Bauxite jẹ apata idalẹti ti o jẹ ọlọrọ ni alumina, ipilẹ fun ṣiṣe aluminiomu. It is generally easy to mine because it is found near the surface of the terrain. sibẹsibẹ, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Fun bauxite refining ilana Bayer-ti o ya alumina ti o niyelori lati awọn ohun elo ti o wa pẹlu awọn ohun elo caustic, awọn iwọn otutu giga, ati titẹ. Abajade ṣiṣan egbin, paapaa lati bauxite, jẹ slurry gbogbogbo ti a mọ ni “pẹtẹ pupa,”Iyẹn gbọdọ wa ni idaduro ni awọn adagun didimu titi ti eefin ti ojutu yoo fi di didoju. Pẹtẹpẹtẹ pupa le ni ipa ayika ti o lagbara ti awọn adagun didimu ba kuna ati pe a tu ojutu silẹ sinu awọn ọna omi agbegbe.
Lati dinku iṣelọpọ ti ẹrẹ pupa ati jade alumina diẹ sii ni ibẹrẹ ilana, ST Equipment & Technology ká oluya igbanu tribo-electrostatic can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Abajade ni imularada ti iye nla ti alumina, lilo kekere ti omi onisuga caustic ti o gbowolori, and a reduced need for red mud-holding ponds. A reduction in the amount of energy needed during the Bayer process to heat and pressurize the mined materials.
ST Equipment & Ipinya igbanu Imọ-ẹrọ jẹ tun ṣiṣe lalailopinpin lalailopinpin. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, idinku awọn idiyele gbigbe.
Ninu awọn ọrọ miiran, o yoo fi owo pamọ lori ṣiṣe, making more money on the additional alumina. You’ll be pulling from the feed material, and you can present your mining company as an eco-friendly operation. It goes a long way toward building a good reputation with the locals.
