Methods for Separating Mixtures Chemistry for Non-Majors

One of the approaches taken to isolate the gold from the soil was called “panning.” Dirt would be placed in the pan and covered with water. After thorough mixing the pan is gently swirled to remove dissolved material while the heavier gold settles to the bottom of the pan. The gold is then separated from the mixture of soil and water.

Removing the gold-bearing rock from the ground is just the first step. 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.
