Establish modeling of recycling copper clad laminate scrap and making copper sulfate ABSTRACT This article builds a technology model for recycling copper clad laminate scrap from production electronic circuit board to recover crystalline copper sulfate and its by-product, recyclable bakelite plastic. After being chopped, scrap copper is dissolved with H2SO4 acid under oxidizing conditions to dissolve the copper. The resulting concentrated copper sulfate solution is cooled to crystallize to recover the copper sulfate. The remaining bakelite resin after separation is cleaned by washing with water. This plastic can then be used as a filler to produce a number of common items such as flower pots and construction materials..... The model shows an effective mehtod to recycle copper scrap, making the most of valuable components, thereby limiting environmental pollution and playing a role in promoting sustainable production in the electronics industry.
