Electrodeposition behaviour of copper from ore leachate and copper ammonium sulphate

Pulsed Electrodeposition of Copper

Pulsed electrolysis of copper has been systematically investigated by electrodepositing copper from a copper sulfate bath. Pulse duty cycles of 5 to 80 percent, at frequencies from 10 to 100 Hz with current densities ranging from 2.5 to 7.5 A/dm2 were employed. The appearance of Hull Cell panels with both direct current and pulsed current was recorded. The influence of pulsed current on current...

Copper Sulphate and Disinfection of Water

lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...

Optimization of parameters affecting recovery of copper from Sarcheshmeh low-grade sulfide ore using Bioleaching

In this work, the parameters affecting the recovery of copper from the low-grade sulfide minerals of Sarcheshmeh Copper Mine were studied. A low-grade sulfide ore was used with a copper grade of 0.25%, which was about 28% of the mineral oxide, and the sulfide minerals made up the rest. Much more sulfide minerals were found to be pyrite and most of the gangue minerals were quartz, anorthite, bio...
