Metal Extraction Basics

What is an ore?

• A type of rock that is always worthless.

• A synthetic material created in a lab.

• A mineral that cannot be mined.

• An ore is a natural material that contains a valuable mineral or metal that can be extracted.

Why do we extract metals from ores?

• To create alloys for better strength.

• To obtain pure metals for industrial use.

• To reduce the weight of metals.

• To recycle old metals into new products.

Why is it important to recycle metals?

• Recycling metals is only beneficial for manufacturers.

• Recycling metals increases energy consumption.

• Recycling metals is important because it conserves resources, saves energy, and reduces environmental pollution.

• Recycling metals has no impact on pollution.

What happens to the ore after metal extraction?

• The remaining ore is processed for waste management or recycling.

• The ore is discarded as waste without further processing.

• The ore is stored indefinitely in a landfill.

• The ore is converted into a different type of metal.

What is the role of heat in metal extraction?

• Heat has no effect on the extraction of metals from ores.

• Heat is only needed for cooling metals after extraction.

• Heat is used to increase the weight of metal ores.

• Heat is essential for breaking bonds in metal ores and facilitating the extraction process.
