Studies on the adsorption of flotation collectors

Calcium ions were found to significantly enhance the adsorption and possibly induce precipitation of the collector on magnetite even in the presence of sodium silicate suggesting that a high concentration of calcium in the process water could possibly enhance the contamination of the iron ore with the flotation collector, which has been previously shown to have a negative effect on both flotation and
