smelting galena silver ore - johannsoutdoor.nl. Galena can also be used in alloy reactions requiring silver-bearing ore Because these reactions treat the galena nugget as the equivalent of 4 silver bars, the resulting alloy will show a roughly 30% increase in value over smelting the galena separately Galena is also magma-safe, but just barely Since galena is a mid-value ore, however, you .

what are some easy ways to melt galena? - Instructables

You aren't going to extract the silver just by melting, you need to smelt it. Pack it with charcoal in a ceramic crucible with a lid on, and blast it with your gas torch for several minutes. Don't uncover the mixture while it is hot.

Evolution of Silver-smelting Technology of Japan in

Beside argentiferous galena ores, silver sulfide ores are another kind of silver sources. In order to smelt silver sulfide ores an addition of lead (metal, galena or litharge) is neccesary. Lead collects silver effectively in the molten state during smelting. Silver is extracted from the resulted argentiferous lead using cupellation.

Galena Mineral Uses and Properties

Argentiferous galena: Argentiferous galena from Coeur d'Alene, Idaho. Specimen is approximately 2-1/2 inches (6.4 centimeters) across. Argentiferous galena has a silver content that is often high enough for the galena to be mined as an ore of silver. Some galena mines receive more revenue from their silver than from their lead production.
