm) , grinding these small stone into powder (or slurry) , then separate the useful ore from the powder (slurry).
There mainly have four kinds of separation method :
(1) Flotation separation
(2) Gravity separation
(3) Leaching separation
(4) Magnetic separation
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.
The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals..
It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores".
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight.
It suitable for Alluvial gold ,lead , chromium ect.
Leaching is the process of extracting substances from a solid by dissolving them in a liquid.
The leaching of precious metals such as gold can be carried out with cyanide or ozone under mild conditions.
Leaching method suitable for Oxidized ore.
Magnetic Separation is which separating components of mixtures by using magnets to attract magnetically susceptible materials.
It suitable for iron , Manganese ore ect.
Jaw crusher is the primary crusher in stone crushing plant , it used to crush big size ore into medium size .
Cone crusher is the secondary crusher , used to crush medium size ore stone into 0-20mm .
Ball mill is the key milling equipment after material has been crushed.
It used to grinding 0-20mm ore stone into powder (dry grinding ) or slurry ( wet grinding ) , after grinding , the ore size is around 120 mesh.
Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are a partially drained fraction containing the coarse material (called the underflow) and a fine fraction along with the remaining portion of the liquid medium (called the overflow).
This flotation machine is suitable for separating non-ferrous and ferrous metals as well as non metals such as fluorite and talc.The structure of flotation machine: this machine is mainly composed of pulp chute, mixing device, air charging system, mineralized bubble discharging device and electro motor.
A Gold Shaking Table are basically low-capacity machines used as last step in the gold upgrading process.
A magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metal.
