Research Project

Project/Area Number	15J03055
Research Institution	Tohoku University
Principal Investigator	樊涌東北大学, 多元物質科学研究所, 特別研究員(PD)
Project Period (FY)	2015-04-24 – 2017-03-31
Keywords	molten oxidation / copper slag / 1 vol% / HV pulse voltage
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.
