A study on evaluation method of flotation frother`s froth stability

Frother plays an important role in the coal flotation. The frothability of common frothers for coal flotation was measured by using gas pulsation method in this paper. The relationship between froth height and half decay time was analyzed. In this article, several well-known frothability evaluation methods will have been analyzed and compared, and a new method of evaluating froth stability will be given.
