Issued also in French under title: Revue des développements dans la flottation de la cassitérite : progrès et considérations physico-chimiques. Includes bibliographical references. "The development of cassiterite flotation has progressed along a varied and diverse course. Early experimentation was restricted mainly to the use of either alkyl carboxylate or alkyl sulphate collectors, and selectivity depended on an optimum combination of activator, depressant and pH modifier. Current developments are concentrating on either synthesizing selective collectors of the arsonic, phosphonic, sulphosuccinamate and humic acid derivatives, or exploring the possibilities of new techniques such as electroflotation and dissolved air flotation"--Abstract, p. i.
