PRODUCTION PROCEDURE OF FERROUS SULFIDE.

摘要

FERROUS SULFIDE IS PRODUCED BY TREATING A MELTED MIXTURE FROM A SULFUR FOUNTAIN, CONVENIENT FLOATING DEGREE IRON PYRITES, IN AN ELECTRIC INDUCTION OVEN UNTIL REACTION OCCURS, ALLOWING SLAG TO BE FORMULATED AND ELIMINATING SLOTTING. RESIDUAL. PRECAUTIONS ARE TAKEN TO PROTECT THE OVEN CIRCUIT FROM THE PENETRATING EFFECT OF IRON PIRITES DUST. THE PROCESS MAY PRODUCE A FERROUS SULFIDE WITH 35% SULFUR APPROXIMATELY, BY WEIGHT, WITH LITTLE EMISSION OF SULFUR TO THE ATMOSPHERE.
