The fine crushing-wet preconcentration and grinding experiment is done on lean magnetite ore from Inner Mongolia area in China.

Typomorphic characteristics and ore-forming significance of pyrrhotite in the major Cu-Ni deposits,East Tianshan,Xinjiang;

Survey of Research on Pyrrhotite Flotation Both at Home and Abroad;

Difference in Electrochemical Behavior Between Marmatite and Pyrrhotite in Ca(OH)_2 System;

This paper introduces the components of the magnetite and the application and standard of the magnetite powder in the heavy medium coal washing,and probes into the management and control of the medium consumption in the heavy medium coal washing from three aspects of the quality of medium,the management loss and the technical loss.

When the Fe content in SA cinder from pyrite raw material is as high as to 60%,magnetite powder,additive and the above-mentioned powdered cinder can be mixed into production of oxidized agglomerate for iron production.

0 kg/t of raw coal while magnetite powder losses in tailings from magnetic separation is up to 2.
