A novel electrode is provided which is particularly useful as an anode in an electrowinning system for the electrodeposition of copper from acid solution. This novel electrode is an alloy of lead and bismuth containing from 95 to 70 parts by weight lead with corresponding proportions of 5 to 30 parts by weight bismuth. The use of this electrode as an anode in conjunction with conventional ...
Silica in the extraction of copper. Cryolite in the extraction of aluminium. Iodine in the refining of Zirconium. Sodium cyanide in froth floatation. Answer: 1. The role of silica in the extraction of copper is to remove the iron oxide obtained during the process of roasting as slag. If the sulphide ore of copper contains iron, the silica (SiO ...
12/6/2019· Because the method is based on preferential wetting properties with the frothing agent and water, and the sulphide particles of ore stick to the oil droplets and rise in the form of froth. ...

Typical Families of Flotation Frothers – Frothing Agents The dosage of frother required in any given application is quite variable, ranging from zero in some systems to 0.3 kg/ton in others. Part of the reason for this variability is that many collectors presented earlier demonstrate some frothing action as well as collecting action.
