Investigations on flotation of copper-nickel ore [electronic resource] / W.R. Honeywell and F.J. Kelly, Extraction Metallurgy Division. Ottawa : Information Canada, 1970. iv, 21 p. : charts Technical bulletin ; TB 128 Cover title. "August 1970." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “An investigation was carried out on a copper-nickel ore to develop flotation methods to produce a bulk copper-nickel concentrate. The effects of grind, pH and collector reagent additions, on recovery, grade, kinetic flotation rate and the probability that mineral particles will float, were determined. All correlations were done by regression analysis techniques. The test work yielded significant empirical models that relate the nickel metallurgy of the system to changes in operating variable levels. With the exception of recovery, no significant correlation between the operating variables and the copper responses of the system was established"--Summary, p. i.
