Liquation - Wikipedia
Liquation is a metallurgical method for separating metals from an ore or alloy.The material must be heated until one of the metals starts to melt and drain away from the other and can be collected. This method was largely used to remove lead containing silver from copper, but it can also be used to remove antimony minerals from ore, and refine tin
How to Separate Copper from Lead by Cu Depression
Copper recovery to this concentrate was only 3%. For the same three tests, copper was 57% recovered from the feed into a concentrate grading 27% Cu. The average lead grade was 5%. Copper recovery was low in the batch test as there was significant copper remaining in the bulk Flotation cleaner tailings.

24-7-2011 · separate lead from copper-Can you melt it? Reloading Bench. Advertise Here. Forum Reviews Rules Legal Site ... Bring it just above the melting temperature of lead, maybe 550 degrees F, and the lead melts. The lighter copper (which requires about 3 times as much heat to melt) floats on top of the molten lead.
Copper Lead Concentrate Separation
When copper-bearing minerals are to be separated from galena, the first step generally consists of the “bulk flotation” of both classes of mineral in one copper-lead concentrate by the use of reagents very similar to those employed in the lead flotation section of a lead-zinc plant.
A possible way to remove zinc from molten lead
2-10-2009 · While researching the true meaning of 50:50 solder, I came upon some information describing how to make different solder mixtures. Part of the article mentioned how a very small amount of zinc will "poison" the solder and goes on to explain how to remove the zinc by fluxing with sulfur. Perhaps this has been brought up before but the information was new to me.
How to Remove Copper from Silver | Sciencing
However, it is not easy to find silver in its pure form. It is often found in metallic ores that contain quantities of other metals, such as copper. To separate silver from an ore containing a quantity of copper, you need to heat the ore sample to a level sufficient to melt the silver but leave the copper in a …

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 ...

7-10-2008 · The mix of metallic copper and silver can be washed free of copper and lead chlorides by first using saturated salt solution, then hot water. Treating of the mixed metals with sulfuric acid can dissolve most of the copper.
Ways to Separate Metal From Ore | Sciencing
The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech, and are applied to a variety of materials, including aluminum, iron and copper.
