Phosphorus is produced by reduction of phosphate ores with hydrocarbon gas in a stream comprising finely divided phosphate solids dispersed as a dilute solid phase in a gas stream which contains the hydrocarbon reactant. Extremely high reaction temperature is attained by heating the reactants with a gas plasma.
