extraction of metals - introduction

From ore to metal. What are "ores"? An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite - which contains ...

Formation of a Magmatic-Hydrothermal Ore Deposit:

By stage 23 of the fluid-trapping history, the Sn concentration has dropped to only 5% of its initial value, even though the nonprecipitating elements show that the fluid mixture at that stage still contains 35% magmatic fluid. This directly demonstrates that the chemical and thermal effect (cooling) of fluid mixing was the cause for cassiterite precipitation. The precipitation efficiency can ...
