Iron ore has been used by man for over 3,000 years. The first iron ore deposits in Australia were found in 1880. By early 1900s small scale mining had begun. However, it wasn’t until the early 1960s that new processes and the advent of efficient heavy rail haulage allowed for larger scale iron ore extraction in the Pilbara as world demand ...
The Hope Downs iron ore mine is situated 100km north west of Newman in the province of Pilbara, Australia. The mine is owned jointly by Hancock Prospecting (50%) and Rio Tinto (50%). About #36;1.6bn was approved by Rio Tinto in August 2010 for the development of Hope Downs 4 and connecting it to the existing rail, power and port infrastructure.
Sintering is a process used to agglomerate iron ore fines in preparation for blast-furnace smelting and is usually carried out at iron and steelmaking centres. It involves the incorporation of crushed limestone, coke and other additives available from iron and steelmaking operations. These additives include wastes extracted from furnace
Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting.
