A process is disclosed for recovering nickel and magnesium from natural material by extracting them in the presence of a spent sulfur containing iron based hydroconversion catalyst, under oxidative conditions.

Process for recovery of nickel and magnesium from a naturally occurring

A method for producing a catalyst for use in the hydrotreatment, hydrodemetallization and hydrocracking of heavy hydrocarbon feedstocks containing high metal levels of vanadium, nickel and sulfur comprises the steps of preparing a carrier from a naturally occurring material consisting essentially of magnesium silicate having a sheet-type structure, iron and nickel wherein the carrier is prepared directly from the above naturally occurring material or, in the alternative, it can be prepared from the naturally occurring material in combination with a catalyst component. In the event the carrier for the catalyst is prepared from the above naturally occurring material without the addition of the catalyst component, the carrier can be impregnated with the catalyst component. The resultant catalyst is particularly useful in the treatment of heavy hydrocarbon feedstocks.
