Large iron ore resources occur in the Roper iron field, hosted in the Roper Group of the McArthur Basin, south of the Roper River. The field contains more than 1 billion tonnes of moderate grade iron ore, with around 85 million tonnes of higher grade direct shipping ore (57-59% Fe) at the Roper Valley and Roper Bar deposits.

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.

IRON MINING TODAY Open pit mining for iron ore replaced shaft mining very early on in the history of the Michigan Iron Ranges. Today, all the underground mines are closed, and only a very few open pit mines are still operating. What remains of the underground mines is often only a few heaps of waste rocks (below) and some slumped landscapes.

Mining and processing: Iron ore is typically mined through open-pit or underground mining methods, depending on the depth and location of the deposit. After extraction, iron ore is processed to remove impurities and obtain the desired iron content through crushing, grinding, magnetic separation, and other beneficiation techniques.

Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a ...
