Complete Ore Processing & Milling Plants: Crushing Equipment, Grinding Equipment, Fine sieving grading equipment.
Re-election and flotation process is different. Flotation in sand and gravel production line is a the monomer separation finely ground to a fine-grained mineral flotation reagent is added based on the differences in the physical and chemical properties of mineral surfaces in the pulp, will be separated from the useful minerals and gangue concentrate product.Re-election of ore crushed gravel equipment in different campaigns in the media, due to the different densities of useful minerals and gangue minerals, its separation, to achieve the purpose of concentrate product. Flotation is crushing → grinding → the floatation → concentrate treatment process, re-election is broken → phase out → Grinding → shaking → concentrate treatment process, therefore, the processing flow, plant configuration etc. are not the same. From the processing of ore beneficiation and processing, can be roughly divided into crushing (including primary crushing, broken and finely divided), grinding, sorting, the concentrate handling four program. Different according to the nature of the ore, the size of the value of useful minerals, ore beneficiation degree of difficulty can be broken down into a lot of ore processing process. For example, Sec broken, three-stage grinding, secondary primaries, three scavenger, three Featured constitute a multi-program beneficiation process. In short, in order to make full recovery of mineral resources, industrial requirements concentrates, various beneficiation process can be used, in order to achieve election other purpose.
The hematite equipment process and sorting methods: Refinery processing of ore hematite hard rock, mainly iron minerals the martite half martite, gangue minerals are quartz, followed by hornblende, chlorite, ore showed the banded structure, disseminated fine-grained illusion of hematite and quartz particle size is generally 0.02-0.2mm, ore be ground to -200 mesh 80% g / t, dubbeda 20% aqueous solution, by adding the second paragraph of the grinding machine, flotation ph value of the PH value of 8.5-9.5, slurry temperature of 30-33 degrees, the collector agent is a mixture of paraffin oxide soap 390g / t and tall oil 130g / t,re-election, mainly used for sorting the weak magnetic hematite iron ore, and its application in two ways: geological taste higher (about 50%) but more the orebody is thin or mezzaninemining when the waste-ore, ore dilution of this ore can be used only broken grinding coarse tailings discarded by the re-election, in the case of coarse grain size, thereby restoring the geological taste, coarse mediumtaste concentrate, or further processed or sent directly to the blast furnace smelting, known as coarse-grained re-election, another red fine-grained disseminated ore or mixed ore (ie with weak magnetic red ore and strong magneticmagnetite), by crushing, grinding iron mineral monomer after the separation, magnetic reconnection through re-election or election, get fine-grained high grade concentrate, known as the fine-grained hematite re-election.
