[0018] First, collect the waste copper slag from the copper smelter, wash it, dry it naturally, and then grind and sieve it to prepare 60-mesh copper slag particles, collect the copper slag particles, put them in a crucible, and move the crucible to a tube furnace , pass oxygen through it to remove the air, and then heat it up to 500°C under an oxygen atmosphere, and heat-preserve and calcinate for 2 hours; Slag powder, sieve the copper oxide slag powder with a magnet. After the magnetic separation is completed, place it in a ball milling device, use absolute ethanol as a dispersant, ball mill for 5 hours, and then dry naturally to prepare a ball milling mixed powder; press In terms of parts by weight, weigh 50 parts of 30% citric acid solution, 30 parts of glacial acetic acid and 20 parts of the above-prepared ball-milled mixed powder and place them in a three-necked flask, heat in a water bath at 60°C for 5 hours, then filter and collect the filtrate , to prepare the acidifi...
