Datensatzbeschreibung

我国氧化铝生产中拜耳法、烧结法、混联法三种工艺并行。因为我国铝土矿主要为品味较低的一水硬铝，单位资源与能源消耗较高。随着生产技术的进步，拜耳法生产的氧化铝在我国铝产量中的比例已经由2000年的11.4%提升到2010年的75.8%，而烧结法则由2000年的23.65%减至5.9%。烧结法氧化铝生产过程中主要的能耗介质中煤占60%，蒸汽约20%，电约12%，其中煤主要消耗在烧成工序，蒸汽主要消耗在脱硅与蒸发工序，油主要消耗在焙烧工序。 [zh]

Technologiebeschreibung

Alumina produced using the sintering method is mainly utilized in the metallurgy industry for the production of aluminum via the electrolytic process. It is derived from bauxite, typically of a lower grade with higher resource and energy consumption. While the Bayer process is more prevalent in China's alumina production, the sintering method holds a small but specific share, catering to particular types of bauxite and specific production requirements.
