17/5/2012, · The selection of a treatment technology depends upon the characteristics of the wastewater and treatment goals. Treatment technologies for mining wastewater often employ pH adjustment to convert soluble salts in the waste water to less soluble hydroxide or sulphide salts, which then can be removed by physical means (i.e., settling, precipitation/clarification or filtration).
