Chitsulo ife ntchito lero amachokera m'nyanja kuti analipo pafupifupi biliyoni zaka ziwiri zapitazo amene teaming ndi chitsulo kusungunuka. Pamene zamoyo poyamba angathe dzuwa anayamba mpweya matupi chitsulo wachuma wa madzi, chitsulo anayamba kupanga monga madipoziti pa matanthwe a Dziko Lapansi, kutanthauza kuti kwenikweni opezeka miyala nyanja.
Ores munali zedi mkulu wa magnetite (lomwe lili 72% chitsulo) ndipo hematite (lomwe lili 70% chitsulo) amadziwika ngati "chachibadwidwe" kapena "kutumiza mwachindunji" ores. zinthuzi akhoza kupita mwachindunji ng'anjo chitsulo zobweretsa yopanga zitsulo.
Komabe, kuyambira madipoziti ndi miyala amene akumira kuti mabiliyoni nyanja pansi zaka zapitazo wosanganiza ndi zinthu zina ndi mchere, chitsulo amapezeka zimene amadziwika monga formations mkombero wachitsulo. Izi zambiri ali ndende m'munsi achitsulo chosakanizika ndi silicates, oxides, ndi zina carbonates. Kuchita masamu, pulling one ton of zitsulo from banded formations creates up to three tons of tailings.
Pamene zili zowona kuti Chitsulo ndicho chinthu chachinayi ambiri opezeka padziko lathuli ndi (pambuyo mpweya, pakachitsulo, ndipo zotayidwa), matani izo kwenikweni kuti "anaponyedwa" chifukwa izo siziri kukhala bwino yotengedwa. Pakadali pano, pali sizikuwoneka kukhala kuchepa kwa chitsulo dziko. Komabe, mining does have an environmental impact. Ndipo tailings amene amayambira ndi njira yonyowa maginito ndi flotation muyenera madzi atsopano, and require the introduction of expensive and potentially toxic chemicals that must be stored until decontaminated.
cha ku Switzerland Zida & Technology ili ndi yankho labwinoko. triboelectrostatic youma wathu ndondomeko kulekana akhoza kudzapeza kuchotsa zitsulo kuchokera zinyalala mitsinje, kuchotsa kufunika gwero mwatsopano madzi, ndalama mankhwala flotation, ndi kumanga yonyowa ndondomeko tailing amatunga. No decontamination m'pofunika.
This separator is environmentally friendly because it doesn’t use a lot of energy, but it can process a high volume of material quickly to increase your output—not only iron ore, koma ina zinthu zamtengo wapatali kuti zikhale tailings wanu kuphatikizapo mkuwa, faifi tambala, ndi cobalt. Kuphatikiza apo, the separator can be used at your mining site so there’s no need or expense for shipping materials to a facility for sorting.
