Copper Nickel : Materials Selection in Sea water systems

The use of 70-30 Cu-Ni is confined to submarines where its high strength is advantageous. Due to the low design velocity and hence large pipe sizes, copper is uneconomical except for small diameter piping for essentially domestic applications, so that the real choice is between 90-10 Cu-Ni and aluminum brass.…

Float Metals One-by-One Selectively: Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe: pH 6-6.5 is where Pb/Zn/Fe are least hydrophobic while Cu is most hydrophobic. Great pH to Recover Cu.…

Sequential Copper–Lead–Zinc Flotation

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and .…

Froth Flotation (Sulphide & Oxide)

It is easier (proven) to selectively float galena by depressing sphalerite than the other way around if you are trying to make two concentrates. Bulk (or combined Pb/Zn) concentrate is the quickest way into bankruptcy because of heavy penalties imposed by smelters which becomes a real issue if your concentrate happens to contain Gold and Silver.…
