METHOD OF RECOVERING IRON FROM ZINC SULPHATE

1. A method of recovering iron from a zinc sulfate solution produced by a leaching process in which zinc ore is dissolved in sulfuric acid, the method comprising: a conditioning process including a step of reducing a conditioning process input solution, which is the zinc sulfate solution; and an iron precipitation process for recovering iron as hematite, including a step of pressurizing and

GCSE CHEMISTRY Extraction of Iron Haematite

2017-3-27  Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.

Processes and Procedures in the Extraction of Iron

2021-2-15  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.
