Ore Treatment - an overview ScienceDirect Topics

Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.

Adsorption of etheramine on kaolinite: A cheap

The adsorption of etheramine on kaolinites was better fitted to the Langmuir rather than the Freundlich isotherm, and could be explained by a pseudo-second-order kinetic model. It is concluded that kaolinites offer significant potential in the treatment of effluents originating from the processing of lower grade iron ores by froth flotation.
