On activation and depression of quartz and martite
Abstract
For flotation of iron ores by fatty acids (tall oil) in the conditions of the Krivoy Rog basin, the influence of salt composition of water on flotation is of particular importance, as the technical water of enrichment plants is diverse in its composition and has a high hardness. Changing the composition of water under the action of lime, soda and caustic soda amounts to its softening. The pH required for sufficiently complete softening is determined, according to I.E. Apeltsin, depending on the initial hardness, total salinity, temperature, time, and final hardness. Fig. 1 shows that by the joint action of lime with soda and caustic soda with soda, the hardness of the technical water of CGOK is reduced.
