Manganese - USGS

Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.

Mar 13, 2020  Location. Ohio, USA. Mar 13, 2020. #4. The question is why you want to refine coins. They are what is known as "self assaying". Anyone who knows anything about coins will know they are 35% silver. Once you refine them, no matter how good of a job you do, you have an unknown metal. Sometimes it is just better to keep things like coins as they are.
