Study Notes
Ores and Minerals
- Metals are often found in the Earth's crust as ores, which are compounds of metals and other elements.
- Minerals are inorganic compounds with individual crystals composed of two or more elements.
- Ore genesis, the formation of ore deposits, can occur through internal processes, like volcanic activity, hydrothermal processes, involving seawater circulating through cracks in the crust, and surficial processes, like erosion.
- Meteorites are pieces of rocky debris from space that can contain large amounts of iron ore.
- Mining is the process of extracting metal ores from deep underground.
- Gangue refers to the impurities and earthly substances found alongside the desired metal compound in ores.
Fossil Fuels
- Fossil fuels are formed from the anaerobic decomposition of organic matter over millions of years.
- They are non-renewable resources because the process of their formation is extremely slow.
- Hydrocarbons are the primary components of fossil fuels, containing carbon and hydrogen.
- The three major fossil fuels are coal, oil, and natural gas.
- Coal is a solid fossil fuel formed from plant remains. It's plentiful and easy to transport, generating a lot of energy when burned.
- Oil, also known as petroleum, is a thick liquid fossil fuel formed from the remains of small animals and algae.
- Crude oil is unrefined oil extracted from the ground.
- Refineries process crude oil into various fuels and products.
- Natural gas, primarily composed of methane, is formed from the decomposition of organic matter under pressure.
- Natural gas is used to produce electricity, steel, glass, paper, plastics, fertilizers, and many other products.
- Burning fossil fuels releases harmful emissions into the atmosphere, including carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen oxides, lead, and particulate matter.
Environmental Problems of Fossil Fuels
- Air pollution from fossil fuel combustion can cause respiratory and cardiovascular diseases, and cancer.
- Water pollution from acidic compounds released during fossil fuel burning can harm aquatic life and affect freshwater sources.
- Climate change is a major consequence of carbon dioxide emissions from fossil fuel use, which traps heat in the atmosphere and contributes to global warming.
Biomass
- Biomass is organic matter derived from plants that can be converted into energy sources like electricity, fuel, and heat.
- It is a renewable resource found worldwide.
- Wood and agricultural products, like wood logs, chips, sawdust, and agricultural waste, are major sources of biomass.
- Solid waste/landfill gas and biogas are generated from the anaerobic decomposition of organic waste in landfills.
- Ethanol is a biofuel produced by fermenting sugars and starches in plants.
- Biodiesel is a fuel made by reacting vegetable oils or animal fats with alcohol.
Advantages of Biomass
- Energy and environmental self-sustainability
- High added value products
- Total conversion of biomass without processing waste
- Potential for revitalizing abandoned industrial sites
Disadvantages of Biomass
- Lower energy efficiency compared to fossil fuels
- Not entirely clean
- Can lead to deforestation
- Requires significant space for production facilities
