Abstract
A method is provided for recovering barium sulfate from a contaminated water source comprising barium cation. The method involves combining the contaminated water source with a source of sulfate ion, thereby forming a modified contaminated water source. The method includes forming precipitated barium sulfate within the modified contaminated water source; isolating precipitated barium sulfate from the modified contaminated water source, thereby forming isolated precipitated barium sulfate; dewatering the isolated precipitated barium sulfate, thereby forming a low-moisture precipitated barium sulfate; combining the low-moisture precipitated barium sulfate with clean water to form a slurry comprising precipitated barium sulfate; subjecting the slurry to density separation to form a refined barium sulfate; and subjecting the refined barium sulfate to particle size reduction and/or particle size classification to yield a recovered barium sulfate.
