sulfate process in ilmenite

Combined production of synthetic rutile in the sulfate ...

2017-5-25  This paper describes a novel process for preparation of synthetic rutile using an intermediate, sulfated ilmenite from the sulfate TiO2 process as the feedstock. The synthetic rutile can be obtained by selective thermal decomposition of the sulfated ilmenite, followed by targeted leaching for removal of various impurities.

Ilmenite - an overview ScienceDirect Topics

In the sulfate process, ilmenite or slag is attacked with sulfuric acid to give soluble sulfates. Controlled hydrolysis of the titanyl sulfate leads to precipitation of a hydrous oxide which is then calcined. Elements such as aluminum, zinc, potassium and phosphorus are added at calcination to control crystal growth and to determine whether the ...

SULFATE PROCESS Meide Group USA Inc.

Sulfate process is one of the processes for producing Titanium Dioxide (Anatase and Rutile). For sulfate process, ilmenite (FeTiO3) has been used as a feedstock material. The inlet stream is reacted with concentrated sulfuric acid (H2SO4) to extract the converted Titanium Oxygen Sulfate (TiOSO4).

Application Note Titanium Dioxide - Sulfate Process

2020-6-18  The sulfate process relies on sulfuric acid (H2SO4) to leach titanium from ilmenite ore (FeTiO 3). The resulting reaction produces titanyl sulfate (TiOSO 4). A secondary hydroly-sis stage is used to break the titanyl sulfate into hydrated TiO and H2SO 4.2 Finally, heat is used to remove the water and create the end product - pure TiO
