Kodi kugwiritsa ntchito flotation ndi chiyani?

Kuyenga miyala ndi njira yopangira zinthu zopangira zitsulo ndi makampani opanga mankhwala, ndipo kuyandama kwa thovu kwakhala njira yofunika kwambiri yoyenga. Pafupifupi zinthu zonse zamchere zimatha kulekanitsidwa pogwiritsa ntchito kuyandama.

Pakadali pano, flotation imagwiritsidwa ntchito kwambiri popanga zitsulo zachitsulo—makamaka chitsulo ndi manganese—monga hematite, smithsonite, ndi ilmenite; zitsulo zamtengo wapatali monga golide ndi siliva; zitsulo zopanda chitsulo monga mkuwa, lead, zinc, cobalt, nickel, molybdenum, ndi antimony, kuphatikizapo mchere wa sulfide monga galena, sphalerite, chalcopyrite, bornite, molybdenite, ndi pentlandite, komanso mchere wa oxide monga malachite, cerussite, hemimorphite, cassiterite, ndi wolframite. Imagwiritsidwanso ntchito pa mchere wopanda chitsulo monga fluorite, apatite, ndi barite, mchere wosungunuka monga potashi ndi mchere wa miyala, ndi mchere wopanda chitsulo ndi mchere wa silicate monga malasha, graphite, sulfure, diamondi, quartz, mica, feldspar, beryl, ndi spodumene.

Flotation yapeza luso lalikulu pantchito yopangira zinthu zatsopano, ndi kupita patsogolo kwaukadaulo kosalekeza. Miyala yomwe kale inkaonedwa kuti siili ndi phindu la mafakitale chifukwa cha kapangidwe kake kochepa kapena kovuta tsopano ikubwezedwa (ngati chuma chachiwiri) kudzera mu flotation.

Pamene mchere ukukhala wosalimba kwambiri, ndi mchere wothandiza womwe ukugawidwa bwino komanso mozama mkati mwa miyala, vuto lolekanitsa lakula. Pofuna kuchepetsa ndalama zopangira, mafakitale monga zipangizo zachitsulo ndi mankhwala akhazikitsa miyezo yapamwamba kwambiri komanso zofunikira pakukonzekera zipangizo zopangira—ndiko kuti, zinthu zolekanitsidwa.

Kumbali imodzi, pakufunika kukonza ubwino, ndipo kumbali ina, vuto lolekanitsa mchere wosalala lapangitsa kuti kuyandama kwa nthaka kukhale kwapamwamba kwambiri kuposa njira zina, zomwe zapangitsa kuti ikhale njira yopindulitsa yomwe imagwiritsidwa ntchito kwambiri komanso yodalirika masiku ano. Poyamba imagwiritsidwa ntchito pa mchere wa sulfide, kuyandama kwa nthaka kwakula pang'onopang'ono mpaka kuphatikiza mchere wa oxide ndi mchere wosakhala wachitsulo. Masiku ano, kuchuluka kwa mchere padziko lonse lapansi komwe kumakonzedwa ndi kuyandama kwa nthaka kumaposa matani mabiliyoni angapo.

M'zaka makumi angapo zapitazi, kugwiritsa ntchito ukadaulo wa flotation kwakula kuposa uinjiniya wokonza mchere kupita kumadera monga kuteteza chilengedwe, zitsulo, kupanga mapepala, ulimi, mankhwala, chakudya, zipangizo, mankhwala, ndi zamoyo.

Zitsanzo zikuphatikizapo kubweza zinthu zofunika kuchokera ku zinthu zapakati mu pyrometallurgy, volatiles, ndi slag; kubweza kwa zotsalira za leaching ndi kusamuka kwa madzi mu hydrometallurgy; kugwiritsa ntchito kubweza kwa madzi mumakampani opanga mankhwala pochotsa inki ya mapepala obwezerezedwanso ndi kubweza ulusi kuchokera ku mowa wotayidwa wa pulp; ndi ntchito zaukadaulo zachilengedwe monga kuchotsa mafuta olemera kuchokera ku zinyalala za m'mphepete mwa mitsinje, kulekanitsa zonyansa zazing'ono kuchokera ku madzi otayidwa, ndikuchotsa ma colloids, mabakiteriya, ndi zinyalala zachitsulo.

Ndi kusintha kwa njira zoyendetsera madzi ndi njira zoyendetsera madzi, komanso kutulukira kwa zida zatsopano komanso zogwira mtima kwambiri zoyendetsera madzi ndi zida, kuyendetsa madzi ndi zinthu zina kudzagwiritsidwa ntchito kwambiri m'mafakitale ndi m'magawo ambiri. Komabe, ndikofunikira kudziwa kuti kugwiritsa ntchito kuyendetsa madzi ndi zinthu zina kumaphatikizapo ndalama zambiri zoyendetsera madzi (poyerekeza ndi kulekanitsa kwa maginito kapena mphamvu yokoka), zofunikira kwambiri pakukula kwa tinthu ta chakudya, zinthu zambiri zomwe zimakhudza njira yoyendetsera madzi ndi zinthu zina zomwe zimafuna kulondola kwakukulu, komanso zoopsa zomwe zingachitike chifukwa cha madzi otayira omwe ali ndi zinthu zotsalira.

Lumikizanani nafe tsopano!
