Products Made from Iron OreCSR101

Products made from iron ore. Iron ore is a mineral substance heavily comprised of iron oxides primarily hematite (Fe203) and magnetite (Fe304). While mostly unusable in its native form when mixed with a reductant and heated it produces metallic iron (Fe).

How gold is madeHow Products Are Made

Gold recognizable by its yellowish cast is one of the oldest metals used by humans. As far back as the Neolithic period humans have collected gold from stream beds and the actual mining of gold can be traced as far back as 3500 B.C. when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry religious artifacts and utensils such as goblets.

Gold History of Use Mining Prospecting Assay Production

Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia a mixture of hydrochloric and nitric acids and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.
