The present invention concerns an industrial chemical process (400f) and an apparatus for carrying out that process.

This combined method has the iron and / or manganese ore and the other ore comprising the carbonate mineral as its only essential ingredients, with common salt and / or water as optional extra ingredients. The combined method produces iron and / or manganese in elemental form, an oxide or hydroxide derived from the carbonate mineral, and oxygen as its corresponding products. If the iron and / or manganese ore also comprises a siliceous mineral, the method may also produce an alkaline mixture comprising sodium silicate as a co-product. Salt and water act as intermediaries to produce these end-products, but are only consumed if supplied in excess. An amount of sodium oxide, hydroxide and / or carbonate determined by the amount of salt consumed may be produced as a co-product, along with a corresponding amount of at least one of chlorine and hydrochloric acid. An amount of hydrogen determined by the amount of water consumed may also be produced as a co-product, along with an increased amount of oxygen. The iron, manganese and oxygen produced may all be used in steelmaking. Any excess oxygen may be safely vented to atmosphere. The oxide or hydroxide derived from the carbonate mineral may be used in cement manufacture, as a flux in steelmaking and / or as an ingredient in the manufacture of soda-lime glass. The alkaline mixture comprising sodium silicate may be used as an alkaline activator for an alkaline activated or geopolymer cement. The sodium carbonate may be used in the manufacture of soda-lime and / or borosilicate glass, for example. The chlorine and / or hydrochloric acid may be used in the manufacture of chlorinated organic compounds, for example. The hydrogen may be used as a fuel in a hydrogen economy. The method of the invention requires no nett input of heat because the chemical reactions it involves are exothermic overall. It also consumes no fossil fuels and has electricity as its only energy requirement. Thus if the electricity is produced from a source of renewable energy, this method produces no greenhouse gas emissions. In some embodiments, the method can even have a negative carbon footprint overall. The invention is intended to replace existing techniques for producing iron and / or manganese from their ores, including hydrogen-DRI, the calcination of limestone and other carbonate minerals, both in cement manufacture and in the production of lime for other purposes, and the ammonia-soda, or Solvay, process for the production of sodium carbonate. The invention therefore has the potential to eliminate up to about 20% of anthropogenic carbon dioxide emissions. [Fig. 9B]
