Study on preparation of transparent iron oxide yellow with [Na_2Fe_6(SO_4)_4(OH)_(12)] residue;

New technology of preparing iron oxide yellow from pyrite cinder;

Study on the preparation of iron oxide yellow pigment by dropping method;

Preparation of ferrite yellow from waste acid from making titanium dioxide;

FeSO_4 prepared from pyrite cinder and NaOH were used as raw materials to prepare the α-FeOOH seed,and the ferrite yellow pigment was prepared by dripping NH_3·H_2O in the secondary oxidation process.

A wet air oxidation process has been developed for preparation of ferrite yellow,one of ironbase pigments,from sulfuric acid slag used as raw material and pyrite powder used as reductant.

Effects of Paddle's Types on the Preparation of Ultrafine goethite Particles;

The results indicated that the rheological properties of the reaction slurry were mainly determined by formation mechanism and morphology of goethite.

The effects of doping time and silicon content on the particle morphology and structure of goethite were studied in detail, and ultrafine α FeOOH particles with average length at 0.

The study on the preparation of iron yellow from pyrite cinders;

The technological process for the preparation of iron yellow from iron sulfide slag by sulfate oxidation method is described.

The difference from the traditional technology which used acid method to prepare ferric yellow pigments,we use NH3-H2O as precipitating agent replacing NaOH to prepare a -FeOOH seed, and in secondary oxi.

Thermodynamic and kinetic analysis on the In & Zn solvent extraction,ferric yellow preparation and alkaline decomposition of jarosite residue was systematically carried out,respectively.
