On the other hand, vacuum crushing and stepwise heating are methods employed to extract the volatiles and measure their chemical and isotopic compositions using mass spectrometry. An improved vacuum stepwise heating technique can effectively separate volatiles in different occurrence modes in mantle materials, which in combination with mass

The extraction of gold from below the earth's surface could have started as early as 7,000 years ago. This is evidenced by the gold jewelry and other artifacts of antiquities found in the Varna Necropolis gravesites in Bulgaria, which was built sometime between 4,700 BC and 4,200 BC.

Mining of Minerals To mine minerals, geologists must first locate them and then extract them from the lithosphere. Quebec is known for its deposits of gold, copper, zinc, nickel and iron. The extraction of minerals can be done from an open pit mine or and underground mine. Rocks Rocks are heterogeneous solids composed of many minerals.

Many commercially-important transition metals, such as copper, cobalt, nickel and zinc, occur either predominantly or in significant amounts in the lithosphere as sulfide minerals, whereas others, such as native gold and uranium (in uraninite) are associated with sulfidic minerals (pyrite, arsenopyrite, etc.) in some ore deposits.

The mid-ocean ridges migrate over the Earth like Roombas, extracting this basaltic component from the peridotite of the mantle as they go. This works like a chemical refining process. Basaltic rocks contain more silicon and aluminum than the peridotite left behind, which has more iron and magnesium. Basaltic rocks are also less dense.

There are different ways to extract minerals from a deposit. • Quarries or open pit minesare holes or cuts that are on or near the surface. • Underground minesare shafts, tunnels and galleries that are deep inside the Earth. • Drillingis when a deep hole is made.

In modern times several new techniques are used to extract the mineral from the ore, in addition to smelting. The most common methods are flotation, leaching and use of redox reactions. Leaching involves mixing the ore with a carefully chosen liquid that dissolves either the mineral or the unwanted minerals. The liquid is often an acid.

Oceanic crust, being so thin, is a very small fraction of the Earth -- about 0.1 percent -- but its life cycle serves to separate the contents of the upper mantle into a heavy residue and a lighter set of basaltic rocks. It also extracts the so-called incompatible elements, which don't fit into mantle minerals and move into the liquid melt.

Coal mines generally extract coal - which is classified as a rock rather than a mineral. A mineral is considered to be a naturally ocurring substance with a definite chemical content. Coal has a variable chemical content. As for mining processes, they are quite variable. The most productive underground method is known as longwall.
