Bauxite is the name for any ore that has a large amount of aluminum hydroxide- a chemical combination of aluminum oxide and water. Aluminum oxide, also called alumina, is the compound from which aluminum is made. Most bauxite consists of 30 to 60 percent alumina and 12 to 30 percent water. It also contains iron oxide, silica, and titanium oxide. The color of bauxite depends chiefly on how much ...

This hydrogen could be generated from natural gas or other renewable resources. Another significant advantage of fuels derived from waste biomass is that they are a way to control global warming caused by the combustion of fossil fuels. The carbon dioxide released from the combustion of biomass is balanced through photosyn...
