Interview Questions and Answers

The chemical composition of iron ore varies depending on the type of ore and its source.

• Iron ore is primarily composed of iron oxides, such as hematite and magnetite.

• Other elements present in iron ore include silica, alumina, phosphorus, sulfur, and trace amounts of various metals.

• The specific chemical composition of iron ore can vary widely, even within the same deposit or mine.

• For example, a typical chemical composition of iron ore may include around 60-70% iron, 2-6% silic...read more

Various types of explosives are used in blasting operations, such as dynamite, ANFO, and emulsion explosives.

• Dynamite is a commonly used explosive in blasting due to its stability and ease of use.

• ANFO (ammonium nitrate fuel oil) is another popular explosive choice for blasting operations.

• Emulsion explosives are also used in blasting for their water resistance and high energy output.

The wide base of a steel light pole provides stability and support to the pole.

• Prevents the pole from toppling over in high winds or other extreme weather conditions

• Distributes the weight of the pole and the light fixture evenly

• Allows for easy installation and maintenance of the pole

• May include anchor bolts or other reinforcement to further enhance stability

Iron ore is a mineral substance which, when heated in the presence of a reductant, yields metallic iron (Fe).

• Iron ore is typically composed of iron oxides and may contain varying amounts of other minerals such as silicon, aluminum, and phosphorus.

• The chemical composition of iron ore varies depending on the type of ore and the mining location.

• Hematite and magnetite are the two most common types of iron ore, with the former being more commonly mined due to its higher iron conte...read more
