2. Copper
Copper was one of the first metals to be
worked into implements and the first
metal to be smelted from ores. Its
excellent ductility and high conductivity
assure its use in modern society.
3. Gold
Gold is one of the most popular
and well-known minerals, known
for its value and special properties
since the earliest of time.
4. Description: One of the most valuable metal in our industry today because it is widely used in different industries. almost 70 percent of platinum production is used by the jewelry industry and the catalyc
Platinum

plumbum, meaning soft metal.
9. Chromium
Chromium is a trace mineral that
is found in very small amounts in
the human body.
10. Lime
Limestone is a sedimentary rock composed
largely of the minerals calcite and aragonite,
which are different crystal forms of calcium
carbonate (CaCO3).
11. Zinc
Zinc is an essential mineral that
stimulates the activity of about
100 enzymes in the body
