Abstract

AT the meeting of the Institution of Mining and Metallurgy, held on November 20, a paper entitled “A Contribution to the Study of Flotation” was presented by Mr. H. Livingstone Sulman. After giving a brief historical review of the development of flotation as applied to ore extraction, with the problems that arose in connection with successive phases of the process, Mr. Sulman dealt principally with froth flotation, which he characterised as the final link in a long chain of effort. The essentials of this process are that an aqueous pulp shall be agitated with certain reagents which may be classified as a “froth-producing” material, a “froth-stabilising” substance, and a “gangue-modifying ” addition.
