Strip mining is efficient, but scars the land and bauxite processing releases a toxic red sludge that can seep into water supplies if not adequately contained.
The description focuses on bauxite dressing, digestion of concentrated bauxite, and red mud settling as well as impact of floatation agent on the production and improvement in agent.
着重讨论了铝土矿选矿过程、选精矿溶出过程、赤泥沉降过程以及浮选药剂对生产的影响和改进。
