It's Elemental

Although aluminum is the most abundant metal in the earth's crust it is never found free in nature All of the earth's aluminum has combined with other elements to form compounds Two of the most common compounds are alum such as potassium aluminum sulfate (KAl(SO 4) 2 12H 2 O) and aluminum oxide (Al 2 O 3) About 8 2% of the earth's crust is composed of aluminum

Why Should We Recycle Aluminum?

Recycling aluminum saves 90% to 95% of the energy needed to make aluminum from bauxite ore It doesn't matter if you're making aluminum cans roof gutters or cookware it is simply much more energy-efficient to recycle existing aluminum to create the aluminum needed for new products than it is to make aluminum from natural resources

How Does Lithium Mining Actually Work and Will We Have Enough?

A more diverse lithium supply could also help break up the oligopoly that currently controls the trade Today just four companies (Chile's SQM U S -based FMC Corp and Albemarle Corp and Australia's Talison) produce 85 percent of all lithium Finally expanding lithium mining operations could insulate lithium prices against potential shocks
