1
is defined as naturally occuring, inorganic solid a definite chemical composition and an ordered internal structures
Mineral
2
Characteristics of mineral
Naturally occuring, Inorganic, Solid, Definite chemical composition, and Ordered Internal structures.
3
Chemical composition of mineral
Silicates, Oxides, Sulfides, Sulfates, Halides, Carbonates, and Native metals
4
Physical properties of mineral
Crystal form and habit, Cleavage and Structures, Luster, Color and Streak, Hardness, and Density.
5
Is one of the four interacting spheres that allow life to exist, refers tp solid Earth. It is composed of rock and regolith which is essentially aggregates of various minerals
Geosphere/ Lithosphere
6
Are composed of primarily of silicon-oxygen tetrahedrons
Silicates
7
Consist of metal cations bonded to oxygen anions
Oxides
8
They are common ore minerals along with oxides since metals form a high proportion of minerals
Sulfides
9
Consist of metal cation to the anionic group. They usually precipitate out the water near the Earth’s surface.
Sulfates
10
Are composed of halogens ion such aa chlorine or flourine which forms halites or rocks salt and flourite
Halides
11
Are the characterized by the presense of carbonic ion with bond element such as calcium or magnesium to form calcite or dolomite
Carbonates
12
Consist of single metal such as copper and gold
Native Metal
13
Since the metal have a definite chemical composition, it forms a definite structures with crystallized in specific crystal form.
Crystal form and habit
14
The manner in which a mineral breaks is dependent on its molecular bonding end structures. The tendency of mineral to break along planes of weaknesses is also known as.
Cleavage and Structures
15
Mineral described the appearance of light reflected from mineral surface. A mineral may be described as metallic, like that of a polished metal.
Luster
16
is the color of minerals in powdered form
Color and Streak
17
Measurement of the strength of the chemical bond its structures it can be measured by scratching it with another mineral or a reference material
Hardness
18
It is the weight of the mineral
Density
19
Occuring coherent aggregate of minerals such as natural glass or inorganic matter.
Rocks
20
Rocks are found?
lithosphere
21
Undergo extreme heat
Igneous rocks
22
Undergo pressure, compaction, and sedimentation
Sedimentary rocks
23
Undergo both heat and pressure
Metamorphic
24
It is profitably extract or mine (combination of minerals and rocks)
Ore
25
Extracts ore that are near the Earth surface
Surface mining
26
Extract ores that are embedded deep into the earth
Underground mining
27
Processing the mineral ore
Heap leaching
28
