Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.

How to Take the Impurities out of Gold | LEAFtv

The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore. Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away.

How Is Lead Mined? | Reference.com

Lead is commonly found in deposits with other minerals, such as silver, zinc or copper. Once the lead ore is brought to the surface, it goes through a series of refining processes that separate out the different metals contained in the ore. For example, U.S. mines in Alaska and Missouri are zinc and lead …

Lead processing - Refining | Britannica.com

Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy.
