The ways to obtain successful Separation of Copper and Lead into individual Concentrates, several process approaches can be examined; bulk copper-lead flotation with a reverse flotation stage depressing copper, the same bulk flotation with a reverse flotation to depress lead and a sequential copper-lead-zinc flotation circuit as well as a simple cleaning of the bulk Cu/Pb concentrate by Pb
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
Lead and copper are routinely separated using two stages of flotation, ie first the copper or lead is recovered to produce a concentrate, then a second stage of flotation to recover the other

Jun 25, 2013· But later we changed our mind. And now we are thinking of making copper sulphate crystals from copper sulphate solution, instead of electrowinning copper from it. Now, our problem is that first we want to economicaly separate tin and lead from this copper dust and then we want to make copper sulphate crystals with the copper dust.
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.

Jan 08, 2018· Separation of tin and lead Now I havent so much to solder and would love to separate the tin and the lead as I would have quite many uses for those metals, provided they are pure (97% would suffice). My metallurgical mileu is lead/antimony and lead/copper/precious metal (gold).
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
The copper–lead–zinc ore found in the Jiama mining area of Tibet has a high mud content, a high degree of oxidation, and complex properties, so it is extremely difficult to separate copper, lead, and zinc using a single flotation technology. Therefore, it is necessary to develop an alternative process to achieve separation of these.

I've seen some good tips here and there, but little in the way of pics, and a number of questions unanswered. We have an outside berm that has been shot into for years and has never (to the best of my knowledge) had any lead salvaged from it. I dug around in it and came up with a few pounds of scrap, but I'd like to go with real gusto and not re-invent the wheel in refining a method.
