The treatment of industrial mining wastewater (IMWW) by electrocoagulation (EC) using aluminumelectrodes has been conducted with real wastewater taken from a mining industry. For reuse this water,several experiments were carried out in order to optimize the conditions of technique applicability.2 The results showed that turbidity (560 NTU) was removed reaches 99% at current density 10 mA/cm ,free pH 7.2 and temperature of wastewater ~ 20 C. The clarification of IMWW is very quick (EC time< 10 min) and adequately described by pseudo-second-order kinetics model. Moreover under optimalconditions, all parameters of pollution measured after EC are below the standard norms of industrialdischarges. The EC process can be applied 10 times without loss of efficiency, it led to a minimal3 3 volume of sludge (65-75 cm /L), and a low cost treated effluent ~ 6 $/m .
