As the industrial revolution developed, so did the iron industry. A set of innovations, from different materials to new techniques, allowed iron production to expand greatly. In 1709, Darby became the first man to smelt iron with coke (which is made from heating coal). Although this was a key date, the impact was limited — as the iron was ...

The project includes a 522 km, 610 and 660 mm diameter iron ore pipeline, which when complete will be the longest and largest (tonnage) iron concentrate pipeline in the world. Two pump stations have been provided for the pipeline with the provision to add additional pumps later should iron ore transport capacity increase as the mine develops.

An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element (s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore.

Ore genesis theories are dependent on the mineral or commodity. Ore genesis theories generally involve three components: source, transport or conduit, and trap. This also applies to the petroleum industry, which was first to use this methodology. Source is required because metal must come from somewhere, and be liberated by some process.

Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
