| Abstract: | The chemical compositions of bentonites from various parts of China were investigated. The differences among different ore samples and deposits were examined. The correlations in chemical composition were analyzed. The results showed that variations in contents of Si and Al are the main factor that could control the chemical composition of bentonite. The Mg-rich environment is favorable to the formation of bentonite; little difference is noticed in Ti contents of the samples analyzed. |
| Keywords: | bentonite montmorillinite chemical composition |
