Mining tools are essential for extracting minerals and other materials from the earth. The pickax, also known as a pick, is a tool with a hard head attached to a handle, used for breaking up rocks and soil. A CRADLE, also known as a rocker box, is a device used in placer mining to separate gold from gravel and dirt. Finally, a TREPAN is a type of drill bit used to cut into hard surfaces such as rock or metal. All three of these tools are commonly used in mining operations.
