The southern Florida phosphate deposits that will be mined in the future contain significant amounts of dolomite. Because high MgO levels are undesirable in phosphoric acid production, several flotation schemes for the removal of the dolomite have been attempted. Alternatively, selective flocculation has been suggested as a potential process.A high MgO …

What are iron ores in mining? Iron ores are naturally occurring minerals from which iron (Fe) can be extracted economically. The primary iron ore minerals include hematite (Fe₂O₃) and magnetite (Fe₃O₄). These ores are characterized by their high iron content, making them valuable for the production of steel and other iron-based products.

Separation of dolomite from Florida phosphates was achieved by first conditioning the feed with fatty acid at pH 10 followed by reconditioning at pH 4 or below, before flotation. Observed selectivity of this two-stage conditioning process was attributed to the amount as well as changes in the nature of adsorbed collector species upon reconditioning. In this paper, …
