现有铝工业企业的发展前景,是向无尾矿和少尾矿生产过渡,实现这一过程主要是依据: 1、减少所形成的固体尾矿的数量并加以利用; 2、建立回水供水系统; 3、减少向大气圈排放有害物质的量。氧化铝生产的矿泥占化工冶金部门生产中每年所形成的固体尾矿总量的80%以上。因此,在铝工业部门中建立无尾矿生产的主要方向是合理利用这种固体尾矿。沃尔霍夫炼铝厂和皮卡列夫氧化铝厂的霞石矿泥全部地制成了水泥。但是,阿琴斯基氧 The current development prospects of the existing aluminum industrial enterprises are the transition to tailings-less and tailings-less production. The realization of this process is mainly based on the following measures: 1. Reduce and utilize the amount of solid tailings formed; 2. Establish backwater supply System; 3, to reduce the amount of harmful substances emitted to the atmosphere. The slime produced from alumina accounts for more than 80% of the total amount of solid tailings formed in the chemical and metallurgical sectors each year. Therefore, the main direction for establishing tailings-free production in the aluminum industry is to make rational use of this solid tailings. The nepheline slimes from the Volkhov smelter and the Picarev alumina plant are all made of cement. However, Achinski oxygen
