Diamond, also means mineralogy diamond,it is formed by geological processes.The primary ore mainly are kimberlite and lamproite. Modern science and technology provide new ideas and methodsfor diamond exploitation and diamond formation. As we all know, diamond is the hardest gem in the world, it has thesimplest ingredients, which is composed of carbon, and a natural cubic crystal structure. Its composition is same ascoal, pencil and sugars that are closely related to us. Under the pressure (high temperatures), carbon will crystallize to form graphite (black), while under high pressures and high temperature, carbon will crystallize to form precious diamonds (white). So diamonds are very precious, and so it has very high value, and lots of people want to own them in Russia, so diamond exploitation is very important for the investors who want to gain many profits from diamond industry.
Diamond is a natural mineral that is rough diamonds. It is understood that the diamond native deposits, mostly adopt the method of combination between the open-pit mining and underground mining. On the part of earth’s surface, directly along the rock excavate the pit barrel, and stepped down mining drill, each step will spiral downward which is easy for truck to transport the ore out. On the other hand, when deep underground (300 meters), the first thing is to dig a well next the mineral deposit, then dig a lateral tunnel leading to the deposit, then through technical means to make internal ore be crushed, and then through a series of horizontal and vertical roadway to transport the ore out.
As for the diamond sand deposits, which can be divided into two categories: one is the ancient beach, the ancient river diamond deposits exposed above the water, it can removethe overlying sediment, then using the method of open pit mining, then sent the gravel to the concentrator, while the other deposit is located at the bottom of the modern river, known as the "wet deposit", you need to first drain the water or diverse the river, and then adopt the method of open-pit mining.
It is reported that the ore after mined first should use jaw crusher and cone crusher for crushing, sometimes also put the ore in open pit mine, and then natural weathering crushing. After the ore were crushed to 3 to 6cm,and then will remove the clay with roller washing machine.Then you can use the bouncing beneficiation method to separate coarse gravel after washing, as to the separated coarse gravel, you can have second crushing and panning separation. Or use gravity beneficiation methods, because diamond ore density is larger than other ores, so the ore contains diamonds will be discharged from the bottom of the funnel-shaped container.
After above these coarse dressing, if diamonds still cannot be completely separated, then should have further selection. In fact we can use the diamond lipophilic water-repellent properties, the ore which containing diamonds will be scattered evenly on the tapewith grease and kept turning, so make the surface of grease tostick the diamond.Then, the oil will be collected in a container which is made of fine metal sieve cloth, then put in the hot water pool, let the oil melting and then drift away. After roughing and fine selection, then manually recycle diamondby the professional technical personnel.
