Abstract:
Processes of consolidating phosphate tailings, which include solids and process water, from phosphate mining and extraction operations are disclosed. The processes include mixing the tailings with a highly water soluble salt or an aqueous solution thereof to destabilize and consolidate solids in the tailings and separating the consolidated solids from the process water.
