Monga kudandaula komwe kumakhudza kusintha kwa nyengo kukuwonjezeka, environmentally friendly methods in the mining and mineral processing industries have become a major source of interest.
Zatsopano pakupanga mchere wouma zikubwezeretsa mwachangu njira zonyowa, ndi ST Equipment & Technology, a leader in electrostatic kulekana ndiye mutu wa paketi ndi luso lake lodula.
Ore ndi tanthawuzo lachitsulo chobadwira kapena chitsulo chonyamula kapena chitsulo chomwe chimayikidwa phindu. Kukonza mchere ndi gawo loyamba la miyala ikachoka mgodi. Njirayi imaphatikizapo kukonzekera miyala, mphero, ndi kuvala miyala, imadziwika kuti kupindula.
Phindu limasiyanitsa mbewu zamchere ndi gangue (otsika mtengo) michere yomwe imawazungulira kuti apange mchere wofunikira.
Kupatukana kumeneku kumatha kuchitika mwakuthupi, kudzera kupatukana kwa mphamvu yokoka, electrostatic kulekana, and magnetic separation, kapena mankhwala, pogwiritsa ntchito chisanu, kuthamangitsa, ndi magetsi. Mchere wosagwiritsidwa ntchito, zomwe nthawi zambiri zimatayidwa m'madamu, amatchedwa tailing.
Pofuna kumvetsetsa zabwino zakukonza mchere wouma, muyenera kumvetsetsa momwe zimasiyanirana ndi njira zina.
froth flotation kuyambira chakumapeto kwa zaka za zana la 19 ndipo inali njira yoyamba yopangidwa ndi mafakitale amigodi kusiyanitsa mchere ndi miyala.
Kusuntha kwa Froth, yomwe imagwiritsidwanso ntchito m'mafakitale obwezeretsanso mapepala ndi makina osungira madzi onyansa, imagwira ntchito pamalingaliro a kachulukidwe komanso madzi amchere amchere. Kulekana kumachitika pamene mcherewo waviikidwa mu mankhwala, kuchititsa kuti zinthuzo ziziphatikizana kutengera ngati ndi hydrophobic (wotulutsa madzi) kapena hydrophilic (kukopa madzi).
Froth flotation imagwiritsa ntchito madzi ambiri okhala ndi mankhwala, zambiri zomwe sizingatheke. Ikakonzedwa iyenera kuyanika isanafike. Izi zikutanthauza kuti si njira yabwino kwambiri yachilengedwe.
Beneficiation youma Imasiyanitsa nkhani zamchere potengera kusiyanasiyana kwake, mawonekedwe, kukula, chonyezimira, mawonekedwe, zovuta zamagetsi ndi / kapena maginito. Maginito ndi electrostatic / tribo-electrostatic kupatukana agwera m'gululi. Monga dzinalo likutanthauza, imagwiritsa ntchito zochepa, ngati madzi aliwonse kuposa momwe chimakhalira, kuchepetsa zovuta zambiri zakupera konyowa.
Electrodynamic ndi Electrostatic – are the main types of olekanitsa electrostatic. These work in a similar manner, but differ in which forces are applied to particles, i.e., kukopa kwamagetsi kapena ukulu. Kulekanitsa mphamvu yokoka kumagwiritsa ntchito mphamvu za centrifugal zosinthidwa ndi mphamvu yokoka ya ores ndi gangue kuti iwalekanitse.
Kupatukana kwa maginito kumagwira ntchito posuntha tinthu tating'onoting'ono m'maginito kuti tisiyanitse gangue ndi miyala yomwe ingagwiritsidwe ntchito.
Ubwino wopindula mopepuka umaphatikizapo zokolola zambiri ndi chitetezo, kukhazikika, ndi zero zonyansa. Kuphatikiza pakuchepetsa kugwiritsa ntchito madzi, this method has fewer production phases and uses less power and equipment.
Kuchotsa madzi kumathandizanso kuti pakhale madzi okwera mtengo, kuphatikizapo kupopera, kusanthula, kusefa, ndi centrifuging.
Ili ku Needham, Massachusetts, tapanga chopatula cha triboelectric chomwe chimasiyanitsa mchere malinga ndi momwe amatha kuchitira tribocharging, i.e., momwe tinthu timayankhira tikamagwiritsa ntchito magetsi mukamakhudzana ndimagetsi. Not only is it revolutionizing minerals processing, it’s also proven to be highly effective for chakudya & feed separation. When used to beneficiate flours, chakudya, mapuloteni maganizo, ndi ulusi.
Zida zabwino kwambiri zopatukana m'makampani, osayang'ananso kuposa Zida za ST & Technology LLC (STET). It is leading the way in the minerals separation industry. wathu triboelectric separation beneficiates micron-size particles through a totally dry process. It requires no additional materials or drying time and reduces the carbon footprint.
Kuphatikiza apo, timagwira ntchito ngati chinthu chofunikira kwa ena m'makampani opanga mchere. Contact akatswiri athu aukadaulo kuti aphunzire zambiri.
