18-carat gold. Along with 9-carat gold, this is the most common gold fineness found in jewellery. At around 75% gold content, 18 karat gold is cheaper than using pure gold, but maintains its lustrous yellow colour. The 25% of alloys provide more resilience to wear and tear and a tougher metal all round.
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the ...

The evolution of winches. The mid-20th century saw the development of electric winches, which revolutionised the industry. These winches were powered by electricity and could be operated with the push of a button. They were much faster and more efficient than hydraulic winches and could lift even heavier loads.
Portable electric winches can be framed up to (1) attach to a vehicle, (2) be taken out to the dredging site, or (3) even be floated on a platform, where there is deeper water. All that is needed is an automotive battery and a means of keeping it charged up. The portable hydraulic winches can be similarly effective.
6. Drum Winches. Drum winches are common on off-road vehicles and ships. The cable or rope is wound around a drum, and the pulling power is provided by an electric or hydraulic system. They are used for a wide range of applications, including lifting heavy equipment & pulling vehicles. 7. Snubbing Winches.
Electric winches, for example, are popular for their ease of use and are available in both DC and AC types. Hydraulic winches, known for their high load capacity, are ideal for heavy-duty applications. Pneumatic winches offer safety advantages in certain environments, while manual winches are simple and reliable for smaller tasks.

Panning. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.
The winch cable and boulder-harness extends down into the dredge hole. Also, the winch controls, on a cable, are waterproofed, and extend down into the dredge hole. When a boulder needs to be winched out of the hole, it is just a matter of slinging it, and winching it back, with all of the winch controls directly at your fingertips.
