The present invention relates to a system and a method for metal recovery from waste water including indium. More specifically, an embodiment of the present invention comprises: a first reaction tank from which a first solution is generated comprising molybdenum (Mo) and tin (Sn), and a second solution comprising indium (In) and copper (Cu) from a reaction of waste water which includes indium which consists of indium, tin, molybdenum, and copper and of a cyanex solvent which consists of a cyanex mixture; a second reaction tank from which the second solution is delivered from the first reaction tank, from which a third solution is generated including indium, and a fourth solution which includes copper from a reaction of the second solution, and of a depa solvent which consists of kerosin and a depa mixture; a third reaction tank from which the third solution is delivered from the second reaction tank from which indium is precipitated from a reaction of the third solution and hydrochloric acid. The indium precipitated from the third reaction tank is filtered and collected with a first filter. |
