Anexperimental studyof iron-smelting

Essentials ofPrehistoric Iron Smelting The production ofiron from an ore seems to bea simple reduction process: the iron oxide of the ore (Fe203) is reduced to elemental iron by the carbon monoxide (CO)produced by the burning ofcharcoal (Fe203+3CO~2Fe+3CO2). However, there are several difficulties inthis process: one isthe tendency ofthe

Crushing slag

I'm not a processing guy, but I believe that when coming out of the smelter, the slag is in molten liquid form and is essentially poured onto the slag piles. This is a cool sight to see especially at night. There is no need for slag coming out of the smelter to be crushed.

Optimization of the flotation of copper smelter slags from …

Slag cleaning is the process of removing wanted minerals and metals from the slag. Slag cleaning can be divided into two types; the first is pyrometallurgical reduction and settling, performed in a slag-cleaning furnace, the second is minerals processing of solidified slag, including crushing, grinding and froth flotation (Davenport et al., 2002).

Iron processing | Definition, History, Steps, Uses, & Facts

Although the Romans built furnaces with a pit into which slag could be run off, little change in iron-making methods occurred until medieval times. By the 15th century, many bloomeries used low shaft furnaces with water power to drive the bellows, and the bloom, which might weigh over 100 kilograms, was extracted through the top of the shaft. The final version of this kind of bloomery …
