China’s reform of the electrolytic aluminum supply chain and the significant expansion of foreign alumina’s production capacity in the future will lead to high profitability in the industry. However, emerging economies won’t be able to offset the drop in aluminum demand caused by China’s economic slowdown.
Since the Alumina Production Process has not changed over the decades, there is no way to expect the global problem of red mud being used in full-scale production.
Short description of red clay
An average of 1.5 tons was produced from each ton (about 0.088-0.25 mm) of alumina. This equates to a specific gravity of 2.7-2.9, a bulk density of 0.8-1 and a melting temperature of 1200-1250 C.
It is believed that most of China’s alumina production uses the Bayer method. Bayer’s method has high iron and aluminum levels.
Second: The case study of Alumina Enterprises in the full utilization of Red Mud
1. Chinalco Shandong Branch. Data shows that Chinalco Shandong Branch’s red-mud utilization is at 25%. Chinalco Shandong Branch also has 12 million red-mud accumulated, which is the highest utilization rates of China’s alumina businesses. Henan aluminum industry transformation and development action plan 2018-2021 clearly indicated that by 2020 the complete utilization rate will exceed 10%. The harm is incomparable. China’s redmud has a very low utilization rate. It is used to prepare new coal-burning technology desulfurizer technology, high grade cement, highway subgrade, brick manufacturing, and water purifying agent.
2. Weiqiao Group. In 2018, approximately 20,000 tons was consumed by the Binzhou Section of Jiqing Excursion’s 5.3-km road. The expressway’s kilometers can be consumed at least 200,000 tons. Provincial highways are capable of consuming 60,000 to 100,000 tons. Municipal roads may use up to 22,000 tons. China and other countries have large roads in China. This makes the potential market for them very attractive.
Third: A typical case where social forces are involved in the complete utilization of red soil
Shandong Satellite TV broadcasted news on Zibo Tianzhirun Ecological Technology Co. Ltd. (who uses large quantities 70,000 tons red mud annually to produce permeable masonry bricks). With a red permeable brick production rate of 91%, the company was recognized as one of 10 most important innovations in Shandong Province’s circular economy. While the firm’s boss was more than 30,000,000, Zui only had 2 houses. This is an international problem.
This isn’t just an indication of the fact Inner Mongolian firms have spent hundreds upon billions to create fly ash. But there has been no breakthrough.
Fourth – The complete red mud usage recommendations
Presently, red mud is used for cement production as well as for making permeable and roadbed bricks. Each option has its pros and cons. Even though cement technology is already mature, there is still a cement plant close by and roadbed use is substantial. But the demand in the future is very limited for areas that are economically well developed. Permeable brick production can still be promoted throughout the country. Unfortunately, this means that permeable bricks are much more cost-effective within 800 kilometers.
China’s complete utilization rate for alumina-red mud in China is quite low. Our utilization rate of red mud isn’t worse than other countries. However, this will not change in the near future. China’s new era in alumina has begun, and our company is now able to fully utilize the red mud. The company’s market position will be transformed by the profit margin.
