Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage. This results in the upgrading of magnetite to 62.5% Fe (greater than 90% magnetite). This upgraded magnetite is then subjected to elutriation, to generate the DMS magnetite product.
Ironveld Mining has agreed to form a joint venture (JV) with Pace, a mining and industrial supply chain solutions provider, to produce and sell dense media separation- (DMS-) grade magnetite from the former's mine in Limpopo, South Africa.. Under the JV agreement, the duo will launch an equally-owned newly incorporated company, which …
From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. Transportation The taconite pieces are scooped up by electric shovels. Each...

Magnetised drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The lighter particles that were separated during the spiral gravity separation step are rolled into balls (combined with bentonite or a similar binding agent) and cooked in an induction oven. This process is known as pelletisation.
