Panning for gold was also known as quotplacer mining.quot Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.

Once the excavator transporter brings the raw material to the crusher for processing, the feeding device feeds the material into the crusher and in return the material is screened and all oversized material is recirculated back to the crusher to ensure correct size fraction is obtained. This weighbelt feeding equipment, usually referred to as Weighfeeders, conveys and controls the feedrate into the crusher to improve crusher efficiency.

According to the Bureau of Labor Statistics, the mining industry consists of five major segments coal mining, gas and oil extracting, metal ore mining, non-metal mineral mining and supporting activities such as resource transportation. Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment includes excavators, draglines, drills, roof bolters, continuous miners, longwall miners, rock dusters, shuttle cars and scoops.
Miners traditionally used shovels and steam shovels to break and remove earth, but todays miners rely on excavators. An excavator is a mobile vehicle that moves on tracks or with standard wheels. It features a rotating platform, off of which comes a hinged arm with a bucket or scoop attached to its end for digging.
