Abstract
A copper sulfate electrolyte production method includes a copper melting step of producing molten copper by melting a raw material containing copper (Cu) in a melting furnace, an atomizing step of producing copper powder by spraying the molten copper with an atomizer, a leaching step of forming a copper sulfate solution by dissolving the copper powder in a leaching step input solution in a leaching reactor, a purification filtration step of removing impurities contained in the copper sulfate solution, and a conditioning step of preparing an electrolytic feed solution by mixing an electrolytic cell circulation liquid with the copper sulfate solution from which the impurities are removed in an electrolytic cell.
