think so by electrolytic refining
What is the difference between electrolytic reduction and electrolytic refining under these heads a. electrodes b. electrolytes c. reaction at positive and negative electrodes?
The difference between electrolytic refining and electrolytic reduction is as follows: a. In electrolytic reduction graphite electrodes are used which are of same size. in electrolytic refining the anode is made of the impure metal which is to be purified and the cathode is made from that pure metal. initially the cathode is thick and the anode is very thin. b. the electrolyte used in electrolytic refining is the metal sulphate with acid (acid id added to increase the conductivity) which is aqueous in nature. whereas in electrolytic reduction molten chloride form of the solution is used. c. The impure metal at the anode displaces the metal from the aqueous solution and the these ions go to the cathode and attach to the cathode as they are now pure. basically the impure metal at the anode directly doesn't go to the cathode, its a indirect process. as the reaction goes on, the size of the anode reduces and finally disappears and the cathode becomes thick as all the impure metal is converted into pure metal. this happens in electrolytic refining. whereas in electrolytic reduction the metal from the molten solution deposits on the cathode and chlorine gas is evolved at the anode. general differences: a. in electrolytic reduction no anode mud is formed and in electrolytic refining anode mud is formed from the impurities oh the impure metal. b. electrolytic reduction is done to extract metals of high reactivity from their ores. electrlolytic refining is done to purify (refine) metals from their impure form.
Can you use alternate current in the electrolytic refining of copper?
No, it causes an electrolysis that occured to be undone.
What has the author T Ulke written?
T. Ulke has written: 'Modern electrolytic copper refining'
What are the various methods of concentrating ores?
They are Froth floatation, Gravity separation Hydraulic ores and Electrolytic Refining.
Can you explain why oil filled capacitors must be used for capacitor run motors instead of the more economical ac electrolytic types?
Electrolytic capacitors cannot be used on an AC (alternating current) system.
What type of circuit would you find an electrolytic capacitor?
Many, but a near guaruntee would be any power supply. Electrolytic capacitors are the ones that look like batteries.
What would you use to electroplate silver iron?
