Extraction of Iron Class 12, General Principles and

May 15, 2020 In order to convert cast iron into wrought iron, the percentage of carbon and that of other impurities has to be decreased. This is done by heating the cast iron on the hearth of a reverberatory furnace (known as puddling furnace) with haematite.

Blast furnace Wikipedia

The hot carbon monoxide is the reducing agent for the iron ore and reacts with the iron oxide to produce molten iron and carbon dioxide. Depending on the temperature in the different parts of the furnace (warmest at the bottom) the iron is reduced in several steps.

Iron Making Boundless World History

Puddling produced structural-grade iron at a relatively low cost. It was a means of decarburizing pig iron by slow oxidation, with iron ore as the oxygen source, as the iron was manually stirred using a long rod. Puddling was done in a reverberatory furnace, allowing coal or coke to be used as fuel.

How to Separate Gold from Pyrite

Mar 17, 2017 When the ore was dehydrated by roasting in reverberatory furnaces the extremely fine particles of gold were agglomerated, and between 80 and 90 per cent, could then be extracted by amalgamation, the remainder being presumably coated by oxides of iron. The richness of the ore, however, made even this result unsatisfactory, and a process of
