Introduction

Magnetite is recovered as a by-product of the copper operations. Since operations commenced in 1965, Magnetite has been separately stockpiled onsite.



Safety Data sheet

Magnetite - material safety

Chemical composition

Fe3O4

Scope

The Specifications cover the following two magnetite products:
  • Dense media separation (DMS) - medium grade; and
  • Iron ore (coarse grade)

Manufacture

Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. 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 66% Fe (greater than 95% magnetite). This upgraded magnetite is then subjected to elutriation, to generate medium and coarse grade products. The medium grade is the DMS product and the coarse grade is sold as a blend feed to iron- and steelmaking customers.
