CN2011073371 METHOD FOR PREPARING METALLURGICAL-GRADE ALUMINA BY USING FLUIDIZED BED FLY ASH
As we've documented for you a number of times, as, for instance, in our report of:
West Virginia Coal Association | Iowa Improves Recovery of Aluminum from Coal Ash | Research & Development; concerning: "United States Patent 4,362,703 - Process for Preparing Cryolite from Fly Ash; 1982; Assignee: Iowa State University Research Foundation; Abstract: Cryolite (Na3AlF6) as a source of aluminum is prepared from coal fly ash by reacting the aluminum oxide (Al2O3) in fly ash with phosphoric acid to form aluminum phosphate, which is then converted to sodium aluminate by reaction with sodium hydroxide, and the sodium aluminate is converted to cryolite by reaction with hydrofluoric acid (HF), or equivalent reagent providing H+ and F- ions. Aluminum is thereby obtained from fly ash in a preferred form (as cryolite) for use in producing metallic aluminum";

As we've noted once or twice, the pace of development in Carbon Dioxide utilization technologies around the world is accelerating; and, we, here, one step at a time, have not been and will not be able to keep you adequately apprised of the developments in a truly timely way.
However, if you care about the Coal industry, and, you care about sparing your grandchildren from a lifetime of financial obligation to OPEC, reading by candlelight and wearing parkas in the house in winter, maybe it's time - - from our perspective it's way, way past time - - you started letting your Coal Country political leadership know what it is you really want them to be busying themselves with; and, letting your Coal Country press corps - - and the buyers of Sunday supplement display advertisements in the Coal Country newspapers which that press corps publishes - - know that it's time they pulled their noses out of the gas pipe, and started doing some real work, instead of just reprinting gas industry press releases that roll in on the ticker. Those are likely to start drying up anyway, just like wells in the Marcellus Shale.

We've previously documented the fact that Coal Ash can serve as an exemplary source, an ore, of some needed, even strategic, metals.
And that, in fact, shouldn't be all too surprising when you consider that Coal Ash is, in essence, just a natural mineral that has undergone some extensive preliminary refining and concentration in the boiler furnace of a power plant.

We regret what you will find to be the cluttered nature of this dispatch. And, we apologize to the exceptional Japanese company, and the accomplished scientists among their number, upon whom our dissertation is centered, for what will be the inadequate attention we will be able to devote herein to their achievements.
But, there is a lot of ground to cover.

We've made previous report on the one-time Japanese electronics giant, Panasonic Corporation, and their current apparent focus on the development of energy conversion technologies.
One such report, accessible in the West Virginia Coal Association Research and Development archives, is:
West Virginia Coal Association | Japan Hydrogen from Water and Sunlight | Research & Development; concerning: "United States Patent 7,909,979 - Water Photolysis System and Process; 2011; Assignee: Panasonic Corporation, Osaka; Abstract: The present invention provides a water photolysis system ... for photolyzing water (to produce) hydrogen and oxygen".
