Mining & Mineral Processing 8 Mining & Mineral Processing Tailings Tailings are the materials left over after separating the valuable minerals from the unusable portion of an ore. Tailings are distinct from overburden or waste rock, which are the materials overlying an ore or mineral body that are displaced during mining without being processed.
Dredging Tailings. Reclaiming or eliminating mine tailings through dredging is a fundamental operation that keeps some mines operating efficiently. Typical tailings applications for Ellicott® brand dredges are, amongst others, in the coal, iron ore, gold, and oil sands sectors.

Iron ore tailings (IOTs), as a waste from the mining and mineral industry (Osinubi et al., 2015), can be an ideal candidate for aggregate in this concern. IOTs were generated during the removal of overburden for ore with a waste-to-ore ratio (stripping ratio) that varies from 2:1 to 5:1 ( Yellishetty et al., 2008 ) or 2.5:1 to 3:1 ( Ma et al ...
