The article gives a description of factors which have influence on water consumption of ore washing in Pingguo Bauxite Mine, and proposes some improvement measurements which contribute to solving the problem of high consumption of water during ore washing and saving finite water resources.

This paper shows that in carbonization method for processing pseudo-boehmite,chamber filter press is replaced by horizontal vacuum band filter to wash pseudo-boehmite,spent washing water is recycled and reused,with improvement of cooling down process to reduce fresh water consumption,and efficient result in saving fresh water is finally achieved.

In this papers introduces that some new technology and management way used in a practice of the decreasing hot iron consumption at the LD's steelmaking plant of the xianggang.
