Titanium purification process . United States Patent 3929962 is performed upon ilmenite ore wherein said ore is beneficiated by reducing its iron content to metallic iron and leaching said metallic iron with ferric chloride solution. This dissolved portion of Ti 2 O 3 will later become the major part of the pure TiO 2 pigment product.

Iron: From mythical to mundane Roots of Progress

2019-10-22  Metalworking is one of the oldest crafts, going back far beyond recorded history. But until a few thousand years ago, one of the most abundant metals—iron—was virtually unknown. The ancient Egyptians and Sumerians knew iron only from meteors, and considered it heavenly, a gift from the gods. Later civilizations discovered how to smelt it, and their period came to be known as the Iron Age

Primary Metal Production Chemical Engineering

2009-12-4  Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.

2015-7-26  The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via the Contact Process. Much like in the Blast Furnace, the calcium carbonate is involved in the production of the slag.

Iron (Fe) and water Water Treatment and Purification

Iron is essential for nitrogen binding and nitrate reduction, and it may be a limiting factor for phytoplankton growth. Solubility in salt water is extremely low. The iron cycle means reduction of tertiary iron by organic ligands (a process that is photo catalysed in surface waters), and oxidation of binary iron.
