Potassium feldspar ore dressing process:
Domestic K-feldspar is rich in resources, but excessive iron content, K-feldspar in addition to iron is purified. Iron is the magnetic objects, while feldspar non-magnetic material in a magnetic field, the two are very easily separated.
The potassium feldspar raw single-handedly selected a broken one grinding a finished grading a dehydration process applies to low iron content, good quality raw material. Pre-crusher for coarse crushing and fine crushing in order to prevent the contamination of the processing of iron K-feldspar, so choose grinding equipment easy turbines, pebble mill or porcelain ball mill, ultrafine laminated since the mill etc. as grinding equipment, spiral classifier ensure product granularity.
The advantages of potassium feldspar ore dressing process:
Simple process,less investment, the disadvantage of this potassium feldspar ore dressing process is that the the product iron content indicators difficult to meet the requirements of high-quality ceramic products. In order to overcome the shortcomings of the potassium feldspar ore dressing process, increasing the magnetic separation process, proved choose wet high gradient magnetic separator effect in addition to iron,iron removal efficiency of 70% -90%.

Copper-nickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and gravity separation process are usually secondary dressing method. Flotation copper sulfide nickel ore, often used in the flotation of copper sulphide minerals collector and frother. A basic principle for determining the flotation process, would prefer to make the copper into the nickel concentrate, as much as possible to avoid nickel into copper concentrate. Copper-nickel ore flotation process has the following four basic processes.
Direct flotation or flotation process: This process can be used when the the ore copper than nickel content is much higher, election copper into separate concentrates. The advantage of this process is the low nickel containing the copper concentrate can be directly obtained.
(1)Mixed flotation process: for sorting copper below the nickel ore,the mixed concentrate directly resulting copper-nickel smelting of high nickel matte.
(2)Mixed - preferred flotation process: bulk flotation of copper-nickel ore, copper concentrate containing low nickel and copper nickel concentrate is elected separately from the mixed concentrate.

Hematite is weak magnetic. It contains mainly Fe2O3, concluding Fe70 %, O 30%, which is the major iron ore. Based on the test report of ore provided by customer, we designed this hematite beneficiation process: three stages crushing----one stage milling----two stages magnetic separation---- dehydration----final product. Using this technics, we can improve the Fe content from 40% up to 65%. And the ferric oxides recovery ratio is about 80%.
Hematite beneficiation process
1.Hematite ore crushing: in this stage there are also three steps, the hematite ore may go through primary crushing, secondary crushing and fine crushing. Hematite primary crushing equipment includes gyratory crusher, jaw crusher , hammer crusher etc. Hematite secondary and fine crushing plants mainly include cone crusher, ball mill, vertical mill, ultrafine mill etc.
2.Main operation steps in the whole hematite beneficiation process include sorting, gravity separation, floatation, magnetic separation, electrostatic separation, chemical mineral processingetc. There are many plants involves in hematite beneficiation process, such as flotation equipment, magnetic separator, electrostatic separator etc.
3.The treatments of refined hematite mineral include dehydration, tailing disposal, backwater etc. Thickener and dryer are important plants in this stage.

Iron ore beneficiation process flow:
Iron ore dressing equipment in iron ore dressing production line have their respective functions and duties. This series of equipment is mainly aimed at combining the weak magnetic separation and gravity separation, flotation, high intensity magnetic separation of hematite ore, i.e. recovering magnetite by weak magnetic spin, recovering weak magnetic iron minerals by flotation, magnetic separation,parallel process of berkelium burn magnetic separation method with other methods is similar to the magnetizing and berkelium burn of a single weak magnetic iron ore,but in parallel process of magnetized berkelium burn magnetic separation and other mineral processing methods, ore powder adopts the combination of weak magnetic separation and other methods, the selective flocculation desliming process.
Iron ore beneficiation process flow:
The iron ore is preliminarily crushed by jaw crusher,after crushing to a reasonable size through lifting machine, feeder evenly into the ball mill for crushing, grinding. After the grinding of ball mill the fine ore material is expected to enter the next process: classification.
Spiral classifier takes advantage of the principle that solid particles of different proportion in the liquid have different precipitation rates to wash and grade the ore mixture. Mineral mixture After washing and grading via the magnetic separator,due to different magnetization coefficient of various minerals, the magnetic force and mechanical force separate the magnetic material from the mixture.
After the initial separation by the magnetic separator mineral particles are fed to the flotation machine, adding different drugs according to different material characters makes the minerals separated with other substances. In the minerals separated out, because it contains large amounts of moisture, it subjects to initial concentration of the thickener, then after drying of the dryer,dry minerals is gained.

Lead and zinc used collector:
1.Xanthate such agents include the xanthate, xanthate ester, etc.
2.Sulfur nitrogen,such as diethyldithiocarbamate, its collecting capacity than xanthate.It galena,chalcopyrite collecting capacity, collecting capacity school weak pyrite selective flotation faster, uses less than xanthate. Sulfide ore coarse raw body stronger collectors than lead zinc ore processing used to be able to get better than xanthate separation efficiency, copper and lead sulfide ore sorting.
