Post subject: Focusing speak reselection method of knowledge
Posted: Today, 13:57
beneficiation process flotation process, magnetic separation process we are very familiar with, for re-election process is also a lot of people know, but it should not be familiar with the first two beneficiation process Sand Making Machine. It has a unique technology and rich experience, and has a high-tech, high-quality, high efficiency, installed by force. Production of processing equipment have been praised all walks of life. That give us today to talk about the knowledge about the re-election law.
re-election mainly adapted to process between useful minerals and gangue having a larger density difference ore or other materials. It is an effective method of grain (252 mm) and the fine ore processing coarse (greater than 25 mm). When dealing with fine slime is not efficient, modern flow membrane processing equipment can effectively recover grain size to 20-30 microns, centrifugal concentrator can go to 10 microns. Re-election beneficiation process is tungsten, tin, gold ore, in particular those dealing gold, the traditional method of sand tin. In the process of containing rare metal placers applications are very common. Re-election is also used to sorting weak magnetic iron ore Sand Making Machine, manganese ore, chrome ore. Gravity separation of iron ore, the main magnetic iron ore used for sorting, and its application, there are two:
a higher deposit geological grade (about 50%), but thinner or mezzanine ore more, When mixed with waste rock mining, the ore depleted of this mineral can be used not only broken grinding, in the case of coarse-grained and coarse-grained tailings discarded by the re-election, thereby restoring the geological grade. Obtain coarse medium grade concentrates, or further processing, or sent directly to the blast furnace, which is called coarse reselection.
The other is a fine-grained disseminated ore red or mixed mineral (ie red ore containing weakly magnetic and ferromagnetic magnetite), crushing, grinding so that after the separation of iron minerals monomer, by weight election or magnetic reconnection election, get fine high-grade ore, fines, called re-election.
