The U.S. Energy Information Administration (EIA) publishes projections for energy consumption for major energy end-use sectors (residential, commercial, industrial, and transportation) and the electric power sector by major type of fuel/energy source in the International Energy Outlook 2019 (IEO2019).
Industrial Minerals (IM) publication is a specialist online service (supported by a monthly print magazine) covering all aspects of the non-metallic minerals industry. This is represented by its tagline: "from mine to market". Its independent editorial team covers worldwide pricing, news, analysis and data on 70+ minerals. Sillimanite is the best raw material for the manufacture of high alumina refractories or 55-60% alumina bricks. But its use on large scale is not possible due to its fine grading and high cost.  Dumortierite and mullite are similar mineral species found in porcelain.
