Recent results at the Inspiration mine would indicate some advantage (on that ore, at least) in running the cells in series of two instead of parallel, and without any sace in capacity for a certain set number of cells. On an ore carrying a large percentage of mineral there is not much doubt that the series plan will give the best results ...
Laboratory flotation tests were performed in triplicate in a four litre Denver flotation cell; however, the host mine procedure used a three litre cell. A mixture of collectors and frothers were employed, with lime to control the process water to pH10. ... For the porphyry copper ore tested in these investigations, a coarse copper sulphide ...
