Liquation
Liquation requires that the silverrich copper first be melted with approximately three times its weight in lead; as silver has a greater affinity with lead, most of the silver would end up within this rather than the copper If the copper is assayed and found to contain too little silver for liquation to be financially viable (around 031% is the minimum required, ) it is melted and allowed to settle so that much of the silver sinks towards the bottom The ‘tops’ are then drawn off and used to prodThis technique is used to separate an insoluble solid from a liquid It can be used to obtain a product that is free from unreacted chemicals, byproducts or solvent Separating Separation techniques Separating mixtures BBC Bitesize

An environmentallyfriendly method to recover silver, copper and lead
Introduction Copper anode slime is a byproduct obtained during the electrolytic refining of blister copper, and is an important secondary resource for recovering valuable metals such as selenium, copper, silver, lead, tellurium, bismuth, antimony, nickel, arsenic and minute quantities of platinum group metals (Hait et al, 2009, Cooper, 1990, The final separation of this translated mixture was achieved by treatment with nitric acid till saturation of the alkali, whereby the silica (Kiesel) was precipitated and the alkali naturally became “a true saltpeter” for example, lead and copper Figure 3 Open in figure viewer PowerPoint C G Kratzenstein 40 and J D Cappel 35aThe Alchemist, Metal‐Divider and Transmuter Carl F Wenzel and

The Extraction of Copper Chemistry LibreTexts
Copper can be extracted from nonsulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper (II) sulfate solution Concentration of the copper (II) sulfate solution by solvent extractionA mixture solution of calcium chloride and sodium chloride solutions can be separated by adding a solution of sodium carbonate just enough to precipitate calcium as insoluble calcium carbonate Both Cacl2 and Na2CO3 are soluble in water and dissociated completely to ions The calcium will precipitate in a white precipitate as CaCO3 because:Separate pure substances from mixtures University of
