Gold is a yellow and shiny. Gold is the heaviest metal, but is not very hard. Because it's soft, gold is easy to make into many shapes. It can be made into fine threads like wire or it can be hammered into thin sheets.

¨GETTING GOLD¨

¨SEPARATING GOLD FROM THE ROCK¨

One way to separate the gold from the crushed rock is to roast it or mix it with bacteria. Another way is to dissolve the crushed rock in a chemical called cyanide (say: sie-an-ide) The separated gold is washed, filtered and then melted in a furnace.

Gold mining and the environment

Gold mining can be harmful to the environment because:

•  Air is polluted by dust from open-cut mines.

• A dangerous gas can escape into the air when the crushed rock is roasted. This gas, sulphur dioxide, causes acid rain.

• The land is affected by the removal of soil and plants when mining takes place.
