Try to scratch one of your fingernails with the rock. If it leaves a scratch, move on to the glass and do the same thing (keep the glass on a flat surface and take care not to break it). If your rock scratches the glass, move on to the steel and see if the nail will scratch the rock. Very Soft Rocks: Won't scratch your fingernail, glass, or steel

Because mercury is liquid at room temperature, the heating process makes the mercury evaporate, leaving nearly pure gold as the remainder. The miners can then sell this to gold traders in the nearest city. As a vapor or gas, the mercury that was used in the mining process travels through the air and beyond this particular site.

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.

Most quartz forms in either igneous rocks or environments with geothermal waters. In igneous rocks, quartz forms as magma cools. Like water turning into ice, silicon dioxide will crystallize as it cools. Slow cooling generally allows the crystals to grow larger. Quartz that grows from silica-rich water forms in a similar way.
