| Abstract: | The basic chemistry and mineralogy of red mud discharged from Bayer and Sintering Combination process is studied such as pH,EC,dissolution and exchange of base ion and X ray analysis of minerals in Zhengzhou Alumina Refinery,covering fresh red mud,five year red mud and ten year red mud.In addition,acid counteragent of the three different of red muds is studied with two-year low velocity relay titrimetric method.Fresh red mud with the most acid counteragent is selected to be used as improver to measure its effects on acid of mine earth,activity of heavy metal in earth and the growth of plants. |
| Keywords: | Red mud chemistry and mineralogy utiliztion of resources |
