2 What’s It Made Of? METAL Created by Ellen Weber, Ed.S., CCC-SLP, 2008

3 There are 72 different metals that are known today. Most metals come from the ground. goldsilvercopper Sometimes you can find them in nuggets. A nugget is a small chunk of the metal all by itself.

4 Sometimes nuggets wash down from the mountains. You might find nuggets in rivers and streams.

5 This girl is panning. You swish some ground around in a pan with water, and the gold will separate from the dirt. This is how they get the nuggets out of the rivers and streams.

6 Gold mining companies use big dredges on a river. Dredges do the same thing as panning – they separate the gold from the dirt.

7 Lots of other kinds of metal are mixed in with other things inside rocks. It’s a little harder to get the ore out of the rock. This is called ore.

8 Mining companies dig the ore out of the ground. This place is called a mine. Sometimes they dig long tunnels deep into the earth. It’s very dangerous to work in these tunnels.

9 Sometimes they dig a strip mine. This is where they cut away the ground in layers that look like steps.

10 They haul away the rocks in huge trucks called rock haulers. See how big it is compared to a regular SUV? Just the tires are as tall as a house!

11 Then they heat the rocks until they melt. When it melts, the metal can be separated from the other minerals in the rock. This is called smelting.

12 A person who digs for metals is called a miner. A miner uses special tools and wears special clothing for his job.
