Abstract: A process of preparing a catalyst component for the polymerization of alpha -olefins. An organomagnesium compound is deposited on an inert inorganic support, such as silica, and the product obtained is heated at a temperature of 300-1000 DEG C in a non-reducing atmosphere. The support is then combined with one or more compounds of titanium and/or vanadium. The process of polymerizing alpha-olefins with these catalysts and a co-catalyst is also disclosed.

Abstract: Recovery of yttrium, lanthanides and radium free calcium sulphate in a phosphoric acid process by digesting phosphate rock with an excess of phosphoric acid in the presence of more than about 5 wt.% of SO4-ions calculated to the amount of phosphate rock, separating out the insoluble residue and recovering yttrium and lanthanides therefrom, precipitating calcium sulphate from the remaining solution with sulphuric acid and separating this calcium sulphate from the resulting phosphoric acid solution.
