China's alumina industry from scratch to rapid development, has a history of about 70 years. Since the first aluminum oxide plant was built in Shandong, aluminum oxide plants have been gradually built all over China, it can be said that the pace of expansion of China's aluminum oxide industry has never stopped.
Alumina can be divided into two categories according to different uses: metallurgical grade alumina used as a raw material for the production of metal aluminum by electrolysis, and non-metallurgical grade alumina (also known as special alumina, multi-variety alumina or chemical alumina). These two important basic raw materials not only provide a strong support for the development of light metal industry, but also provide a lot of opportunities for the development of related industries, and play an important role in national economic construction, national defense construction, social development and stable employment.
In recent years, with the rapid development of China's alumina industry, China has become the world's largest alumina production and consumer. At the same time, the development of new material technology has also led to the transformation and upgrading of many traditional industries, and the focus of the alumina industry has gradually moved from "output" to "quality" due to the improvement of downstream application requirements. What is the status quo of alumina quality in China? Although I want to give a quick answer, but because of the many standards to measure the quality of alumina, the analysis is not a simple matter.
