The name Apache Gold is a reference to the Apache Indians ...
To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson .
The famous fire assay has been around for more than 500 years, but it still is the best method for determining the quantity of gold in a rock matrix. The fire assay process works by fusing or dissolving the rock sample in a crucible using a lead glass flux. Fluxes of various types are used on various types of ores.
In this activity, students will create a rock cycle diagram. To stretch more advanced students, encourage them to explain each process in short detail either by adding a description to the storyboard or an additional textable. Alternatively, support students who need more help by giving them a list of processes and having them label a scene.
