crude Copper refining-purity Machine
Copper electrolysis ,First,makes the crude copper which contains 98%-99.9% copper pouring into anode plate ,and use the pure copper sheet as cathode,then put them into the electrolytic cell (which has the copper sulfate and sulfate solution);
Under the effect of direct current,the anode copper and poorer negative metal will be dissolved into the electrolyte,but the Gold, silver, palladium and other precious metals can't be dissolved, and they will be made into anode mud;
The copper which in the solution will be separated out preferentially, poorer metal that can't be separated out will stay in the solution ,they will be removed when purifying the electrolyte, that cathode will separate out more purer copper(99.99%), it will be called cathode copper or electrolysis copper.
| model | Customizable |
| product name | Silver extractor |
| purpose | Recovery of precious metal wastewater |
| Applicable Industries | Gold and silver jewelry manufacturing |
| Product use | Recovery of precious metal wastewater |
| Specifications | 85*65*56 |
| production capacity | 10kg/15kg (24 hour) |
| Working principle | Put the old 925 silver jewelry into four titanium baskets, and then add 10% nitric acid solution to the machine. During the operation of the machine, the silver will be dissolved in dilute nitric acid solution, and then the silver in the solution will be electrolytic reduced by electrolyte and adsorbed on the rotating anode titanium barrel again, and finally obtain silver with purity of 9999 or 99999 |
