Hematite To Iron Process
Hematite – To Fake or Not to Fake | Appealing Environments
· Hematite is often referred to as a bloodstream purifier. When you polish or drill into this stone, it appears to bleed due to the high concentration of Iron Ore. This stone energizes the entire body by improving circulation and the flow of oxygen to all cells. Hematite is also a protective stone and enhances optimism, courage and willpower.

How Is Iron Extracted From the Earth?
· Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

How is Iron Refined from Ore? (with pictures)
Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
How to Smelt Iron: The 6 Steps to Iron Smelting | The ...
What is iron ore? Iron ores are rocks and minerals rich in iron oxide that can produce metallic iron when smelted. Due to the nature of the iron oxide present in iron ore, they can range in color from dark grey to a deep red. The iron in such ores is commonly found in the form of magnetite, hematite, goethite, limonite, and siderite.

Massive hematite ore (MHO) is a special highgrade iron ore used as lump ore in the process of obtaining direct reduced iron (DRI). The influence of porosity on the reducibility was investigated using optical and scanning electron microscopes. Hematite is the main component of the samples and occurs as granular crystals (10 m), microplates (1 m) and euhedral martite (10 to 30 m).
