Experimental Research on Products Preparation by Hongquan Bentonite from Gansu

We selecte two bentonite products: activated clay and organo-bentonite, and introduce the related content of them like industrial applications, technology and raw materials of producting at the same time. After that, we choose the preparation processes of activated clay and organo-bentonite. Choose conditions of the prepared samples, arranging test methods by orthogonal test program, and preparing of the activated clay and organo-bentonite samples in accordance with the different test conditions. Finally, we draw this conclusion according to the test analysis and demonstration results. We propose the recommendations of the development of activated clay and organo-bentonite by Hongquan bentonite, pointing out that the shortcomings of this study and proposing pilot study of future.
