The 6 Steps To Modern Steel Production Explained

The 6 Steps To Modern Steel Production Explained

As iron is the main component of steel it firstly needs to be made Iron ore lime and coke are placed into a blast furnace and melted The resulting liquid known as molten iron is then formed As molten iron still contains around 4 – 4 5 impurities such as carbon which in turn make the metal brittle they need to be eradicated.

The IFCON process developed by ISCOR in South Africa is capable of producing steel directly from coal and iron ore 1 In this process coal and ore are added continuously to a channel type induction furnace containing a slag metal bath Electrical energy is supplied by the induction furnace for heating and stirring the bath.

From Ore To Finished Product Copper

From Ore To Finished Product Copper

Copper is a major metal and an essential element used by man It is found in ore deposits around the world It is also the oldest metal known to man and was first discovered and used about 10 000 years ago And as alloyed in bronze (copper tin alloy) about 3000.

Comprehensive Utilization Of Iron And Phosphorus From

Comprehensive Utilization Of Iron And Phosphorus From

Nov 06 2017 An innovative process of coal based reduction followed by magnetic separation and dephosphorization was developed to simultaneously recover iron and phosphorus from one typical high phosphorus refractory iron ore The experimental results showed that the iron minerals in iron ore were reduced to metallic iron during the coal based reduction and the phosphorus was enriched in the metallic iron.
