Application of Cone Crusher in Copper Processing

Spring cone crusher is one of the important machine in the mineral processing equipment, spring cone break a major role in the mineral processing equipment containing  copper ore crushing and then into the ball mill grinding to a certain degree of fineness. The main selection copper process: crushing - milling - classification - flotation- Selected, with nickel-cobalt-molybdenum gold and other rare metal ore can be rougher copper concentrate were flotation of nickel concentrate, cobalt concentrate, molybdenum concentrate, gold concentrate.
Since copper is selected, first of all we need to know some knowledge of the copper; the copper ore is generally of copper oxide or sulfide to generate blue-green copper sulfate and sulfuric acid reaction. Natural copper copper a variety of colors. Bornite dark copperred, oxidized into a blue-violet porphyritic; chalcocite (sulfide copper) lead gray;ceruloplasmin (copper sulfide) indigo; tetrahedrite steel gray; azurite (called Zeng Qingor azurite) was bright blue.
The copper minerals raw materials in China have the following characteristics: 1. For smelt production of raw materials of the copper minerals, hosted in a variety of deposit types. Among them, an important mining the value of deposit types: magmatic copper-nickel sulfide deposits, porphyry copper deposits, skarn copper and polymetallicdeposits, hydrothermal vein-type copper deposits, volcanic - sedimentary massive sulfide copper deposits, sedimentary layered deposits. Ore texture and structure complex, embedded uneven particle size distribution, particle size of ore uneven dip, even a lot of mineral assemblages, fabrics disseminated subtle, complex composition of refractory or more. Diverse chemical composition of ore associated symbiotic variety ofbeneficial and harmful components, the complexity of the dressing and smelting processconditions. Currently, the majority of the development of mining integrated copper deposits, associated to a variety of beneficial to harmful elements. Comprehensive mining and utilization, variable damage to the interests of turning waste into treasure.

Application of Buffer Blasting in Dressing Plant

Cushion blasting in the concentrator is often applied to a method of blasting and cushion blasting stone, can be a good application with spring cone crusher again broken, let's look at the specific introduction of the cushion blasting:
Close to the slope of the buffer blasting along close to the slope boundary arrangement of several rows of the resistance line and charge weight are gradually decreasing thebuffer holes to form a buffer layer capable of attenuating the seismic effect, and after thebursting of the normal mining initiation. It is the easiest method of controlled blasting.
Cushion blasting a more general order of blasting vibration reduction about 20%.Cushion blasting is ideal for the protection of the loose rock slope. In order to more effectively protect the slope, cushion blasting is often used in conjunction with the pre-split blasting or smooth blasting. And pre-splitting blasting used in conjunction with the cushion blasting is in the pre-hole blasting, mining district before the main burst holeblasting initiation; if used in conjunction with the smooth blasting after blasting in themining district burst Kong faces light blasting prior to initiation.
The main advantage of the cushion blasting: Jane cheaper line; than the pre-split the value of smooth blasting, drilling, large diameter, while the larger aperture accurate layout of the drilling and easy to drill deeper holes. Its disadvantages: if used in conjunction with the pre-splitting blasting or smooth blasting can not be used for urgent changes insection; the mining district, blasting the backlash may sometimes be partial or total disruption buffer blasting platform.

The Beneficiation Technology of Manganese Ore

Manganese ore beneficiation process knowledge:
(A) the oxidation of manganese ore. Secondary deposits to weathering, oxidation of manganese ore mainly native of sedimentary and hydrothermal deposits and supergene oxide manganese ore. Ore, manganese mineral hollandite, pyrolusite, and manganite; gangue silicate minerals, carbonate minerals; often accompanied by pig iron, phosphorus, nickel, cobalt and other ingredients.
The oxidation of manganese ore beneficiation in order to re-election. Weathered oxide ore often contains a lot of slime and fine ore, the production of washing - re-election method. Ore the Jingxi ore remove the slime net proceeds of mines, and some can be used as the processed ore, some need to use a jig and shaking re-election. Washing overflow sometimes also need to further re-election or high intensity magnetic separation methods such as recycling. Some deposition native oxide manganese ore, mining dilution, used in the production of heavy medium and jig re-election to remove gangue, massive concentrate.
Iron oxide manganese ore, iron minerals limonite. Iron and manganese with difficult re-election, flotation or strong magnetic separation, reduction roasting. Industrial washing - to restore the roasting process - re-election.
(II) carbonate manganese ore. Sedimentary carbonate manganese ore, the main manganese mineral rhodochrosite, calcium rhodochrosite, manganese, calcite and siderite and manganese ore; gangue silicate and carbonate minerals; also often accompanied by sulphide and iron impurities. Is generally more complex ore, manganese mineral disseminated fine grain size to microns, less dissociation is often difficult to get a higher concentrate grade.
Manganese carbonate ore beneficiation production practice less, and high intensity magnetic separation, heavy media beneficiation and flotation methods. Some sedimentary sulfur carbonate manganese ore, industrial, carbonaceous shale, pyrite, and the order of the manganese mineral flotation processes. Some hydrothermal lead, zinc carbonate manganese ore, flotation - high intensity magnetic separation process. Some sulfur-rich manganese ore, manganese mineral sulfur manganese, roasting methods can be used in addition to sulfur. Some rich carbonate manganese ore production, roasting methods, to remove volatile components and the finished ore.

