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.

磁铁矿和赤铁矿的结晶行为表现出一种权衡关系。较低的氧分压有利于磁铁矿的沉淀。采用高压电脉冲解离技术对铜渣中的沉淀磁铁矿进行了解离试验，研究了高压电脉冲解离铜渣中沉淀磁铁矿的机理。
