A collection of process equipment for placer gold ore separation

Placer gold deposits are a type of gold deposit that is formed by the weathering of primary gold deposits and the subsequent transportation of gold particles by water. Placer gold deposits are usually found in riverbeds, alluvial plains, and on beaches. Because placer gold deposits are often rich in gold and easy to mine, they have been the focus of gold mining for centuries.

The process of separating placer gold from the surrounding sediment and minerals is called placer gold ore separation. The process of placer gold ore separation is different from that of primary gold ore separation, as placer gold deposits are often mixed with sand and gravel, making the process more complex.

The process of separating placer gold ore can be broken down into several steps. The first step is to remove the large rocks and debris from the area where the placer gold deposit is located. This is done using a bulldozer or excavator.

The next step is to excavate the gravel and sand that contains the placer gold particles. This is done using a dredger, which is a type of excavation equipment that can remove large amounts of sediment from the riverbed or alluvial plain.

Once the gravel and sand have been excavated, they are transported to a processing plant. The processing plant is where the placer gold ore separation takes place. The processing plant consists of several pieces of equipment that are used to separate the gold particles from the sand and gravel.

One of the most important pieces of equipment in a placer gold ore separation processing plant is the sluice box. A sluice box is a long, narrow box that is placed at an angle in the water. The water flows through the sluice box, and the gold particles are trapped in the riffles that are built into the bottom of the box.

Another important piece of equipment in a placer gold ore separation processing plant is the shaking table. A shaking table is a device that uses gravity to separate the gold particles from the sand and gravel. The shaking table is made up of a flat surface that is tilted slightly. The gold particles are placed on the flat surface, and the table is shaken back and forth. The heavier gold particles settle to the bottom of the table, while the lighter sand and gravel particles are washed away.

Other equipment used in a placer gold ore separation processing plant includes jigs, spiral concentrators, and magnetic separators. Jigs are used to separate the gold particles based on their density, while spiral concentrators use centrifugal force to separate the gold particles from the sand and gravel. Magnetic separators are used to remove any magnetic minerals that may be present in the sand and gravel.

In conclusion, placer gold ore separation is a complex process that requires the use of several pieces of equipment. The equipment used in a placer gold ore separation processing plant includes sluice boxes, shaking tables, jigs, spiral concentrators, and magnetic separators. Each piece of equipment plays a specific role in the process, and together they help to extract the valuable gold particles from the surrounding sediment and minerals.
