Extracting Gold | HowStuffWorks

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 gravel-like material then enters rotating drums filled with steel balls.

Uranium — How Is It Mined?

The ore is drilled, then blasted to create debris which is then transported to the surface, then on to a mill. An example of a uranium mine schematic from McArthur River, Canada Source: Cameco Corp.'s filing to US Securities & Exchange Commission, March, 2022

Cyanide Use in Gold Mining - Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
