The dimensions of nonsulfide flotation technology extend in many directions, as might be expected from the diversity of the mineral classes, which include soluble salt minerals (potash, borax, and trona), semisoluble salt minerals (phosphate minerals, fluorite, calcite, and barite), and insoluble oxides/silicate minerals (iron oxide minerals, rutile, mica, quartz, and feldspar).

Many approaches were pursued to solve the sulfide problem at Broken Hill before selective flotation was developed.
