The Development Of A Treatment Process For The Mine Water Containing Arsenic And Thiocyanate From Lab Scale To Pilot Plant Scale

Abstract : About 8 million metric tons storage of cyanidation tailings from a former French gold mine produces a 10 m 3 /h mine drainage that contains around 8 mg/L of As and 1 g/L of SCN-and is currently treated with a lime process. The existing treatment plant produces large amounts of sludge reflecting the large amounts of sulfate present in water and calcium from lime. The present study aims to developing a semi-passive mine water treatment process that would produce a lower amount of sludge and improve the treatment efficiency with a target discharge level under 100 µg/L of Arsenic.
