Materials flow sheet for ilmenite processing. limitation. This method only considers weighting for climatechange category but it is a key feature for LCA analysis. Moreover, the ILCD method is a more robust and complete method and is a combination of CML, ReCiPe, IPCC, and EcoTox methods. In the second step, cumulative energy demand method is ...
Although ilmenite and rutile are extensively used to extract TiO2 at the industrial level, through the sulphate and chloride processes, they can also be recognized to possess the potential to be...
The proposed method in the present study is potentially more economically viable than the current commercial process that uses HCl for the ilmenite leaching, namely the Benelite process.
A new method of altered ilmenite processing has been studied. In this method, sulfuric acid is used as the reaction medium of the process, and fluoride ions are activators of the dissolving process of the rutile part of the ore raw material. The regression model of the sulfate–fluoride leaching process was developed and analyzed by using the response surface …
4. Electric-separation method is mainly to deal with the coarse concentrate containing titanium pyroxene and other non-conductive impurities produced by gravity separation and magnetic separation. It is widely used in the selection process, and the electro-separation method has requirements on the particle size of ilmenite. The lower limit is 0.04mm, and …
ICC - Process Schematic Text:
The process under analysis comprises three major sections: (1) Ilmenite Processing; (2) Titanium Dioxide Hydration; and (3) Titanium Dioxide Treatment.
The methods consist of heating and fluorination of rutile or ilmenite in a mixture with ammonium fluoride or bifluoride, followed by sublimation of titanium fluoride compounds, …
Here, a systematic review of reported technologies for ilmenite mineral processing is conducted in two parts, namely pre-concentration processing and flotation separation. …
• After ilmenite removal, the final non-magnetic stream was subjected to traditional processing methods to generate rutile and zircon products. A simplified process flowsheet for the ilmenite circuit products is depicted in Figure 4. A WHIMS was not recommended for this application for the following reasons:
In this study, the reduction kinetics of ilmenite concentrate from a domestic mine (Kahnuj, Kerman, Iran) in pure hydrogen in the temperature range of 500 °C to 1100 °C was investigated. From the non-isothermal reduction results corresponding kinetic parameters for the as-received and pre-oxidized concentrates were calculated using the Coats-Redfern method. …
The results of research on the processing of ilmenite concentrate from the Obukhovskoye deposit are presented in this article. As the concentrate has a high chromium content, the study involved converting the iron into metal and the titanium into slag through the addition of soda. Positive results were obtained during the smelting of the ilmenite …
methods of processing ilmenite concentrate are common among acid leaching methods [6]. An excess amount of the appropriate acid and long-term heating are required for the complete extraction of titanium from ilmenite by acid methods [7]. In the case of using the chloride method, the phase composition of the original mineral raw material is not
