DEFINITION

Classification: 75/958

WITH CONCURRENT PRODUCTION OF IRON (FE) AND OTHER DESIRED NONMETALLIC PRODUCT (E.G., ENERGY, FERTILIZER, ETC.):

Art collection of patents in which other products are intentionally produced along with Iron (Fe). Excluded are the normal by-products such as flue gas and slag. However, if the Iron (Fe) making process is intentionally modified so that the by-products have special utility a cross-reference is placed here. As an example, if slag is specifically made to be high in phosphorus so that it is a good fertilizer a copy of the patent should be placed here.
