This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.

Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a catalytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers
Leach Liquor From Ilmenite Leach Plant Of Ilmenite By Selective Leaching - bosontechnology. leach liquor from ilmenite leach plant, of ilmenite by selective leaching ore is leached with a hydrochloric acid leach liquor to leaching of ilmenite from .
Product liquor from this stage is the principal lixiviant in the other (low acid) stage, although additional spent may be directed to the low-acid leach to maintain the overall plant balance. In the cocurrent process, the first-stage (low acid) leach is run under similar conditions as the first-stage leach in the countercurrent flow sheet.
leach solution was generated at an estimated 83% and 81% leach recovery for iron and titanium, respectively. Estimated leaching and oxidation time was four hours and 50 hours, respectively.

The Electrolytic Zinc procedure as described by Allen et al. (1970} was simulated by adding synthetic leach liquor containing ferric iron at a controlled rate to the precipitation vessel, which contained initially a diluted solution containing less than 1 g/1 ferric iron.
Dec 12, 2015· Leach slurry was then filtered to separate pregnant leach liquor from the residue. The resultant pregnant leach liquor was subjected to solvent extraction of iron with a high molecular weight ketone in Exxal™ 13 tridecyl alcohol and Exxsol™ D80 [ 1, 2, 23 ].
The spent leach liquor from the pre- concentrated is processed in a spray roster in which the liquid spray entering the furnace is heated by fuel oil, decomposes to metal oxides and HCl.
In the typical suphate process with ilmenite as starting titanium source, the leach liquor obtained right after cooling and removing ferrous sulfate crystals generally contains ~ 78 g/L Ti, ~ 35 g/L Fe(II) and ~ 90 g/L H 2 SO 4. Therefore, the simulated ilmenite sulfuric acid leach liquor was prepared according to the above concentrations in ...
