metal extraction process

Aug 21, 2020 · This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis. Details for the extraction of aluminum, copper, iron and titanium are given in separate pages in this section

We believes the value of brand, which originates from not only excellent products and solutions, but also considerate pre-sales & after-sales technical services. After the sales, we will also have a 24-hour online after-sales service team to serve you. please be relief, Our service will make you satisfied.

    processes and procedures in the extraction ofiron

    The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres
