Iron, silica, sulphur, phosphorus and copper are contained in purple ore roughly 60, 10, 1∿2, 0.02 and 0.1∿0.25% respectively. It was supposed that if the ore is reasonably reduced, the product may be used in place of steel scraps in steel manufacture. From this experience it can be said that the manufacture of sponge iron and iron lumps may be carried out industrially or commercially in a rotary kiln, tunnel kiln, reverberatory furnace, Detroit electric furnace, etc., by means of CO and solid carbon at very high temperatures. In these reducing processes, however, the elimination of sulphur is not possible and it is resulted that the product is only used in basic electric furnaces.
