The amount of waste electrical and electronic equipment (WEEE) in the world has grown rapidly during recent decades. This paired with the decrease in grade of primary sources for metals emphasizes the industry to study new sources for metals. Waste printed circuit boards (WPCB) are a part of WEEE, that has higher concentration of copper and precious metals when compared to primary ore sources. PCB material can be processed using pyrometallurgy and is already done in some processes, such as copper flash smelting. In this thesis the behavior of printed circuit board scrap was studied when it was dropped on top of molten slag. The subject was studied by using literature sources and experiments. The theoretical part defines the general compo...
