Flotation | ore dressing | Britannica
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey ParrottSheffer, Research Editor.

Flotation of Iron Ore: A Brief Review MDPI
This is why reverse anionic flotation of iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment (, above pH 11). Fuerstenau and Cummins [28] concluded that, when oleate was used as collector, the suitable pH value was between 11 and 12 in the flotation of quartz.
