Place the materials that did not pass through the screen on a piece of paper and use tweezers to remove largergold particlesfrom the materials that were too large to pass through the screen.
To isolate puregold, mining companies use a complexextraction process. The first step in thisprocessis 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 gravel-like material then enters rotating drums filled with steel balls.

The primary methods used toextractminerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
Afterextraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments. Wastewater is generated during mineral processing (e.g.,stonecutting, wash water, scrubber water), from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants.
Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most meansof extractingit involve the use of water or dredging. PanningGoldpanning is mostly a manual technique of separatinggoldfrom other materials. Wide, shallow pans are filled withsandand gravel that may containgold.
