steel mining process steps

Smelting is a process of applying heat to ore in order to extract a base metal It is a form of extractive metallurgy It is used to extract many metals from their ores, including silver, iron, copper, and other base metals Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind

Coal Mining and Processing Mining the Coal Coal miners use giant machines to remove coal from the ground They use two methods: surface or underground mining Many U S coal beds are very near the grounds surface, and about two thirds of coal production comes from surface mines Modern mining methods allow us to easily reach most of our

As the worlds leading steel and mining company, our business operations extend from the mining of iron ore and coal to the production of the full range of steel products and services In 2016, we produced 55 2 million tonnes of iron ore and 6 9 million tonnes of coking coal, a form of carbonised coal burned in blast furnaces to melt iron

Jun 22, 2018 In order to even begin work, mining rights must be acquired, access roads must be constructed to help workers navigate the site, and a power source must be established Production Once these elements are obtained, the physical mining processor, the first step of productionbegins The mining process can be broken down into two categories:

Aug 18, 2015 Mining operations are complex They aren't your run of the mill type projects These billion dollar complexes consist of various interconnected projects, operating simultaneously to deliver refined commodities like gold, silver, coal and iron ore Its a five stage process and weve broken it down using GIFs Exploration

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes, which will ultimately be made into products for everyday use The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver This process removes 93 of the gold and 70 of the silver
