Electrolytic Zinc - 911 Metallurgist

2020-11-8  It is right here that the basic difference between the retort process, or electrothermic process, and the electrolytic process comes in. The power consumption for the latter plant is practically independent of the grade of ore treated, and it is virtually 4000 kw.-hr. per ton of zinc output regardless as to whether that zinc is made from 60-per cent, zinc concentrates or from 25-per cent, zinc

ELECTROLYTIC ZINC WORKS - Engineers Australia

Electrolysis – Zinc metal is recovered from the purified solution in electrolytic cells by the passage of an electric current. The zinc metal is deposited onto aluminium cathodes and oxygen is generated at the lead anodes. The zinc deposits are periodically removed, or stripped, from the cathodes. The stripped zinc is melted and cast into the various products such as special high-grade zinc (99.995% zinc) and die-casting alloys. When zinc is produced at the cathode sulphuric acid is generated and the zinc depleted solution, called spent electrolyte, is returned to Leaching to dissolve the zinc
