Steps For Firing/Smelting. Mix the ore, wheat flour lard and ½ of the soda ash. Put ½ of the silicon sand in the bottom of the crucible and add the ore mixture. Cover the ore mixture with the remaining soda ash, the borax and the silicon sand. Place in the furnace and put on high heat

Silver is extracted from lead ores in large furnaces, a process called cupellation. Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century. In this process, crushed ore is placed in a bath. Air bubbles are blown through the mixture to carry the silver to the top of the bath where it forms froth. The silver-rich froth is skimmed from the bath and smelted so that it can
Silver has been known since ancient times. Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC. The silver mines at Laurium were very rich and helped provide a currency for the economy of ancient Athens, where the process involved mining the ore in underground galleries, washing and then smeltingit to produce the metal. Elaborate washing tables still exist at the sit

Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 o C (1764 o F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes. Ore treatment by mercury amalgamation, such as in the patio process or

Silver is extracted from the ore by a smelting or leaching procedure. Here's how to identify silver ore. Find an area that has produced silver ore in the past. The best place to begin looking is an established geologic region whose environment was favorable to ancient silver deposits. Look for deposits of lead. Lead usually contains traces of silver and can be a guide to identifying more
