Deep in the Earth's crust, silver is one of the important metals that can be found, along with gold, copper, lead and zinc. It is formed by forming compounds with sulfur. Due to hot temperature, salty water called brine dissolves, collects and concentrates silver into the brine. Once the brine mixes ...
Sandstone is a very common sedimentary rock and perhaps the best known sedimentary rock. It is formed in many environments. Just about anywhere there is water, whether frozen or not, in a river or ocean, there is a chance to form sandstone.
Sep 11, 2018· The minerals formed from this type of magma are often valuable because they have concentrations of rare chemical elements. When magma cools very slowly, very large crystals can grow. These mineral deposits are good sources of crystals that are used to make jewelry. For example, magma can form large topaz crystals.
In gold regions, gold is also found in the sand and gravel that is formed by the washing down of the weathered rocks and gold veins; this is known as placer or alluvial gold, and it is accompanied by such hard, heavy minerals as magnetite, garnet, zircon, topaz, corundum, etc., and sometimes by platinum.
Minerals such as these are called native elements. Other native elements that have been found in Pennsylvania include sulfur (S), copper (Cu), and very rarely, silver (Ag) and gold (Au).

The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral.
Aug 04, 2015· Because the copper solidifies later than other minerals within the larger rock, the final deposits have a high concentration. Copper appears most frequently in deposits in which lead, silver, gold and zinc are also present.

Magma formed various intrusions into shallow parts of the earth's crust. PGEs can be therefore be found among mafic and ultramafic volcanic (igneous) rocks. Platinum shines with a silvery color, but it does not tarnish like silver.
Silver mining is the resource extraction of silver by mining. Silver is found in native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S ), chlorargyrite ("horn silver," Ag Cl ), and galena (a lead ore often containing significant amounts of silver).
They are distinctly banded (segregation of newly formed minerals into bands), and their main minerals are quartz, potassium feldspar, and biotite or hornblende (ferromagnesian minerals). It is of similar composition than granite, and if a gneiss is heated just a little bit further, a granitic melt will rise from it.
Emeralds are formed of a mineral called beryl whose chemical formula is a complex mix of beryllium, aluminum, silicon, and oxygen. The color comes from additional traces of chromium and vanadium.

Jan 16, 2014· Metal: Platinum is the rarest and most expensive precious metal – more so than either gold or silver. And platinum crystals are even rarer – so rare that, until a few years ago, they were considered to be the rarest objects on the face of the earth!
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth's crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions ...

Platinum is found in its pure native form or in platiniridium, a natural alloy of platinum and iridium. Platinum is present in thin sulfide layers in certain mafic igneous bodies and is mined in Canada, Russia, South Africa, the USA, Zimbabwe and Australia.
Silver bonds to tellurium in the mineral hessite, Ag 2 Te. Gold and silver combine with tellurium to form the mineral sylvanite, AgAuTe 4 . It fills all ten 4d states before it fills the second 5s state.
Sulfide mineral: Sulfide mineral, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic luster and electrical conductivity.
Silver has many unique physical properties that give it very special status. Silver is the best conductor of electricity, is the second most malleable and ductile metal, and is in greater abundance than all other precious metals with similar properties. Due to its unique properties and intrinsic beauty, it is extensively used industrially and as ornaments.
