摘要

在将人造资源节约型添加剂回收利用为氧化铝原料的过程中,对用于旋转炉和其他热力设备内衬的废弃粘土耐火砖进行了测试。实验证实,从粘土衬里中提取氧化铝的水平足够高。经证实,当超过 95 000 吨储存的耐火粘土砖废料参与技术工艺时,可节约天然原料资源:约 56 700 吨霞石矿石。

Extraction of Valuable Components in the Process of Recycling of Technogenic Materials of Alumina Production
In the process of recycling man-made resource-saving additives into alumina raw materials, waste fireclay refractory bricks used for lining rotating furnaces and other thermal units were tested. A sufficiently high level of aluminum oxide extraction from fireclay lining has been experimentally confirmed. It has been established that when more than 95 000 tons of stored refractory fireclay brick waste is involved in the technological process, savings on a natural raw material resource are achieved: about 56 700 tons of nepheline ore.
