extraction of iron from iron sulphide

Processes and Procedures in the Extraction of Iron

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.get price

Iron Sulfide an overview ScienceDirect Topics

Pyrite (FeS 2) and other iron sulfides are often present in significant quantities in many sedimentary deposits, including those associated with coal and commercially important metal ores. When sedimentary deposits containing large quantities of sulfide minerals are exposed to air and water, they rapidly oxidize to produce iron and other metals, sulfate, and acid.get price
