When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire-assay, which leaves a matrix-free "button" of the metal. This button is then dissolved in the appropriate
· Updated July 02, 2019. Some metals are considered precious. The four primary precious metals are gold, silver, platinum, and palladium. Following is a look at what makes a metal precious compared with other metals, plus a list of precious metals.
Most gold and other precious metal ores contain very fine subhedral metal grains, often microscopic. Silver sometimes occurs in a wire-like or arborescent (tree-like) form (Figure 9.25). It also easily tarnishes and so has a gray color in this photo. Most bedrock gold and silver deposits are in quartz-rich hydrothermal veins.
A precious metal is a metal that is relatively rare and hence, has a very high value. So, which are the different precious metals? In the list of precious metals, given here, we shall learn about the properties of these metals and also a little about the uses of each.
sulfide minerals. …are the source of various precious metals, most notably gold, silver, and platinum.

Unlike metal sulfides, which are chemically simple compounds, REE-bearing minerals are quite complex. Base metal sulfide ores, such as sphalerite (ZnS), are typically smelted to burn off sulfur and separate impurities from the molten metal. The resulting metal is further refined to near purity by electrolysis.

· Sources of Platinum Group Metals . Platinum gets its name from platina, meaning "little silver," because the Spaniards considered it an unwanted impurity in silver mining operations in Colombia.For the most part, PGMs are found together in ores. Ultramafic and mafic igneous rocks contain high levels of platinum group metals, the granites contain a low percentage of the metals.
