Metal Profile Iron Properties and Characteristics

Jun 25, 2019 · Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.

Limestone Facts

Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms.
