Minerals & Ores & The Extraction Of Minerals

The video tutorial explains the concept of minerals and ores, highlighting that minerals are naturally occurring elements or compounds, while ores are rocks with a high percentage of a specific mineral. It provides examples of ores like hematite, malachite, and cinnabar, and discusses the economic benefits of extracting minerals. The tutorial covers the reactivity series and the process of extracting metals through single displacement reactions. A demonstration of copper extraction from malachite is included, and the video concludes with a discussion on native metals like gold and platinum.

What is a mineral?

• A type of metal

• A synthetic rock

• A naturally occurring element or compound

• A man-made element or compound

Which of the following is an example of an ore?

• Granite

• Sandstone

• Hematite

• Basalt

Why is it economically beneficial to extract minerals from ores with a high percentage of the desired mineral?

• It yields more of the desired mineral

• It is more environmentally friendly

• It requires less energy

• It is faster

What type of reaction is used to extract metals from ores?

• Decomposition reaction

• Synthesis reaction

• Single displacement reaction

• Double displacement reaction

In the reactivity series, where are the most reactive metals located?

• At the top

• They are evenly distributed

• In the middle

• At the bottom

What is the role of carbon in the extraction of copper from copper II oxide?

• It oxidizes copper

• It displaces copper to form copper metal

• It forms a compound with copper

• It acts as a catalyst

Which metals are typically found as native metals and do not require extraction from ores?

• Lead and tin

• Aluminum and zinc

• Iron and copper

• Gold and platinum
