Based on the research work previously, a new technology of continuous prereduction of fine iron ore with hydrogen at low temperatures (180~570℃) and low pressure (<0.

Pre-reduction of fine iron ore at low temperatures was studied with single factor and orthogonal experiments.

Self-intensity of binding phase in iron ores during sintering;

Fluidity of liquid phase in iron ores during sintering;

Evaluation on liquid phase fluidity of iron ore in sintering;

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.

Physical and chemical properties of iron ore powder and carbon powder with mechanical impact are studied.

Energy storing mechanism and thermodynamics of reduction of mechanically milled iron ore powder were studied.

A series of friction and wear tests were performed on an MG-200 high temperature and high speed test rig to investigate the effect of barite and iron ore powder doped in the drilling mud on the friction and wear behavior of a casing/drill-pipe pair.

Temperature-rising characteristic of chromite ore fines containing coal in a microwave field;