Three Methods of Mining Tailings Utilization

Our technical staff said the three the most simple and feasible method of tailings management and utilization as follows:
The first is the use of the tailings to the development of building materials. Gold tailings, silica sand, sandstone, or quartz can be used. Brick is the most common building materials, tailings brick-making is also a good method of adding a certain amount of lime made of brick, and then into the carbonization chamber, which leads toCO2 carbonation into the brick will not only increase the pressure of the brick to reduce the earth destroyed, the considerable economic benefits. Tailings can also manufacture flat glass and a variety of insulation, thermal insulation, and sound insulation materials. In addition, to extract valuable metals from the tailings technology has been utilized.
The second is the use of organic waste, to take biodegradable curing of gold mine tailings dust, closed, select the appropriate seed and matrix so that the plants rapidly germinate, grow in order to achieve the purpose of vegetation use. This treatment of tailings through years of practice, and explore some experience, especially in the degradation of solidified waste selection matrix, seed selection and germination time to do a number of experiments, some have been successful. It overcomes the intensive soil, tailings shape of the drawbacks of limited governance inconvenience.
Third casing farmland. Pressure of 10-20 cm of soil in a more adequate soil areas can be used then to plant, overburden farmland, expansion of arable land, this method is applicable to the tail inks showed an inverse hump-shaped. Over the years, this approach has been affirmed. But the soil is thin due to the pressure, secondary hazards caused by dust.

Common Problems in Crushing Equipment Management

Not timely renewal of equipment, machinery and equipment lags behind cannot meet the production needs of the development
Under market economy conditions, the distribution according to work policy implemented, the enthusiasm of enterprises for their production and a substantial increase, the production targets are also growing, due to lack of enterprise funds, the management of personnel management lags behind for various reasons, resulting in an update of the technical equipment updating unsatisfactory. Mainly: high energy consumption equipment, low efficiency, high downtime maintenance of high maintenance costs. Aging backward level of machinery and equipment to become enterprises to improve production, reduce the cost of the main constraints.
Equipment, routine maintenance work the lack of
 Device point test repair system did not perform or the implementation of strict. Many mining enterprises point test equipment repair system does not attach importance to the traditional plan or pre-repair system, leading to many equipment had to repair or owed to repair serious impact on the technical status of the equipment, increase maintenance costs.
Cleaning of equipment lubrication, the impact of vulnerability periodic replacement and other maintenance work is imperfect, some venues such as the stope mining enterprise in which the environment is not good, underground dust, noise, vibration, wear parts, equipment, working environment is wet and other factors, the routine maintenance of mining machinery and electrical equipment maintenance requirements than in other industries. But most of the mining enterprises, equipment management focus during the maintenance, neglect of cleaning equipment lubrication, leading to Mount Sassafras resistance, loss of equipment to speed up, shorten equipment maintenance period.
Storage equipment technical condition is not intact. Some mining enterprises archive device neither to take conservation measures such as dust, rust, moisture, nor also supervised and regularly checked, lack of spare parts also removed from the archive device, and verify the impact of the technical state of the archive device is sealed equipment technology situation more under daily.

Transportation and Treatment of Flotation Tailings

The concentrator tailings are often great, especially the large amount of tailing processing non-ferrous metals and depleted ore. Such a large amount of tailings is not properly handled, is bound to cause real harm and environmental pollution. Flotation planttailings discharged, the more harmful pharmaceutical river pollution harm, in order toeliminate the nuisance must be to properly handle.
In addition, the concept of the tailings is relative, tailings often contain some useful ingredients containing composition of higher-value mineral processing technology cannot be recycled tailings or not to deal with the tailings, it should be reasonable stacking and proper storage, to strengthen management to prevent loss, irreparable damage.
With the development of the technical level, to a certain period, these tailings may become valuable mineral resources.
Tailings storage dam, the valley in the Taniguchi barrier dam closure, and then inside storage of mine tailings can be. Of course, the ground enclosed tailings dam, which is mainly the concentrator commonly accumulation away from the mountains around the city. Dry tailings for dry separation plants discharge, if there is no need to recycle the useful minerals, can be used as building bricks, manufacturing of cement and other raw materials, filling of the mine tailings waste pits.
The discharge of tailings from the beneficiation contains a lot of water to the slurry-like discharge. Dry separation plant tailings discharged granular dry tailings.
Dry tailings transport: skip or tramcar, belt conveyor, aerial ropeway, car or train.
Pulp-like tailings slurry pipeline gravity discharge or sand pump, water isolation pump, row sent to the tailings dam.
