A process for hydrofluoric acid digestion of inorganic silica/alumina matrix material for the production of silicon tetrafluoride and aluminum fluoride comprises the initial step of reacting the matrix material with hydrofluoric acid, to form silicon tetrafluoride gas and a solution/slurry containing aluminum fluoride, undigested oxides, and additional soluble and insoluble fluoride materials.

Method for hydrofluoric acid digestion of silica/alumina

The process for hydrofluoric acid digestion of silica/alumina matrix material for the production of silicon tetrafluoride and aluminum fluoride and other heavy metals involves the following general equations: I. Separation silica/alumina matrix material as SiF 4 (g) and AlF 3: SiO 2 /Al 2 O 3 +10HF SiF 4 (g) +2AlF 3 (aq) +5H 2 O . II.

About this site

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2
