ABSTRACT

AIM:

To study the mechanism of foam floatation in the processing of Indigo Raturalis,and provide theory to support the industrialization of Indigo Raturalis processing by foam fioatation technique.

METHODS:

To study the critical problems of the processing of Indigo Raturalis by foam floatation technique the change of particle size distribution after the processing of Indigo Raturalis;The surface activity of frothing materials in Indigo Raturalis;the distinction of the foam to absorb the Indigo particles and other particles(CaCO_3);the absorbability of the Indigo particles to absorb different surface active agents.

RESULTS:

1.The Indigo particles were easily absorbed by the foam,but others(CaCO_3) were not;2.There were some frothing materials with good frothing capability in the alkaline system of Indigo Raturalis,3 In the alkaline system,the Indigo particles could be absorbed by the foam of strong acid surface active agents.

CONCLUSION:

In the alkaline system of Indigo Raturalis,with itself surface active agents,it is effective to process Indigo Raturalis by foam floatation technique.
