A Method of Determining Recoverable Iron in Mixed

The Davis tube test has been used for many years as a laboratory method for determining the magnetic iron recoverable from a magnetite iron orebody. This paper describes a method for determining the recoverable iron from ores of the Labrador Trough type, with the usual flow sheet utilizing spirals followed by magnetic separation.

Comparison of iron loss calculation methods for soft
