Figure 10 a shows the variation in iron grade and iron recovery with exposure time. The iron grade increases from feed grade of 50.6% to a maximum of 61% for microwave exposure of 10 min. The iron grade of the concentrate increases significantly at lower exposure time; however, at increased time duration, the iron grade saturates ~ 61% Fe.

Beginning in the mid-1800s, iron manufacturers discovered that adding chromium to steel produced a harder, more useful metal. Steel is a mixture of iron with a small amount of carbon - around 1 percent. Such mixtures of metals are called alloys. Iron, in its pure form, can be heated and then bent, hammered or "wrought" into many forms.
