The company has its own ilmenite mine in Hauge i Dalane/Norway, a key raw material in the sulphate process. KRONOS is certified to DIN EN ISO 9001, DIN EN ISO 14001, DIN EN ISO 50001 and FSSC 22000. There are two processes for manufacturing TiO 2 pigments, one uses sulphuric acid for digestion (sulphate process), while the other uses chlorine (chloride process). KRONOS plants employ both ...
"The sulphate ilmenite market has rebounded fast, we've seen an increase from 80 up to 120 to China," one source said. Producers attributed the increase in prices to higher activity in TiO 2 and rationalisation of the Chinese industry, as well as tighter ilmenite supply owing to lower iron ore prices. Sulphide ilmenite is produced as a byproduct of magnetite, the mining of which takes ...

01/01/2020 · Based on cost effectiveness and generation of relatively less waste, the chloride process is considered more profitable than traditional sulphate process. The requirements for highgrade rutile is, however a major drawback. The use of concentrated sulphuric acid at temperatures of 150200 °C is preferred for the sulphate process as dissolution of ilmenite significantly affected by both ...
Abu Ghalaga Ilmenite Ore Upgrading Helals. As Abu Ghalaga ilmenite ore is analogous when smelted to the Canadian ilmenite ore, produced from the mines of Quebec Iron and Titanium QIT Inc., which is beneficiated and smelted at Sorel TracyQuebec, to produce titania slag with 80 mass percent TiO2, representing an important feedstock for the manufacture of TiO2 pigment by sulphate process.
keywords: titanium slag, synthetic rutile, chloride process, sulfate process, acid leaching, TiO 2 pigment 1. Introduction Titanium is relatively abundant in the earth's crust, which is usually found in igneous and metamorphic rocks as ilmenite (FeTiO 3), rutile (TiO 2) and titanomagnetite (Fe 2 TiO 4–Fe 2 O 4). A survey on the use of titanium in its various forms indies that almost 95% ...
It is sold primarily to pigment producers that use the sulphate process. SORELSLAG® provides these customers with an environmentally friendly way of minimising waste generation. We are the world's leading supplier of highgrade feedstock for titanium pigment producers that use the sulphate process. UGS™ is an upgraded slag, with a titanium dioxide content of approximately 95%. It is sold ...
12/07/2018 · TiO2 is produced from ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lowergrade, cheaper ores. It generally has higher production costs and with acid treatment is more expensive to build that a chloride plant. .

The sulphate process is performed through hydrometallurgical route and uses ilmenite ores or low grade titanium slag (72 87% TiO . sulfate process translation French EnglishFrench dictionary . The invention relates to a process for ...
Ilmenite is converted into titanium dioxide via the sulphate process. Sulphate process plants must utilise lowvanadium ilmenite, as vanadium is a penalty element. Titanium dioxide pigment can also be produced from higher titanium feedstocks such as rutile and leucoxene via a chloride acid process. Raw ilmenite is refined by decreasing the iron content. Carbon is used to convert some of the ...

01/11/2012 · Economic production of titanium dioxide (yield >98 %) from ilmenite has been achieved by use of a modified sulfate reduction process. A series of samples were prepared by varying the concentration of titanium dioxide nuclei (,, and %) and further impregnation with antimony and vanadia. The structural and acidic properties of the samples were comprehensively studied by Xray ...
from ilmenite ores. These are sulphate, alkaline and chloride based. However, the HCl treatment route was chosen for this study. This process exhibits fast kinetics, excellent impurities removal and the potential to regenerate the acid makes it sustainable and environmentally friendly. Samples of the ore screened to a 106 – 212 µm size fraction were treated with 700 mL of 18% ( M) HCl ...
These processes require different quality TiO 2bearing mineral feedstocks that are described as either sulphate feedstock or chloride feedstock. The main raw materials for the sulphate process are sulphate ilmenite (4854% TiO 2) and sulphate slag (7682% TiO 2).

12/08/2020 · The MUD used in this study came from a European TiO2 factory, which uses the sulphate method in its production process. The raw material used in the production of TiO2 is a mixture of ilmenite and ilmenite slag. The ilmenite came from a deposit near Tellnes, Norway. The content and morphology of this deposit is well known and described widely in the literature [35,36]. It contains .
