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 ...

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 ...

These material screening devices prevent oversize muck from entering the ore pass. The most common types of these screens are grizzlies and scalpers, although scalpers tend to experience greater amounts of oversize blocks wedging between bars, resulting in higher maintenance costs. In the use of scalpers, it is common for operating crews to push the oversize through the scalper, this practice ...
