 Describe physical properties used to identify minerals.  Identify minerals using physical properties such as hardness and streak.

 Streak is closely related to color, but is a different property because the color of the mineral may be different than the color of the streak.color.

Silver: A Mineral By Rachel Gerstenfeld and Jessica Muchnick

Physical Characteristics Color: silver/white with exposed black tarnishing Luster: Metallic Transparency: Opaque Cleavage: Absent Fracture: Jagged Streak: Silver/White Hardness: 2.5-3

Chemical Composition Silver is an element (Ag), and it is made of only silver

Located Silver can be found in 56 countries The largest reserves are in Nevada (USA), Alaska (USA), Canada, Mexico, Peru, and China

Processing Silver-bearing ores are mined in open- underground pits The specific extractive metallurgy process is dependent on whether the silver-bearing mineral is copper, zinc, or lead

Value On , silver was worth approximately $0.64 an ounce and $ for a kilogram

What can Silver be used for? photography a catalyst for ethylene scientific equipment making mirrors jewelry dishes and tea sets electronics dental/medical equipment coins instruments water idstillation

Silver in its unprocessed form

What is a Gemstone? Why aren't all minerals gems? It’s a precious stone that is cut, polished, and used in jewelry. Gemstones are crystalline forms of mineral. Not all minerals are in their crystalline forms. Also, gemstones are specifically used in jewelry.
