Step 1: Cargo preparation. In the steel industry, the raw material for steel production is iron ore. And in the first stage of the production process for this material, iron ore is agglomerated using lime and coke fines. At the end of this step, the resulting product is called sinter. The charcoal used is processed in the coke oven plant and ...

These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like ...

The openings made in the process of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping, so that every effort ...

Crushing and screening are crucial steps in the process of open pit mining for iron. Once the ore has been blasted and drilled, it needs to be broken down into smaller pieces before it can be transported for further processing. The first step is crushing, where large chunks of ore are fed into a crusher and reduced to smaller particles.
