Study Notes
- The lesson will cover mineral resources
- Minerals are considered spark plugs of life because they activate thousands of chemical reactions in the body and act as a catalyst to hold the body's charge
Practical Purposes of Minerals
- Minerals are used in industrial construction for building foundations, roads bases, concrete, and drainage
- Examples of minerals used in construction include sand, gravel, clays, iron ore, and dimension stone
- Minerals are used in agriculture as fertilizers and animal feeds
- Lime in soils is an example of a mineral used in agriculture
- In the chemical industry, minerals are used as fillers and extenders to improve the density and strength of mixtures
- Salt, lime, and soda ash are examples of minerals used in the chemical industry
Negative Effects of Mining
- Mineral development may cause environmental damage
- Air, land, and water pollution can result from mining as well as damage to vegetation
- Mining can cause ecological disturbance and degradation of the natural landscape and geological hazards
Mineral Distinguishing Characteristics
- Distinguishing characteristics include crystal structure and habit, hardness, luster, diaphaneity, color, streak, tenacity, cleavage, fracture, parting, and specific gravity
- More specific tests for minerals include reaction to acid, magnetism, taste or smell, and radioactivity
Requirements for a Material to be a Mineral
- It must be naturally occurring, meaning the substance is not man-made and exists by nature without artificial aid
- It must be inorganic or abiogenic, meaning it is a substance without a carbon basis, synthesized through geological systems and processes and not produced by living organisms
- Mineral must be stable at room temperature, staying solid between 20-25°C
- It must have a definite chemical composition and all occurrences of that mineral have a chemical composition that varies within a specific limited range
- Atoms must have an ordered internal structure and must be arranged in a systematic and repeating pattern
Mohs Hardness Scale

- Talc has a Mohs hardness of 1 and a chemical formula of Mg3Si4O10(OH)2, with an absolute hardness of 1
- Gypsum has a Mohs hardness of 2 and a chemical formula of CaSO4·2H2O, with an absolute hardness of 3
- Calcite has a Mohs hardness of 3 and a chemical formula of CaCO3, with an absolute hardness of 9
- Fluorite has a Mohs hardness of 4 and a chemical formula of CaF2, with an absolute hardness of 21
- Apatite has a Mohs hardness of 5 and a chemical formula of Ca5(PO4)3(OH,Cl,F⁻), with an absolute hardness of 48
- Orthoclase Feldspar has a Mohs hardness of 6 and a chemical formula of KAlSi3O8, with an absolute hardness of 72
- Quarts has a Mohs hardness of 7 and a chemical formula of SiO2, with an absolute hardness of 100
- Topaz has a Mohs hardness of 8 and a chemical formula of Al2SiO4(OH,F)2, with an absolute hardness of 200
- Corundum has a Mohs hardness of 9 and a chemical formula of Al2O3, with an absolute hardness of 400
