• Types of Marine Corrosion | BoatUS

    Iron ore has a chemical composition of two iron atoms bonded with three oxygen atoms. As it is mined out of the ground, it's a brownishred powder useless to us. But by refining, purifying, and smelting, we create iron, which is useful. We can use it as plain iron, or we can process it further and combine it with other elements to get different ...

  • What Is a Smelting Plant? (with pictures)

    An ore is generally defined as a rock, or group of minerals, that has potential economic value. The ore does not contain only the metal of interest. For example, iron ore is a rock that contains iron bound up with other chemical compounds and minerals. Smelting ore is the process of removing the metal of interest from its original rock.

    When iron ore is reduced in solid state by using charcoal, porous iron blocks are formed. Therefore, reduced iron blocks are also called sponge iron blocks. Any useful product can be obtained from this material only after removing the porosity by hot forging. The iron so obtained is termed as wrought iron.

    Nov 01, 1999 · Corrosion in metals is a natural phenomenon. As we excavate iron ore and process the ore into a steel plate or pipe, we add energy to the metal. Since all materials tend to remain at the lowest possible energy state, the energy that we have introduced into the metal is released through the electrochemical reaction of corrosion.

    Workers used pickaxes and pry bars to get the ore out of the ground. After digging the ore, they tried to remove as much waste, including clay and soil, as possible from the ore. One method was to "flat" the ore, or roll castiron, horsedrawn breakers over the ore. In the nineteenth century workers also often washed the ore to separate waste.
