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.Operations at Mining Area C focus on enriched areas of both the Brockman and Marra Mamba Iron Formations, for mining purposes the area has been sub-divided into a series of deposits.

MINING AND PROCESSING Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.Miners lamps used in areas where iron ore is excavated and processed can be tested to either AS NZS 62013.1 2001, Caplights for use in mines susceptible to firedamp - General requirements - Construction and testing in relation to the risk of explosion and AS NZS 62013.2 2001, Caplights for use in mines.Christmas Creek Iron Ore Mine.
