The Rheological Properties of Water Suspensions of Finely Subdivided Magnetite, Galena and Ferrosilicon
Measurements of the settling rates and the rheological behaviour of heavy media formed of fine suspensions in water of each of magnetite, ferrosilicon, and galena have been made. For media ranging from 1.6 to 2.8 specific gravity the settling measurements gave initial settling rates of from 0.5 to 0.'01 •cm. 'Per minute for magnetite; from 4.0 to 0.8 cm. per minute for galena; and from 35 to 1.6 cm. 'Per minute for ferrosilicon. These measurements indicate the •relative stability of the suspensions and should be helpful in establishing the useful specific gravity range for each medium.
