Concern for the environment, water scarcity and greater regulation of the mining industry combine to make rigorous water treatment important and necessary to the mining industry. Thickeners are the first step in separating finely ground ore from process fluids after the metals have been extracted. Ore particles sink to the bottom of the thickener tank and the thickener drive turns rakes that gather the solids for further processing. Eventually, these spent solids are disposed as mine tailings. Used thickeners that will handle heavy mine-duty loads are often available in reputable brands like Eimco, Dorr Oliver, WesTech, Denver and Enviro-Clear. D’Angelo International can also provide new OEM, bolt-in replacements for most thickener drives.
