알루미늄은 지구상에서 가장 흔한 금속 원소입니다.. 그러나, 오늘날 우리가 사용하는 알루미늄은 알루미늄 금속과 알루미나의 형태로 제공됩니다., 알루미늄 산화물이라고도 함, which is produced from bauxite. In order to release the raw alumina, bauxite must go through what is known as the Bayer process, where the bauxite is crushed, then heated in a pressurized vessel and dissolved with sodium hydroxide (caustic soda). The alumina is then separated from the other components and impurities contained in the bauxite so that it can eventually be refined into aluminum.
불행하게도, the waste left behind—called red mud—is toxic and must sit in holding pools until it can stabilize. These impoundments are often reinforced with clay or synthetic liners that keep the caustic materials from seeping into the surrounding soil or ground water. 그러나, there have been a number of instances when reservoirs of red mud have breached their confinements and caused catastrophic environmental issues.
세인트 장비 & Technology has a better way to produce alumina. The STET process removes the reactive silicates and inert oxides (Fe, Ti) from bauxite without the use of caustic materials or wet separation processes. Through our unique triboelectrostatic dry separation process, a greater degree of alumina can be extracted from the bauxite with before going through the Bayer Process. The remaining elements from the process can be used in ceramic production, as well as Portland cement manufacturing. The fine powder created by the process can be managed with water to prevent it from creating dust clouds, but the resulting “mud” does not contain caustic materials and is perfectly safe for the environment.
그래서, if you add up all the benefits, 세인트 장비 & Technology’s method is a much better alternative. It saves on operating costs by lowering the use of caustic soda, which is both a cost benefit as well as an environmental blessing. It also saves money by performing pre-Bayer processing of the bauxite, resulting in less energy needed to heat and pressurize the post-separated materials. And, 세인트 장비 & Technology process is energy efficient, so it can rapidly process a high volume of materials to keep mining operations moving forward.
