4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

The minerals that make up the iron mining tailings would express more charges if they were clay-sized, mostly (Jordão et al., 2021). Microbial biomass carbon (MCB) is a vital component of active soil organic matter, encompassing bacteria, fungi, and protozoa, typically constituting 2–5% of total organic carbon and 1–5% of total soil nitrogen.
