In 1795 Klaproth succeeded in separating an oxide of the new element from the mineral brought from Hungary. Now this mineral is known as rutile (TiO2). The oxide separated by Klaproth and the menaccin earth found by Gregor turned out to be very much alike. Soon Klaproth established that he and Gregor had discovered the same element.

The main commercial value of RuO 4 is as an intermediate in the production of ruthenium compounds and metal from ores. Like other platinum group metals (PGMs), ruthenium occurs at low concentrations and often mixed with other PGMs. Together with OsO 4, it is separated from other PGMs by distillation of a chlorine-oxidized extract.
