| Outline of Annual Research Achievements |
The crystallization behaviors of the magnetite and hematite showing a trade-off relationship. A lower oxygen partial pressure was beneficial to the precipitation of magnetite. In particular, the use of 1 vol% oxygen resulted in a selective oxidation tendency for magnetite precipitation.
A new specific mineral liberation technology - High-voltage (HV) electrical pulses was implemented for an attempt to the liberation of precipitated magnetite in copper slag, which capable of producing of the high percentage of the monomineral particles at disintegration of mineral aggregates.
