Recovery Of Copper From E-Waste Via Hydrometallurgy Method

E-waste production is increasing by time as the demand of society in electronics grows year by year. Since, e-waste contain both hazardous metals and precious metals such as copper, recovery of the metals are necessary to minimize environmental and to gain benefits from monetary metals. In this wo...
