Mineral Processing ndi kulekanitsa kwa mchere womwe umayang'aniridwa ndi mchere wina wozungulira. Njirayi imagawidwa m'magawo awiri. Kutengera mchere, processing akhoza kuchitidwa m'njira zosiyanasiyana. Pa cha ku Switzerland Zida & Technology (STET), tadzipereka kuti tipeze wokonda zachilengedwe, zotsika mtengo, ndi njira yachangu yopangira ma mineral processing. Ndicho chifukwa ife analenga STET wathu olekanitsa triboelectric. Ndi chida ichi cholekanitsa mchere, pezani mankhwala apamwamba kwambiri munthawi yochepa, pamtengo wotsika.
Kukonza mchere ndi njira yochotsera mchere pansi. Kuwalekanitsa mu zigawo zothandiza ndi zosathandiza. Mwachitsanzo, ngati mukuyesera kuchotsa chitsulo pansi, mudzachotsa nawo mchere wina wambiri. Kuti mulekanitse mcherewu ndi chitsulo chomwe mukuyesera kuchotsa, ndalamazo zidzafunika kudutsa mu mineral processing. Njira imeneyi imagawidwa m’zigawo ziŵiri zazikulu—kukonzekera ndi kulekanitsa.
Pali njira ziwiri zazikulu pakukonza mchere. Gawo lirilonse lingathe kuchitidwa m'njira zingapo. Zida ndi njira zolekanitsa mchere zimasankhidwa kutengera mchere womwe mukuyang'ana kuti muchotse komanso kapangidwe kake kake.
Pofuna kulekanitsa bwino mchere wosankhidwa ndi ore, ziyenera kukonzedwa. Cholinga chokonzekera miyalayi ndikupangitsa kulekanitsa kukhala kosavuta kwa mchere wosiyanasiyana. Mchere uliwonse uyenera kuwululidwa pang'ono kapena mokwanira kuti ntchito yolekanitsa igwire ntchito. Kuwulula mchere, the ore deposits must be crushed or ground into small pieces.
Zidutswa zazikulu za miyala zimayikidwa mu chopukusira kapena chopukusira ndikusinthidwa kukhala tizidutswa tating'ono. Zidutswazi zimayikidwanso mu chopukusira kapena chopukusira mpaka kukula kwake komwe mukufunikira kuti mulekanitse kukwaniritsidwe. Ma crushers angapo ndi zopukutira zitha kugwiritsidwa ntchito kukwaniritsa kukula koyenera. Zida zopangira mchere chifukwa izi zikuphatikizapo nsagwada ndi gyratory crushers, ma cone crushers, zotsatira za crushers, mpukutu crushers, and grinding mills.
Kulekanitsa mchere ndi pamene mchere wothandiza umasiyanitsidwa ndi mchere wosathandiza (amadziwikanso kuti zida za gangue). Malingana ndi mtundu wa mchere womwe mukuyang'ana kuchotsa, mutha kugwiritsa ntchito njira zolekanitsa zosiyanasiyana, kapena kuphatikiza njira, including wet separation or dry separation.
Kulekanitsa konyowa kumaphatikizapo kugwiritsa ntchito madzi kuti alekanitse mchere. Mitundu yayikulu ya kulekanitsa konyowa ndikulekanitsa kwa flotation ndi kulekanitsa konyowa kwa maginito. Kupatukana kwa flotation kumagwiritsa ntchito mankhwala a mchere wofunidwa. Posankha chinthu china chamankhwala chomwe chimagwirizana ndi mchere, mcherewo umatsatira zomwe zimachitika-kuzilekanitsa ndi zipangizo zina. Ndi kupatukana konyowa kwa maginito, mcherewo umayang'ana kutengera ma frequency ake a maginito. M'ng'oma ndi madzi, mphamvu ya maginito yotsika kapena yamphamvu kwambiri imagwiritsidwa ntchito kulekanitsa mchere. Ndi kupatukana konyowa, mapeto ayenera zouma mwa dewatering.
Kupatukana kowuma sikugwiritsa ntchito madzi komanso kumakhala kosamalira zachilengedwe. Mitundu yayikulu ya kulekanitsa kowuma ndi kulekanitsa mphamvu yokoka, kugawanika kwa maginito owuma, ndi kulekanitsa electrostatic. Kupatukana kwa mphamvu yokoka kumagwiritsa ntchito mphamvu yokoka yosiyanasiyana pa mchere kuti igwirizane ndi mchere wosankhidwa. Kusiyanitsa kowuma kwa maginito kumagwiritsa ntchito njira yofanana ndi kulekanitsa konyowa kwa maginito koma popanda kugwiritsa ntchito madzi. Electrostatic kupatukana kumagwiritsa ntchito mtengo wa mchere kuti usiyanitse ndi ena.
Kupatukana kwa triboelectric ndi njira imodzi yabwino yolekanitsira mchere wina ndi mnzake. Mkati mwa cholekanitsa cha triboelectric, particles amalipidwa, kulekanitsidwa ndi malipiro, ndi kulekanitsidwa ndi mphamvu yokoka. Zonsezi zimachitika ndi makina amodzi. Ma mineral amasiyanitsidwa mwachangu komanso mosavuta. Zotsatira zake ndi mankhwala owuma kwambiri omwe ali okonzeka kupeta. Kuphatikiza apo, kupatukana kwa triboelectric kumalola kutsika kwa ndalama / ndalama zogwirira ntchito ndipo kumayambitsa kukhudzidwa kochepa pa chilengedwe.
Kuyang'ana yachangu, njira yosavuta yopangira mchere? Gwiritsani ntchito zida za STET za electrostatic kulekana. Timapereka zida zamakono zolekanitsa mchere kwa makasitomala athu ndikuwathandiza. Ndikufuna kuphunzira zambiri? Lumikizanani nafe lero!
