Carbon rich pigiron is heated until it is molten. Then it is put into a ladle (large container). The molten iron is pretreated to remove impurities like silicon, sulfur and phosphorus. The iron is then moved into the BOS container and a lance is dropped inside that will blow 99 percent pure oxygen into the iron at a speed greater than Mach 1.

Review of literatures show that the level of phosphorus removal during iron ore processing in acid solutions is largely dependent on the initial and /or final pH of the leaching solution. A decrease in the final solution pH is indicative of increased phosphorus removal and dissolution in the leaching solution, hence increased acidity of the leaching solution.
