The paper presents a process by which superfine and high tinting pigments of iron oxide series are prepared from green vitriol——a byproduct obtained from titanium white production.

Cuprocopiapite and ferricopiapite found for first time in oxidized zone of Hongshan HS-epithermal Cu-Au deposit,East Tianshan,and their mineralogical characteristics;

1% and 74% respectively, voltaite crystal and solid FeCl_3 have been produced by crystallizing in a lower temperature following the vaporization of the wastewater, with 70% iron and 96.
