Ruda gvožđa je četvrti najčešći element u Zemljinoj kori i generalno se izdvaja putem rudarskih operacija na otvorenom. Recovering high-grade iron ore is a relatively simple process where the mined materials are crushed and run through a magnetic separator. Međutim, gvozdene rude is often found in banded formations, surrounded by silica, Kvarca, and other contaminants. In order to recover the lower-grade iron ore, flotation separation is generally performed to maximize the yield from all mined materials. Međutim, flotation separation requires a fresh water source and chemical additives—a process that produces a high volume of toxic tailing materials that needs to be stabilized over time in holding ponds.
As valuable as lower-grade iron ore is, the wet flotation process presents three major problems for mining operators:
– Water: Unless there is a fresh water source near where mining operations are happening, water will need to be shipped in.
– Chemicals: The chemicals used in the wet flotation process add an extra expense.
– Material Management: Once the water has been treated with wet flotation chemicals, it cannot be recycled and it becomes an environmental hazard. Building holding ponds adds additional expense to a project, it takes up a significant amount of real estate, and if the toxic materials are not managed properly can create an environmental nightmare that can damage surrounding water tables and poison animals and humans. This can also lead to major lawsuits.
ST opreme & Technology has created a proprietary dry separation process that provides a far better alternative. In addition to eliminating the expenses of a fresh water source and wet flotation chemicals, naš vlasnički tribo-elektrostatički separator pojasa uzima faktor rizika po životnu sredinu iz rudarske jednačine, često olakšava dobijanje dozvola za rudarenje. Takođe može da razdvoji materijale za hranjenje na veoma fine veličine čestica, uvećavanje količine rude gvožđa koja se oporavlja od materijala za ishranu, i to je proces visokog obima koji zahteva veoma malo energije za pokretanje.
Sa manjim investicionim troškovima, smanjeni operativni troškovi, ekološki prihvatljiv sistem, i mogućnost da izvučete više rude gvožđa iz vašeg otpadnog toka, moglo bi se reći da je ST Oprema & Tehnologija ima "ironclad" proces za povećanje vašeg profita i imidža kompanije.
