I believe it is Magnetite. But, Haemetite is more economical, hence for Industrial Purposes, it is more widely used.

What is the density of iron ore?

The density of iron ore is variable. Iron ore refers to a rocktype that contains iron minerals. The type and concentration of the iron minerals as well the type and concentration of non-iron minerals determines the density of the iron ore. Typical high grade iron ore is approximately 65% hematite and 35% other (commonly silicate). The density of hematite is approximately 5 g/cc and a general density for crustal rocks (silicates) is approximately 2.67 g/cc. Therefore iron ore that is 65% hematite and 35% silicate would have a density of approximately 4 g/cc.


What does iron ore feel like?

Iron ore typically feels heavy, dense, and often gritty or coarse due to the presence of mineral particles. It can vary in texture depending on its composition and any impurities present in the ore. Some types of iron ore may also feel slightly magnetic due to their iron content.


How much does one cubic yard of iron ore weigh?

One cubic yard of iron ore typically weighs about 2.5 to 3 tons.


How does iron in the past work?

In the past, iron was smelted from iron ore in furnaces fueled by charcoal or coke. The iron ore was heated to high temperatures to remove impurities and extract the iron metal, which was then shaped into various tools, weapons, and objects through forging or casting methods. The discovery and mastery of ironworking techniques revolutionized ancient societies by providing stronger and more versatile metal tools and materials.


How much energy is used to mine 1 ton of iron ore?

The energy used to mine 1 ton of iron ore can vary depending on the method and location of mining operations. Generally, it takes around 25-30 megajoules of energy per ton of iron ore produced. This includes energy used in drilling, blasting, hauling, and processing the ore.
