01/11/2001  A complex copper/lead—zinc ore from the Raura plant (Peru) that contains secondary copper minerals was studied with respect to improving copper/lead separation from the copper/lead bulk concentrate. As with most Peruvian plants that treat copper/lead—zinc ores, the Raura plant uses a dichromate separation method, which is ineffective due to the presence of secondary copper

Either of these or a red lead primer can be effective in separating copper from iron and other ferrous metals. Taping or gasketing with nonabsorptive materials or sealants are effective methods of separating copper from all other metals. In areas with severe exposure, lead or similar gasketing materials should be used, except between copper and aluminum. Regardless of the method used to ...

separation of copper from lead

Separation of arsenic and valuable metals (Pb, Zn, Cu, Bi, Sn, In, Ag, Sb, etc.) is a core problem for effective utilization of high arsenic-containing copper smelting ashes (HACSA). This study developed an effective separation process of arsenic, lead, and zinc from HACSA via alkali leaching followed by sulfide precipitation.

Abstract The extraction and stripping of lead from its acetate solution by LIX 64N diluted with Kermac 470B are reported. From these results, a process for the separation of lead from copper by co-extraction and selective stripping has been proposed. Very good co-extraction and selective stripping efficiencies were obtained which indicated that a high degree of separation between copper and ...

Liquation - Wikipedia

The copper-lead alloy created can be tapped off and cast into large plano-convex ingots known as ‘liquation cakes’. As the metals cool and solidify the copper and the silver-containing lead separate as they are immiscible with each other. The ratio of lead to copper in these cakes is an important factor for the process to work efficiently ...

Gold parting - Wikipedia

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...

Silver processing Britannica

A typical ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony. After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony. Approximately 25 percent of the silver produced comes from ores actually mined for their silver value; the other 75 percent comes from ores that have
