1.
What are the types of mining? (Check two)
Correct Answer(s)
B. Strip mining
E. Underground mining
Explanation
Strip mining and underground mining are both types of mining. Strip mining involves the removal of the earth's surface layer to extract minerals or other valuable resources. This method is commonly used for extracting coal, oil sands, and other shallow deposits. On the other hand, underground mining involves accessing mineral deposits beneath the earth's surface through tunnels and shafts. This method is typically used for extracting minerals such as gold, silver, and copper. Both strip mining and underground mining have their own advantages and disadvantages and are used depending on the specific characteristics of the deposit being mined.
2.
What is the purpose of processing ore?
Correct Answer
A. To remove unwanted rock
Explanation
The purpose of processing ore is to remove unwanted rock. Processing ore involves various techniques such as crushing, grinding, and separating the ore from the waste rock. This is done to extract valuable minerals or metals from the ore, as the unwanted rock does not contain the desired minerals. Removing the unwanted rock allows for a more concentrated and pure form of the desired minerals, making it easier to further process and extract the valuable components.
3.
How is ore processed?
Correct Answer
C. It's put in a tank filled with water and a variety of chemicals, then in a high-temperature furnace
Explanation
Ore is processed by first putting it in a tank filled with water and a variety of chemicals. This process helps to separate the valuable minerals from the waste material. After that, the mixture is transferred to a high-temperature furnace where the ore is heated to extract the desired minerals. The high temperature helps in melting the ore and separating the impurities, leaving behind the valuable minerals.
4.
Who are mining lobbyists?
Correct Answer
E. People who are hired by mining companies to get support for the mining industry
Explanation
Mining lobbyists are individuals who are hired by mining companies to advocate for and promote the interests of the mining industry. Their role is to influence policymakers, lawmakers, and the public in order to gain support for mining activities and policies that benefit the industry. They work to shape legislation, regulations, and public opinion to ensure favorable conditions for mining operations and to counter any opposition or negative perceptions surrounding the industry.
5.
How many different minerals are you utilizing every time you turn on your television?
Correct Answer
B. 35
Explanation
The correct answer is 35. When you turn on your television, you are utilizing various minerals that are used in the production of electronic components. These minerals include but are not limited to copper, aluminum, gold, silver, and rare earth elements. The number 35 represents the approximate number of different minerals that are utilized in the manufacturing process of televisions.
6.
What is one example of a political party that is against mining?
Correct Answer
D. The Green Party of B.C.
Explanation
The Green Party of B.C. is an example of a political party that is against mining. The party's stance on mining aligns with their environmental focus and commitment to sustainability. They prioritize the protection of natural resources and advocate for alternative, renewable energy sources.
7.
How much liquid waste, or tailings, can producing a single gold ring generate?
Correct Answer
A. 20 tonnes
Explanation
Producing a single gold ring can generate 20 tonnes of liquid waste, or tailings. This is a significant amount of waste considering the small size of the final product. Gold mining involves extracting gold from the earth, which requires large amounts of water and the use of chemicals. These chemicals and waste materials are often released into nearby water sources, causing pollution and environmental damage. The high volume of liquid waste generated highlights the environmental impact of gold production and the need for more sustainable mining practices.
8.
What is mining?
Correct Answer
D. Extraction of minerals and metals from the Earth's Crust
Explanation
Mining refers to the extraction of minerals and metals from the Earth's crust. It involves the process of digging, drilling, and extracting valuable resources such as coal, gold, iron ore, and diamonds. Mining plays a crucial role in supplying raw materials for various industries and is essential for economic development. This process involves identifying mineral deposits, extracting them from the ground, and processing them to obtain the desired materials. Mining is not related to agriculture or the artificial creation of minerals; instead, it is focused on the extraction of natural resources from the Earth's crust.
9.
What is the cheapest way of mining?
Correct Answer
A. Open-pit mining
Explanation
Open-pit mining is the cheapest way of mining because it involves excavating the surface of the earth to extract minerals or other valuable materials. This method is cost-effective as it does not require extensive underground tunnels or shafts, which can be expensive to construct and maintain. Instead, large open pits are created, allowing for easier access to the resources. Additionally, open-pit mining allows for the use of larger machinery and equipment, leading to increased efficiency and productivity in the mining process.
10.
What is the challenge to the mining companies?
Correct Answer
C. Protecting the environment
Explanation
Mining companies face the challenge of protecting the environment. Mining activities can have significant negative impacts on the environment, such as deforestation, habitat destruction, water pollution, and air pollution. These activities can harm ecosystems, wildlife, and local communities. Therefore, mining companies need to implement measures to minimize these environmental impacts, such as using sustainable mining practices, reclaiming land after mining, and reducing pollution. This challenge requires balancing the need for extracting minerals with the need to preserve and protect the environment for future generations.
