Ore And Minerals Quiz! Trivia

Ore is a naturally-occurring material from which minerals of economic value can be extracted. It is a rock or mineral deposit that contains a high enough concentration of valuable minerals, such as metals, to be economically feasible to mine and process. Ores are typically formed through geological processes, such as the cooling and solidification of magma or the deposition of sediments, and they can be found in various types and grades depending on the specific minerals they contain.

A potential ore body is considered a deposit when the abundance of the ore body is greater than the average abundance on the Earth's crust. This means that the concentration of the valuable minerals or metals in the ore body is higher than what is typically found in the Earth's crust. This higher abundance makes it economically viable to extract and process the minerals or metals from the ore body.

The given answer states that "Additional costs outweigh the potential profit" is not a quality of a good resource. This means that a good resource should not have additional costs that are greater than the potential profit it can generate. In other words, a good resource should be profitable and not burdened by excessive costs that negate its value. The other options mentioned in the question, such as not being too expensive to mine and not being too far from a market to transport, are qualities that contribute to the overall value and feasibility of a resource.

Palawan is known for having a lot of nickel deposits. Nickel is a mineral that is commonly found in the earth's crust, and Palawan has been recognized as one of the major sources of nickel in the Philippines. The island is home to several mining sites and has a significant contribution to the country's nickel production. Therefore, Palawan is the correct answer for finding a lot of nickel deposits.

Kimberlite magma is the correct answer because it is a special type of magma that originates deep within the mantle and is known to be the source of highly prized diamonds. Kimberlite magma is rich in volatile substances and is often found in vertical pipes or conduits that bring the diamonds to the Earth's surface through volcanic eruptions. This type of magma is unique in its ability to transport diamonds from the mantle to the surface, making it highly valuable in the diamond mining industry.

Laterites are a type of soil that is rich in iron and aluminum. They form in tropical and subtropical regions with high rainfall. Nickel, magnesium, and iron are commonly found in laterites due to weathering and leaching processes. However, silver is not typically found in laterites as it does not undergo the same weathering and leaching processes as the other minerals mentioned. Therefore, the correct answer is silver.

Platinum is a common placer ore deposit because it is often found in alluvial deposits, such as riverbeds or beach sands, where it has been concentrated by natural processes like erosion and sedimentation. Placer deposits are formed when heavy minerals, like platinum, are transported and deposited by water, leaving behind valuable concentrations in easily accessible locations. This makes platinum a common choice for mining operations as it can be extracted relatively easily from these placer deposits.
