Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with
Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O → Mg(OH) 2), but it can be reversed by heating it
