| titleOfInvention | Method for producing copper powder from acidic copper chloride waste liquid |
| abstract | The present invention relates to a method for recovering copper from printed circuit board cleaning waste liquid using the wet method. The present invention is a method of recovering a high-purity, fine particles of copper powder from an acidic copper chloride waste liquid, more specifically, by reducing the reducing sugar in the acidic copper chloride waste liquid and then reacted with an aqueous alkali solution, the precipitated slurry is filtered, washed and hydrazine is used. To produce a copper powder. According to the present invention, high-purity, fine particles of copper powder can be produced in an economical manner from acidic copper chloride waste liquid which is industrial waste.n n n Acid, Copper Chloride, Waste Fluid, Copper, Powder, Hydrazine |
