A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...
Answer (1 of 2): Theoryotically it is possible to smelt iron ire in a refractory lined vessel with coal or coke. But practically its possible only thru some well established processes. In cupola we cant smelt ore because lining won't withstand smelting temperatures, slag wont flow due to low tem...
When the ore is mined, it is sent for electrolytic processing or smelting. Freeing manganese from the open pit rock bed requires a lot of manpower and time. As you know in this method, the open pit mining using the standardised equipment and methods for overburden are removed to extract the manganese ore.

Pig iron is the intermediate product of smelting iron ore with coke, usually with limestone as a flux. Pig iron has very high carbon content, typically 3.5–4.5%, which makes it very brittle and not useful directly as a material except for limited applications.
The vertical migration of metals through soils and rocks was investigated at five historical lead smelting sites ranging in age between 220 and 1900 years. Core samples were taken through metal-contaminated soils and the underlying strata. Concentration profiles of lead and zinc are presented from which values for the distances and rates of migration have been derived. Slag-rich soil horizons ...
"Manganese ore is converted to fer-romanganese using the electric smelting process, and then used in the production of mild steel -ferromanganese production being a beneficiation process of adding value to the manganese ore itself," he explains. While the cost of electric power and the transport cost of ore to the smelter plant make
