Miyala yambiri imakhala ndi zitsulo kapena mchere. Sikuti onse ali ndi chidwi chokwanira kuti adzilungamitsira migodi. Zomwe zili ndi zinthu zamtengo wapatali zamalonda ndizomwe zimasankhidwa kuti zigwiritsidwe ntchito mu mineral processing.
Kukonza mchere kumapita ndi mayina ambiri. Nthawi zina amatchedwa beficiation, mineral dressing, kuvala ore, kuchotsa mchere, kupindula kwa mineral, kapena mineral engineering. Mawu onsewa atha kugwiritsidwa ntchito mosinthana koma akutanthauza njira yolekanitsa mchere wogwiritsidwa ntchito ndi mchere wamtengo wapatali womwe umapezeka mu ore wotchedwa gangue..
Beneficiation amagwera m'magulu awiri, chonyowa ndi chouma. Kupindula konyowa, kapena chonyowa akupera, kutengera kuchuluka kwa mchere, amaphatikiza ndi froth flotation kuchepetsa kukula kwa tinthu ndikulekanitsa mchere. Mwanjira ina, mcherewo amawaviikidwa mu njira yomwe imawalekanitsa potengera kusungunuka kwawo kwa madzi. Dry beneficiation imachokera kuzinthu zina zakuthupi zomwe zimaphatikizapo kukula kwa mchere, mawonekedwe, kachulukidwe, kapena maginito susceptibility. Ukadaulo wolekanitsa wowuma umagwiritsa ntchito madzi pang'ono ngati madzi aliwonse pokonza ndipo ndi gawo lomwe likukulirakulira chifukwa chake ubwino pochepetsa kuchuluka kwa mpweya wathu.
Chifukwa palibe kukula komwe kumakwanira njira zonse zolekanitsira mchere, pali mitundu yosiyanasiyana yaukadaulo wolekanitsa mchere. Makampani opanga zida zaukadaulo wolekanitsa akupitilizabe kupanga njira zosiyanitsira mineral. Mtengo wa Steqtech, kampani yolekanitsa mchere ku Needham, MA, ndi mtsogoleri pamakampani awa. Tinapanga a triboelectrostatic lamba olekanitsa pogwiritsa ntchito njira yowuma yopindula yomwe imakhala yothandiza komanso yothandiza pazachilengedwe.
Chinthu choyamba ndikuzindikira kusiyana kwa miyalayo kotero kuti mikhalidweyo ingagwiritsidwe ntchito kulekanitsa mchere ndi miyala yomwe ili nayo.. Izi zimatheka mwa kuphwanya ndi / kapena kugaya (comminution) mpaka mcherewo utawonekera kwathunthu, kapena “womasulidwa.”
Mu mineral processing, comminution imagwiritsa ntchito mphamvu zambiri, ngakhale poyamba zinali zogwira ntchito kwambiri. Zaka mazana angapo zapitazo, ming'oma yaing'ono ndi matope ogwiritsidwa ntchito ndi manja ankagwiritsidwa ntchito pophwanya, ndi mphero, oyendetsedwa ndi amuna, akavalo, kapena madzi ankagwiritsidwa ntchito popera. Masiku ano makina ophwanyira ndi mphero athandiza kwambiri ntchitoyi.
Chifukwa cha kusiyana kwakukulu pakati pa mchere, iwo akhoza kuyankha mosiyana ndi comminution. Mwachitsanzo, mchere wina ukhoza kukhala wofewa kapena kukhala ndi njere zazikulu kapena zazing'ono kuposa zina, kupangitsa kuti chisweke mosavuta.
Kuphwanya ndi kupera nthawi zambiri kumagwira ntchito limodzi ndi kukula, zomwe zimagawanitsa mchere molingana ndi kukula kwake. Njira yosavuta yowerengera ndikuwunika, zomwe zimadutsa tinthu tating'ono pawindo.
Kuthira madzi ndi gawo lina lofunikira la mineral processing siteji lomwe limachotsa madzi aliwonse omwe amatengedwa ndi mchere. Njira zochotsera madzi zimaphatikizapo zowonetsera, kusefa, ndi kuyanika kwamafuta. Pambuyo m'zigawo, madzi amayeretsedwa, kenako amazunguliridwanso kuti agwiritsidwe ntchito m'mafakitale.
Mitundu yosiyanasiyana ya mineral ndiyo maziko olekanitsa bwino, zomwe zimayika zinthu zamtengo wapatali. Kukonza kumawalekanitsanso ndi gangue, zomwe kenako zimatayidwa. Kupatukana katundu kumaphatikizapo physicochemical (kupatukana kwa flotation), kachulukidwe (kulekanitsa mphamvu yokoka), ndi maginito kapena magetsi (maginito ndi electrostatic kulekana).
Tekinoloje ya Electrostatic Separation (amagwiritsidwa ntchito pa ST Equipment & Technology) zikuphatikizapo triboelectric kulekanitsidwa, zomwe kuwonjezera pa kukhala bwino kwa chilengedwe, amathanso kuzindikira mchenga wamchere wonyezimira kuposa njira zina. cha ku Switzerland Zida & Lamba wolekanitsa waukadaulo waukadaulo umalekanitsa mchere kutengera momwe tinthu tating'onoting'ono timayankhira tikayikidwa m'munda wamagetsi..
anakhazikitsidwa mu 1989, cha ku Switzerland Zida & Technology LLC (STET) ndiwothandiza kwambiri pamakampani olekanitsa ma mineral omwe ali ku Needham, MA. Timapanga ndikugulitsa mchere wouma zida zopangira ntchito Beneficiation wa zabwino tinthu zipangizo. Izi zikuphatikiza eni ake, yaying'ono triboelectrostatic lamba olekanitsa ndizosavuta kuloleza ndipo zimatha kupindula ndi zinthu m'mafakitale angapo.
Tinthu tating'onoting'ono tating'onoting'ono timapindula ndi njira yowuma, popanda zida zowonjezera kapena nthawi yowumitsa. Tikufuna kugawana zambiri pazomwe timapereka, choncho chonde kukhudzana ife!
