Diamond washing plant

Types of diamond washing plants

A diamond washing plant is a piece of industrial equipment that separates diamonds from other materials. Several types of diamond washing plants exist, and each uses a different approach to extract diamonds from gravel, sand, or other materials.

• Rotary trommel washer plants:

  This washing plant has a rotating cylindrical drum used for the pre-concentration of materials. Operators feed raw materials into the drum, which separates the materials according to size. Smaller particles exit the drum, while larger ones continue to the next processing stage. The trommel's slope and rotation speed determine the separation efficiency.

• Rotary drum washer plants:

  It is similar to the trommel washer but features a circular container that mixes water and washing materials. The friction between raw materials and the drum surface causes impurities to fall off.

• Vibrating screen diamond wash plant:

  The vibrating screen washer uses a deck that vibrates rapidly to separate different materials. The gravel material goes through the screen holes, while larger diamond-containing materials remain on the screen deck for further processing. Sometimes water is sprayed onto the vibrating screens to wash away impurities.

• Jigging diamond wash plant sinks:

  This kind of washing plant separates diamonds from other materials using water and air currents. The jigging sinks have a pulsating water column that lifts and drops raw materials. The diamond-bearing materials remain at the bottom and are collected, while lighter materials are washed away.

• Whirling washing plants:

  In these plants, the raw material input turns rapidly. Gravity then separates materials according to density. Heavier materials, like diamonds, sink to the bottom and are collected. Lighter materials are washed away.

• X-ray luminescence diamond wash plant:

  This plant uses X-ray technology to detect and separate diamonds from other materials. An X-ray machine scans the processed materials. The data reveals diamond locations, and the diamonds are separated using an automated system.

• Heavy media separation (HMS) diamond plants:

  HMS diamonds wash plants separate materials based on density differences. The plant applies a heavy liquid, like water mixed with magnetite, to the raw materials. Heavier materials, including diamonds, sink. Lighter materials float and are removed from the processing system.

Specifications and Maintenance of Diamond Washing Plants

Scenarios of diamond washing plants

Diamond washing plants are used in several industries that rely on diamonds for their operational needs. Here are some of the key application areas of diamond washing plants:

• Industrial diamond extraction: Mining companies rely on diamond washing plants to separate diamonds, impact drills, and other valuable materials after diamond ore. Plants like the DMS are especially popular in mining operations as they aid in the rapid and early identification of diamonds within the ore matrix. Once the wash water recirculates through the plant, the diamond-bearing material is processed to extract the diamonds and leave the non-valuable material behind.
• Small-scale and artisanal mining: Small-scale and artisanal miners use portable and modular diamond washing plants. They may employ mobile diamond washing plants for gem quality diamonds or stationary plants for industrial-grade diamonds. This flexibility allows small-scale miners to adapt to varying production levels and changing mining locations.
• Recycling and waste management: A diamond recycling washing plant can extract valuable diamonds from industrial waste and water through a process of sedimentation, filtration, and separation. The treated waste is then responsibly disposed of, while the recovered diamonds are recycled into production processes.
• Laboratories and research facilities: Laboratories or educational institutions may have a small-scale diamond washing plant for research, testing, or training purposes. In this case, the plant will have features like efficient water management systems, advanced separation technologies, and safety mechanisms. The diamond washing plant will also comply with industry standards and regulations.

These are just some of the many application areas for diamond washing plants. Their significance cannot be overemphasized, as they remain an integral part of diamond mining companies' and miners' operations.
