Evolution of Blast Furnace Iron Making. The origin of the first smelting of iron is concealed in the unrecorded history of human civilization. The first evidence of iron implements being used in ancient times actually comes from Egypt where an iron tool was found in a joint between two stones in a pyramid.

How copper is made

How copper is made

+

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

How do we extract iron from its mineral ores? How do we convert it into steel? The raw materials needed limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described.

Lateritic nickel ore deposits

Lateritic nickel ore deposits

+

Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel.
