How electroplating works Explain that Stuff

All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead. Electroplating is very similar to electrolysis using electricity to split up a chemical solution, which is the reverse of the process by which batteries produce electric currents.

Investigating the sustainability of the global silver

Investigating the sustainability of the global silver

Silver has been manufactured by humans since at least 3000 BC, first from ores with native silver and later from lead ores. After gold and copper, silver was the third metal for humans to find and work. In modern times, silver is supplied in significant amounts from mining of zinc, lead and copper. 1.1.
