∙ 7y agoIron ore can be processed to an intermediate form that we call pig iron. It's a lot more pure than iron ore but not usually ready for use and needs further processing to become a useful metal. Typically it ranges from a little more than 3% carbon to a little less than 5% carbon. It also usually has a fair amount of silica and dross left in it too. Since it is intended as feed stock to furnaces for further processing the exact amounts of the contaminants is not that critical - they get mostly removed during the additional processing.
Cast iron generally has less carbon, silica, and dross left in it after processing. 1.8-4 wt% carbon and 1-3 wt% silicon (with the rest iron) are typical.

Why is there an Iron chloride impurity in chromatography experiment?
The water used to dilute HCL may contain Iron chloride as an impurity so the solution you prepare as a mobile phase is contaminated with iron chloride.
What is the difference between iron and magnet?
Magnet attract things made of iron nickel steel
What is better cast aluminum or wrought iron?
Cast iron, wrought iron and steel are all essentially alloys of iron and carbon.Wrought iron is iron with a low carbon content, it was used in place of Cast iron is iron that has been shaped by being poured into a cast.
How can you tell the difference between a bar of iron a bar of copper and a magnet?
Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
What is one difference between water and iron?
Water (H2O) is a chemical compound and iron (Fe) is a chemical element.
The properties difference between mild-steel and cast-iron?
Cast iron is more brittle then mild steel
What is the difference between a normal skillet and a cast iron skillet?
It depends on what you want to do with the skillet. A deep cast iron pot is idea for deep frying, while a more shallow skillet is best for frying or baking.
What is the difference between white cast iron and nodular cast iron?
Production method is different. Cold rolling method and different.
The main difference between cast-iron and steel?
Steel is an alloy of carbon and iron. If the percentage of carbon is more than 2% then it is called cast iron.
What is the weight difference between cast iron and aluminum 454 heads?
about a 75 # weight difference between both sides.
What is the difference between cast iron ans steel?
aren't they the same thing
How many types of iron and their compositions?
pig iron or cast iron having 4.5% carbon as an impurity wroght iron having 0.15% of carbon steel having 1% carbon
Why is there an Iron chloride impurity in chromatography experiment?
The water used to dilute HCL may contain Iron chloride as an impurity so the solution you prepare as a mobile phase is contaminated with iron chloride.
How are amethyst and quatz different?
Amethyst is quartz that contains an impurity that imparts the purple color. The impurity in amethyst is iron.
Difference between cast iron and mild steel?
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
What is the difference between an slide gate and a sluice gate valve?
The difference is that a sluice gate is made out of cast iron while a slide gate isn't.
What is an impurity found in the iron produced in the blast furnance?
Slag
