Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core.It is the fourth most common

An iron content of just 12 to 15% in olivines creates the ideal peridot color, whereas higher levels create a “muddier” brown color. Thus, olivines closer in composition to the forsterite end tend to be greener. In contrast, those closer to iron-dominant fayalite tend to be yellower and browner.

An axe is a tool mainly used to hasten the breaking of wood-based blocks, remove the surface layer of certain blocks, and as a melee weapon.

In this process chemicals are added to a fine-particle mineral mix resulting in one mineral being flocculated and the remaining minerals being dispersed in a water slurry. Flocculation technologies are used in the iron-ore industry to flocculate and recover iron oxide and in the clay industry to flocculate the quartz and reject grit.

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.
