A washing section is a "must" in all operations handling wet, sticky ore. This facilitates ore handling, crushing, and also affords a means for separation of primary slimes and increasing grinding capacity. These slimes usually contain the bulk of the soluble salts and in many cases this fraction should be treated separately or even ...

Stoping is a method of extracting ore from an underground mine that leaves behind an open space called a stope. Stoping is the method and the stope is the physical open space that was dug out into a tunnel or room in the mine. Stopes are created to provide direct access to the ore body. Welldesigned stopes are vital for the underground mining ...

Once you have some Iron Ore, smelt in at the Furnace and you'll learn the Anvil recipe. Return to the Workbench and craft an Anvil using 5 Iron Bars and 15 Rocks. Before you can make a Sword at the Anvil, you'll need to make a Steel Axe and chop down some Birch Trees. Then, you'll be able to craft a Sword using 7 Iron Bars and 5 Birch Wood.

In the integrated steelmaking route, iron ore containing ferrous oxides is converted to metallic iron inside the blast furnace via a chemical process called 'reduction'. Coal in the form of metallurgical coal and pulverised coal act as the active agents or 'reductants' that strip away oxygen from the iron ore to yield metallic iron ...
