TL;DR: In this paper, a method for preparing cryolite with high molecular ratio was proposed, which uses hydrofluoric acid, aluminium hydroxide and sodium carbonate to be synthesized continuously in several series-connected synthetic tanks with agitators.
Abstract: This invention relates to a method for preparing cryolite with high molecular ratio. It uses hydrofluoric acid, aluminium hydroxide and sodium carbonate to be synthesized continuously in several series-connected synthetic tanks with agitators. The hydrofluoric acid and aluminium hydroxide mud are simultaneously, continuously and uniformly added to the fluoaluminic acid synthesizing tank with agitator at the temp. of 70 deg.C-boiling point according to the demand which their mol ratio is 6F/Al=1.0-1.2, and reacted to obtain fluoaluminic acid, then the fluoaluminic acid and sodium carbonate solution are continuously and uniformly added to its cryolite synthesizing tank according to the mol ratio of that Na/Al is greater than 3 so as to obtain the high molecular ratio cryolite whose mol ratio of WaF and AlF3 is greater than 2.7, tilter property is good and impurity content is low.

TL;DR: The physicochemical properties of sodium aluminate solutions are modified by adding different surfactants, and the variations of the surface tension, viscosity as well as the conductivity are investigated in detail as mentioned in this paper.
Abstract: The physicochemical properties of sodium aluminate solutions are modified by adding different surfactants, and the variations of the surface tension, viscosity as well as the conductivity are investigated in detail. The modification of the properties of the solution is correlated with the aluminium hydroxide precipitation process from the solution (Bayer process). The results indicate that the precipitation ratio, the crystal size, as well as the intensity of the Al(OH)3 products can be enhanced after addition of certain types of surfactants. The chemical compositions of the surfactants are reported and it can be shown that novel types of surfactants prepared by mixing different, relatively cheaper components exhibit the potential to replace the more expensive recipes commercially available. These improvements to the precipitation process are interpreted as being due to modification of the properties of the sodium aluminate solution after addition of the surfactants.

TL;DR: In this paper, a process for obtaining a granular zeolite from naturally occurring argillaceous material is described, in which the initial raw material is mixed with a neutral aluminium salt and caustic soda, aluminium hydroxide or silicon dioxide being introduced into the reaction mixture at the same time; the mixture is subjected to steam-heat treatment followed by thermal activation, and is then mixed with an alumino-silico-hydro gel until a homogenous slurry is formed.
Abstract: A process is disclosed for obtaining a granular zeolite from naturally occurring argillaceous material. The invention relates to the field of processing natural materials, in particular the production of granular synthetic zeolites. The invention permits the use of a wide range of natural clays, widens the raw material base for manufacturing granular synthetic zeolites, and boosts the active zeolite content in the granules. To these ends the initial raw material is mixed with a neutral aluminium salt and caustic soda, aluminium hydroxide or silicon dioxide being introduced into the reaction mixture at the same time; the mixture is subjected to steam-heat treatment followed by thermal activation, and is then mixed with an alumino-silico-hydro gel until a homogenous slurry is formed. The neutral aluminium salt used can be, for example, aluminium sulphate. The argillaceous raw material, neutral aluminium salt and sodium hydroxide are mixed in the following respective proportions: 100 : 0.05 : 0.02. The mixture is steam-heat treated for 10 to 60 minutes at a temperature of 110 to 250 °C.
