It converts the aluminum gibbsite salts in the waste to sodium aluminate
, which also can be removed with water.
1) adjusting the temperature of the slurry of silica coated titanium dioxide particles to a temperature of from 55 to 90[degrees]C, (2) adding sufficient sodium aluminate
as a water solution to the slurry in step B (1) and adjusting the pH of the mixture formed to from 5 to 9 by addition of a strong mineral acid to deposit alumina as A1203 of from 1 to 4% by weight based on the weight of titanium dioxide particles present in the slurry of step A (1) on the surface of the silica coated particles, and digesting the resulting mixture for from 15 to 30 minutes to form the titanium dioxide particles surface coated sequentially with amorphous silica and amorphous alumina; and C.
09 % ) at 550, 750 and 950 Co by leaching sodium aluminate
in soda - based liquor in an open system and precipitating Al (OH)3 with CO2 gas than in a reflux condensed system (73.
Powdered activated carbon is added to control adverse tastes and odors, and alum and sodium aluminate
are used for coagulation.
Fourier transform infrared spectroscopy of the oxy-aluminum composites suggested some modification of the wood matrix, especially for the sodium aluminate
or aluminum hydroxide treatments.
The sodium aluminate
is separated from the insoluble iron oxide and titanium impurities.
Using sodium aluminate
adds alkalinity to the process while reducing noncarbonate hardness, as opposed to alum and ferrous or ferric salts.
The joint venture markets to customers throughout the United States, Canada and Mexico, primarily manufacturers of flame retardants, aluminum sulfate, sodium aluminate
, detergent zeolites, catalysts and aluminum fluoride.
Tenders are invited for Provide Simultaneous applications of aluminum sulfate (alum) and sodium aluminate
The sodium aluminate
solution at this point is hot, but dilute due to the dilution in the red-mud washing system.
Tenders are invited for Acquisition of sodium aluminate
Major producers of sodium aluminate
include aluminum companies.
