摘要： There are provided processes for preparing various products from various materials. For example, such processes are effective for extracting titanium and various other metals from various materials, thereby allowing for preparing products such as titanium chloride and titanium oxide. These processes can comprise leaching the starting material with HCl so as to obtain a leachate and a solid. The solid can be treated so as to substantially selectively extract titanium therefrom while the leachate can be treated so as to substantially selectively recover a first metal chloride therefrom.

摘要： A method of leaching of the metal contents in natural silicates by means of mineral acids to produce a metal-containing leaching liquid and a solid residue is disclosed. The silicate is first crushed but the grain size of substantially all of it is kept above 0.1 mm. It is then leached for a period of time sufficient to form a solid residue consisting chiefly of silica. The process is controlled so that the grains do not change in size or shape in the course of the leaching process. The silicate to be leached may be anorthosite or olivinrich rock and the solid residue from the leaching process may be utilized for building material, as a source for silicon in industrial processes, as a catalyst or carrier of catalysts or as an absorbent.

This sort of catalyst carrier can be namufactured through a series of steps of: (a) preparing a first alumina hydrosol having an aluminum concentration in the range of from 9.8 wt. % to 14.4 wt. % and a weight ratio of aluminum to chloride in the range of from 0.95 to 1.20, (b) preparing a second alumina hydrosol having an aluminum concentration in the range of from 9.5 wt. % to 13.0 wt. % and a weight ratio of aluminum to chloride in the range of from 0.85 to 0.95 by adding hydrochloric acid to said first hydrosol, (c) preparing an alumina precursor having an aluminum concentration in the range of from 6.0 wt. % to 7.0 wt. % by commingling said second hydrosol with a suitable gelling agent in an amount of from 1.65 to 1.85 times the chemical equivalent necessary to neutralize the chloride contained in the second hydrosol and (d) dispersing this precursor as droplets in a suspending medium thereby forming hydrogel particles, ageing the thus obtained hydrogel particles in said suspending medium and then in an aqueous ammonia, washing the aged particles in water, drying and calcining thereafter.
