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.
Fiji's largest island, Viti Levu, has recently become the site of the first ever black sand mining operation in Fiji, with another in the exploration phase. Black sand mining involves extracting magnetite or the iron ore content from mineral sands through the excavation of the sea floor, beaches or dunes.

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting – The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of …
2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as …
