open cast iron ore efficient processes involved

Cast iron. The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesnt shrink much when it solidifies. It is therefore ideal for making castings hence its name. However, it is very impure, containing about 4 of carbon. This carbon makes it very hard, but also very brittle.

What are the main methods of mining American

2 There are four main mining methods underground, open surface pit, placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Cast iron is strong, but it suffers from brittleness due to its carbon content, making it less than ideal for working and shaping. As metallurgists became aware that the high carbon content in iron was central to the problem of brittleness, they experimented with new methods for reducing the carbon content in order to make iron more workable.
