Separation by Flotation

Separation and Purification Methods, 1978
Abstract There has been much recent activity in the theory and application of separation by flotation, both in the United. States and abroad. This review primarily addresses new developments in foam flotation, colloid flotation and precipitate flotation.

CELESTITE-GYPSUM SEPARATION BY FLOTATION

Canadian Metallurgical Quarterly, 2008
AbstractThe celestite ore from Sivas, Turkey which was subjected to this experimental study contained mainly celestite and gypsum as gangue minerals. Flotation behaviour of pure minerals, celestite and gypsum was investigated using oleate and sulphonate as collectors in a Hallimond tube.

Separation of fines by flotation techniques

Separations Technology, 1993
Abstract A large amount of valuable minerals is discarded today as fines and ultrafines because of inadequate technology to process them economically. Treatment of fine particles presents a difficult problem in the chemical industry and raw materials processing, and its solution is required both in production and effluent treatment.

Flotation separation of waste plastics for recycling—A review

Waste Management, 2015
The sharp increase of plastic wastes results in great social and environmental pressures, and recycling, as an effective way currently available to reduce the negative impacts of plastic wastes, represents one of the most dynamic areas in the plastics industry today.

Heterocoagulation of chalcopyrite and pyrite minerals in flotation separation

Advances in Colloid and Interface Science, 2005
Heterocoagulation between various fine mineral particles contained within a mineral suspension with different structural and surface chemistry can interfere with the ability of the flotation processes to selectively separate the minerals involved. This paper examines the interactions between chalcopyrite (a copper mineral) and pyrite (an iron mineral ...

The separation of proteins from their misxtures using flotation

Colloids and Surfaces, 1985
Abstract The physico-chemical principles for the selective separation of of proteins from mixtures using flotation were studied. Adsorption isotherms as well as the maximum surface excess were determined by surface-tension measurements at different protein concentrations. Measurements on solutions of the same proteins at various pH values showed that
