Ilmenite Ore Processing Diagram
Alkali roasting of ilmenite and anatase ores bomar ilmenite temperature 1073 1273 k time 120 min na 2 co 3 or nahco 3 in the charge was varied stoichiometric amount required for tio 2 fe 2 o 3 al 2 o 3 and sio 2 in the ore alumina leaching hot water leaching acid leaching 5 hcl solution 343 353 k temperature.
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.
the diagram shows the production of titanium dioxide via the sulfate processcaption ilmenite processing initially ilmenite ores are dried to a moisture content of less than 01 and ground to give a mean particle size of less than 40 mm this prevents heating and premature reactions downstream the finely ground titaniumbearing ore is.
ilmenite is a compound of ferrous oxide and titanium dioxide and rutile is a compound of titanium dioxide after the separation of the titanium values the titanium values are retained as the desired product and the silicates are discarded in us pat no 2904177 a flotation method is used for the removal of silicates from an ilmenite ore.
Based on mineral processing tests an ilmenite concentrate by grading of 445 tio 2 has been obtained by a combination of the gravitymagnetic separators mehdilo 2003 irannajad and mehdilo 2007 irannajad schematic diagram of ilmenite concentrate and titanium slag preparation from ore sample table 1 chemical composition of ore.
Chromite ore processing flow chart flow diagram of processing of chromite ore chromite processing plant flow chart extraction of chromium from chromite ore chromite flow chart flowchart wikipedia a flowchart is a type of diagram that represents an algorithm workflow or process showing the steps as boxes of various kinds and their order by connecting beneficiation chromite processing plant.
