E Waste PCB Circuit Board Recycling Machine is used to recycle all kinds of Printed Circuit boards, such as the computer boards, cell phone boards, TV boards, copper-clad laminate, and other appliances, and the separation of leftover material of the mixed metal and nonmetal materials. Cost-effective recycling of e-waste (from computer printed circuit boards, PCB’s) for the synthesis of metal oxide nanocomposites is demonstrated. Metals in electronic components of waste memory slots were leached out using nitric acid (HNO3). Compositional analyses of the filtrate obtained after leaching were 66 wt.% Cu, 27.7 wt.% Zn, and 6.2 wt.% Ni.
