Mineral gems are the most commonly used materials in the steel industry, which are derived directly from the nature that consisting of one or more types of minerals. Mineral rocks are categorized as chemical aspect in four groups as carbonates, sulfates, oxides and silicates.
Amongst the mineral gems, iron ore is the first stone that humankind has long been able to exploit and process in vertical-shaped furnaces by direct heating capable of separating its derivatives, which at that time played a decisive role to victory in wars for human, is one of the most important inventions of mankind. Over time, other uses which has been discovered for iron, leads more identified and extracted it at that time.
Subsequently, with the development of the science and technology of utilizing mineral gems by studying geology, more mineral ores were identified and extracted. Today, hundreds of types of mineral stones, which each one play an important role in various industries, are appeared. Chromium, Manganese ore, Phosphate rock, Copper stone and some other of the most important and most used steel mills are nowadays a major feedstock in the transformation industry, and their pricing is determined on their index base. In this way, Avijeh Co. is trying to identify the mines in Iran and around the world to supplying this basic commodity for other conversion plants.
