— When iron ore is melted and cast into molds, this manufactures durable cast iron parts for heavy machinery, pipes, engines, and industrial uses requiring vibration damping. Cast iron's low melting point makes it ideal for casting complex shapes, though it is less malleable than other ferrous metals.
— Wrought iron is quite soft and easily worked and has little structural strength. It was once used to make decorative gates and railings, but these days mild steel is normally used instead. Mild steel: Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron.
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
