What mining methods are used in Australia?

The mining method in Australia typically involves blasting and removing surface layers of soil and rock to reach the coal seam. When the coal seam becomes exposed, it is drilled, fractured and the coal excavated for processing. Processing can be dependent on the cleanliness and quality of the coal mined.

What method is used to mine iron?

Surface mining
Surface mining is exactly what the word says – digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining.

What type of iron ore is mined in Australia?

hematite
Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s. Approximately 96% of Australia’s iron ore exports are high-grade hematite, the bulk of which has been mined from deposits in the Hamersley province of Western Australia.

How is iron ore mined today?

For the past 50 years, more than 90 percent of US iron ore production has been mined from the Lake Superior deposits. None of the iron ore now mined in the US is “direct shipping” ore ready to be fed into the iron- and steel-making process. All the iron ore currently mined is from open pits.
