| titleOfInvention | A kind of method for producing ferrous chloride by acid etching solution replacement |
| abstract | The invention discloses a method for producing ferrous chloride by replacing an acid etching solution. The method comprises the following steps: step 1: filtering the acid etching solution, filtering impurities and sending it to hazardous waste treatment; step 2: etching the acid copper-containing solution Add iron powder into the solution evenly and slowly, and stir to replace the copper in the acid etching solution once. The amount of iron powder added is the theoretical consumption of copper powder replacement in the solution. 100 mesh, control the reaction temperature not to exceed 90 ° C, step 3: continue to react for 2 hours after the iron powder is added, carry out liquid-solid separation of the solution, produce sponge copper, wash with water, return the washing water to replace once, and the washing residue is sponge copper, The method realizes the recovery of ferrous chloride in the copper-containing etching solution after the copper is recovered in the copper-containing etching solution through two replacements and then through evaporation and concentration, with low production cost, high economic benefit, zero discharge of waste water and high environmental benefit. |
