Study Notes
Minerals Defined
- Minerals are naturally occurring solid substances found on the Earth's surface and deep underground, within rocks, sand, and soil.
- There are over 4,000 known minerals with new ones still being discovered.
- Minerals have a definite chemical composition and an ordered atomic arrangement.
- Minerals consist of a single element (like gold or copper) or a combination of elements.
- Rocks are made up of different minerals that merge together; granite is a rock made up of the mineral quartz.
- Minerals have a crystalline structure resembling crystals, created by processes such as volcanic activity.
Formation of Minerals
- Minerals form when water evaporates, leaving behind crystals (e.g., salt water evaporation).
- Hot water dissolves minerals as it moves through the Earth's crust, then crystallizes as the water cools.
- Magma contains different types of atoms that join together to form minerals as it cools; quartz crystallizes from magma and lava.
- Ocean animals (oysters, clams) produce calcite; the human body produces apatite in bones and teeth.
Types of Minerals
- Minerals are divided into metallic and non-metallic groups.
Metallic Minerals
- Metallic minerals have a metallic luster and are opaque; they are hard substances that conduct heat and electricity.
- Common examples include iron, copper, gold, silver, tin, uranium, bauxite, and manganese.
- They contain metals in their raw form.
- Metallic minerals are further broken down into ferrous and non-ferrous categories.
- Ferrous minerals contain iron (e.g., iron ore, manganese, and chromites).
- Non-ferrous minerals do not contain iron (e.g., gold, silver, copper, and lead).
Non-metallic Minerals
- Non-metallic minerals do not have a metallic shine or luster.
- No new product can be produced from them even if they are melted.
- Examples include sand, gravel, gypsum, halite, and dimension stone.
- They are not ductile and can be broken into pieces.
- Non-metallic minerals are derived from sedimentary rocks.
Ores
- Ores are rocks from which valuable minerals are extracted for commercial use and profit.
- The rock from which a particular mineral is extracted is called the ore of that mineral.
- Abundance does not guarantee ease of extraction; abundant minerals include aluminum, iron, and titanium, while scarce minerals include gold, silver, and copper.
- Ore minerals are generally oxides, sulfides, silicates, or native metals.
- Examples of ores include iron ore, gold ore, and uranium ore, with uranium ore extracted for nuclear energy.
Distribution of Metallic Minerals
- Iron ore is essential for manufacturing iron and steel and is the sixth most abundant element in the universe.
- Top producers of iron ore are China, Japan, and Russia.
- Copper is highly conductive and ductile, but not freely available.
- Concentrated copper reserves are in southern Central Africa, Chile, the western USA, Kazakhstan, and the Sudbury district in Canada.
- Bauxite is the primary ore of aluminum.
- Major producers of bauxite include the USA, China, India, Brazil, and Australia.
- Lead producers include Australia, the USA, Mexico, Canada, and Peru.
- In India, the Zawar mines in Udaipur, Rajasthan, produce lead ore.
- The USA, Canada, Australia, Mexico, and Japan are the main zinc-producing countries.
- Manganese is used in the production of steel.
- Important producers of manganese are Russia, India, South Africa, Ghana, Brazil, and the USA.
- Aluminum is manufactured in developed countries where cheap electrical energy is abundantly available, like Canada, Australia, and Norway.
- Silver has wider uses than gold.

- Minerals are being consumed at a fast pace and are not being provided with sufficient time to replenish.
- They take thousands of years to form, so it is necessary to conserve them.
- Use renewable energy sources like hydroelectricity and solar power to conserve mineral resources such as coal.
- Scarce minerals can be saved by substituting them with cheaper, abundant minerals.
- Minerals can be conserved by bringing efficient mining technology.
Mining
- Mining is the extraction of minerals from the Earth.
- Ore is the rock from which a mineral is ultimately extracted.
- The ore is transformed into a concentrate at the mine site.
- Copper concentrate typically contains 20-25 percent copper by weight.
- Examples of mined materials include manganese, tantalum, copper, tin, nickel, bauxite, iron ore, gold, silver, and diamonds.
- Companies mine coal, oil, and gas for fuel, metals, precious metals, and non-metallic products such as sodium, potassium, and crushed stone.
- Mined and processed products are used in homes, offices, weapons, and various means of transportation and communication.
- It takes more than 30 different minerals from the mining industry to make a television.
- Mining is preceded by geological investigations and economic feasibility analysis.
- After extraction, the run-of-mine material is cleaned, concentrated, refined, or fabricated to obtain the final product.
- Mining is simply extracting mineral wealth from the earth through excavations.
Types of Mining
- Minerals can be found on the surface of the Earth, underground, on the ocean floor, or even in seawater.
- Underground and surface mining are the most common types of mining.
Underground Mining
- Underground mining is used when an ore is deep beneath the Earth's surface or when surface mining is not appropriate.
- Access to underground deposits is by vertical shafts or sloping tunnels called 'declines.'
- Large machinery is often taken underground as dismantled parts and assembled in the work area.
- All underground mines have ventilation systems that continuously circulate fresh air.
- Longwall mining involves coal shearers cutting coal, which is then transported via conveyor belts.
- Another method involves blasting hard rock and ore from large openings known as 'stopes.'
- The mined material is brought to the surface in trucks or skips.
- Minerals containing metals are mined this way.
Surface Mining
- Surface mining means removing minerals near the Earth's surface where ore deposits are located.
- Giant earth movers remove the topsoil and rocks to extract the minerals from the deposits.
- Open-pit mining involves digging large holes, sometimes using explosives, when ore deposits are very large.
- It is the easiest and cheapest way to mine materials close to the surface.
- Strip mining involves digging long narrow strips, removing the soil and rocks above with heavy machinery, and then extracting the mineral.
- Coal and some kinds of sedimentary rocks are extracted through this method.
- Placer mining extracts alluvial deposits in sand or gravel without heavy machinery.
- Gold and other gemstones are generally mined in this process.
- Mountaintop removal mining involves blasting mountain tops to expose coal below.
- It is a relatively new method.
- Hydraulic mining involves the use of high-pressure water.
- It is a very destructive way to mine and has been discontinued.
Impact of Mining
- Mining causes deforestation and releases toxic minerals into the soil and water.
- Mining practices can ignite fires that release fly ash and smoke laden with greenhouse gases and toxic chemicals.
- Strip mining destroys landscapes and forests, leading to soil erosion and destruction of agricultural land.
- It cases dust and noise pollution when the topsoil is disrupted with heavy machinery.
- Coal mines release methane, which contributes to global warming.
- Mining destroys river banks, changes river flow, and harms aquatic life.
- Mining destroys animal habitats and ecosystems.
- Cultural degradation occurs in mining villages, destroying sacred sites and cemeteries.
- Haiari fishing in Guyana cannot take place due to river dredging for gold.
Miscellaneous Facts

- Silver is to kill bacteria in water purification systems.
- Shaft mining involves digging a vertical mine shaft until a seam rich in mineral deposits is met.
- Miners then dig horizontal shafts to extract the minerals.
- These shafts get very hot, breathing becomes difficult, rocks fall, and gas may explode.
- The deepest shaft mine is the Tau Tona gold mine in South Africa, at 3.8 km deep.
