Lesson Video: Extracting Iron | Nagwa
Hematite is a naturally occurring form of iron (III) oxide, Fe2O3. And it's about 70 percent iron by mass. What this means is that, with perfect extraction, putting one kilogram of ore in, we should get kilograms or 700 grams of pure iron out. However, it's not quite that simple, so let's look at the details.
