Pyrargyrite is a popular silver bearing mineral for collectors. Its color is a dark red and is most commonly so dark that it appears black. The nickname "Ruby Silver" has been applied to pyrargyrite although it is typically applied to the related mineral proustite. Pyrargyrite is isostructural with proustite, a silver arsenic sulfide. . Isostructural means that the two minerals have the same
In the Middle Ages, the alchemists of the day tried in vain to create the “philosopher’s stone”, which could be used to create gold and obtain immortality. Obviously they never obtained a “philosopher’s stone” Modern scientists also disagree on where gold comes from. Some Scientists believe that gold came from outer space, that an []

Which one of the following mineral ores is formed by decomposition of rocks, leaving a residual mass of weathered material? (a) Coal (b) Bauxite (c) Gold (d) Zinc (b
18-05-2015· Gold isn’t truly formed—at least, not on Earth. Gold Comes From Outer Space Gold, the shiny yellow metal prized for its beauty and malleability and used in many different industries,is actually created inside massive stars when they explode into a supernova.
A rock is a compound composed of two or more minerals. It is classified into three types based on how it is formed igneous, sedimentary and metamorphic. Meanwhile, a mineral is grouped in
The price of silver, therefore, was considered expensive, and the demand for the mineral was high. In 1792, the price of silver was $0.456 per gram, and rose to the highest price of $0.104 per gram in 1864. The price of silver decreased in the years to follow. However, prices rose again in the early 1900s into 1979, when silver was at its
Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
Silver mining is the resource extraction of silver by mining.. Silver is found in a 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," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with

Dark minerals are iron-rich biotite and pyroxene augite. Larvik, Norway. Width of sample 9 cm. Phlogopite in glimmerite-carbonatite. Carbonatite is igneous rock with highly unusual carbonate composition (white mineral is calcite). It is usually phlogopite when biotite group mica is associated with carbonate minerals in igneous or metamorphic rocks.
Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
