Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.

How the Electroplating Process Works - dummies
Aluminum metal is produced by reducing the aluminum oxide in a high temperature electrolytic cell using approximately 250,000 amps. That’s a lot of electricity. It’s far cheaper to take old aluminum cans, melt them down, and reform them into new cans than it is to extract the metal from the ore.
