Abstract
Along with the development and industrialization of societies, the demand for heavy metals is on the rise, while the rich mineral ores of these metals have declined. Today, other sources of metals with higher grades, such as spent catalysts, fly ashes, electroplating sludge, and most importantly, electrical and electronic wastes have been taken into consideration. Recovery of heavy metals from these secondary sources by conventional methods such as pyrometallurgy and hydrometallurgy has some disadvantages including high energy consumption and high utilization costs, the risk of environmental pollution, and public health threats. Due to the strict environmental regulations, especially in the field of toxic waste disposal and also with the cost of applying these rules, there is a need for new, environmentally friendly, and more effective technology for recycling wastes. In this discussion, the methods of electrical and electronic waste recycling, which include pyrometallurgy, hydrometallurgy, and biohydrometallurgy have been studied. Among them, bioleaching has been introduced as an effective, inexpensive, and eco-friendly method.
