magnesium In magnesium processing: Ores and raw materials Among the ore minerals, the most common are the carbonates dolomite (a compound of magnesium and calcium carbonates, MgCO3·CaCO3) and magnesite (magnesium carbonate, MgCO3).
Antimonial lead. The most common and important metal alloyed with lead is antimony. Antimonial lead alloys usually contain from 1 to 6 percent antimony, but they may contain as much as 25 percent. Other components usually include tin, iron, copper, zinc, silver, arsenic, or traces of nickel.
For many years lead was obtained primarily from lead ore. The largest deposits of lead ore can be found in China, the USA, Australia, Russia and Canada. The European countries do not have such large lead ore deposits, but within Europe Sweden and Poland have the largest. Lead is hardly obtained from lead ore anymore, however,...
