| titleOfInvention | Process for recovering copper from waste circuit board to prepare high purity and high strength copper foil based on electrochemical method |
| abstract | The present invention discloses a process for recovering copper from waste circuit board to prepare high purity and high strength copper foil based on the electrochemical method. According to the process, a copper sulfate-containing solution is adopted as an electrolyte, waste circuit board is adopted as an anode, an industrial titanium plate or stainless steel plate is adopted as a cathode, electrolytic deposition is performed through direct current or pulse current, and the copper foil is obtained at the cathode, wherein the thickness of the prepared copper foil is less than or equal to 16 [mu]m, the tensile strength is 300-400 Mpa, the purity is more than 99.9%, the resistivity is 2.5*10＜-6＞-4*10＜-6＞ [omega].cm, and the corrosion resistance is good; and the process has characteristics of low cost and environmental protection, the copper recovery rate is up to more than or equal to 90%, the operation can be achieved by using the mature electrolysis industry apparatus in the prior art, and the industrial production is easily achieved. |
