How to Separate Copper from Lead by Cu Depression

Apr 16, 2015  To achieve this copper/lead separation, bulk flotation is performed with depressants to control sphalerite and pyrite. Cyanide was used in the bulk rougher as it will also be used in the reverse. Rougher testing indicated that 10 to 50 g/tonne cyanide in the bulk rougher was sufficient. The bulk concentrate was then subjected to relatively high ...

Lead-Bismuth Flotation - Mineral Processing Metallurgy

Feb 28, 2016  Considering the fact that lead and bismuth are very close in the periodic table (number atomic: 82 Pb, 83 Bi), they can have similar behaviour during flotation. It means that collection and depression is very similar for both. So, applying the lead-copper separation technique is possible separate bismuth and copper too.

How to Process Copper Lead Zinc Ore with Gold and Silver ...

Apr 27, 2016  The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.

Architecture Design Handbook: Fundamentals - Copper

In areas with severe exposure, lead or similar gasketing materials should be used, except between copper and aluminum. Regardless of the method used to separate the metals, wash from copper surfaces should be prevented from draining onto exposed aluminum. Traces of copper salts in the wash may accelerate corrosion of the aluminum.

Liquation - Wikipedia

Liquation is a metallurgical method for separating metals from an ore or alloy.A mixture of metals is melted together with a third, after which the mixture is separated by liquid extraction.This method was largely used to separate silver from copper using lead, but it can also be used to remove antimony minerals from ore, and refine tin

Lead-Tin distillation furnace is highly recommended for tin lead separation. Metalcess uses multiple-stage distillation to reduce tin loss in lead vapor for better separation effect, producing crude tin (Sn >99%) and crude lead (Pb> 98%). Through fire refining, we can get high purity tin (Sn >99.995%) and high purity lead (Pb> 99.995%).

Copper - Lead Separation by Lead Depression

May 08, 2015  Copper in the feed was 77% recovered to the copper concentrate grading 18.2% copper. The lead grade of the copper concentrate was 6.1%. Lead was preferentially depressed from the concentrate; however, the separation efficiency was relatively low and resulted in significant lead recovered to the copper concentrate.
