Water Separation and Flotation Processes
Journal of Field Archaeology, 1974AbstractThe water separator, a mechanical flotation device which is finding increasing usage among Mediterranean archaeologists, is compared with “tub” flotation which is widely practiced by North American archaeologists. The water separator was found to be two to three times more efficient than tub flotation.

Flotation and Liquid Separation Techniques
2001Liquid separation procedures can generally be assigned to one of two groups. (i) Gravity separation techniques: use a gravity difference between particles within a residue. The procedure’s success is considerably improved by using a liquid with a specific gravity (S.G.) value between the two main mineralogical components to be separated.

FLOTATION AND MAGNETIC SEPARATION PROCESSES FOR A MINERAL OF WOLLASTONITE
SGEM International Multidisciplinary Scientific GeoConference� EXPO ProceedingsThis paper presents the results of laboratory processing tests conducted to explore the potential for beneficiation of a wollastonite mineral (calcium metasilicate, CaSiO3). The ore studied comes from a mineralized body located in the southern part of Sardinia (Italy), which has been studied in the past with geological surveys and sampling.

A New Technique for Separating Flotation Samples
American Antiquity, 1986The seed blower is an instrument typically employed by seed technologists to sort seed types by density. Because of the labor intensive nature of hand separating flotation samples, the seed blower offers archaeologists a new apparatus that enhances the efficiency of initial separation.

Electrochemical Flotation Separation of Sulphide Minerals
2009This chapter is mainly about potential controlled flotation. First, the factors affecting potential controlled flotation are discussed, such as potential modifiers, pH modifier, frother, conditioning time, surface pretreatment and grinding environment.

Mixed Liquor Solids Separation by Flotation
Journal of the Sanitary Engineering Division, 1970A full-scale dissolved air flotation unit, designed for solids-liquid separation of an activated sludge mixed liquor, was evaluated in a field investigation. The data indicate that conventional design parameters do not predict flotation performance in terms of effluent suspended solids. A new parameter was developed and is proposed as a rational design

Mechanism of separating muscovite and quartz by flotation
Journal of Central South University, 2014Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FT-IR spectrum analysis, contact angle measurement and ...

The separation of monazite from zircon by flotation
Journal of the Less Common Metals, 1972Abstract The conditions for the separation of monazite from zircon in anionic (oleic acid and sodium dodecyl sulphate) and cationic (dodecylaminium chloride) collector systems using sodium sulphide as regulator have been studied by means of electrokinetic measurements, direct flotation tests, and adsorption determination of the collector. The results
