Abstract

An apparatus for processing magnetite iron ore, including an upstream cyclone and a mill for grinding particles, wherein the upstream cyclone is arranged to operate as a splitter by diverting material in an overflow of the upstream cyclone to bypass the mill and by feeding material in an underflow of the upstream cyclone to the mill.

Description

[0001] field of invention [0002] The present invention relates to a method and apparatus for processing magnetite, and more particularly, but not exclusively, to a method of processing magnetite into a form suitable for international shipments with improved cost Effective methods and apparatus for processing magnetite. [0003] Background of the invention [0004] It is known to mine iron ore for the production of steel and the like. Iron ore is one of Australia's most important export products, however the applicant has identified the problem that due to the quality of the iron ore product and in particular the purity of the product by weight (i.e. percent, which is actually iron), some hematite iron ores may have lower desirability and pricing in international markets. [0005] Iron ore is the rock and mineral from which metallic iron can be extracted economically. Iron itself is usually in the form of magnetite (Fe 3 o 4 ,72.4% Fe), hematite (Fe 2 o 3 , 69.9% Fe), g...
