Once a diamond operation yields ore, the diamonds must be sorted from the other materials. Excavated ore is transported to a processing plant. The kimberlite is first crushed and then processed through the plant, which consists of a series of screens, jigs and scrubbers and a gravity pan or DMS plant to remove lighter particles and create a ...
At the heart of the framework for innovation is Design Council's design methodology, the Double Diamond – a clear, comprehensive and visual description of the design process. Launched in 2004, the Double Diamond has become world-renowned with millions of references to it on the web.
Designed in the 1950s to make the diamond industry more lucrative, the process of creating high-pressure high-temperature (HPHT) diamonds is actually having a negative impact on today's industry. HPHT diamonds are less expensive than their natural counterparts and develop a significantly better color after undergoing this process. Companies purchase cheaper, less desirable diamonds, put them ...
Before a diamond is even processed, it must be mined first. The mineral is recovered from ore through a process known as comminution and liberation. Comminution is the breakage of larger ore into smaller particles. The liberation is the process of removing the incorporated diamond .
How Are Diamonds Cut And Polished From Roughs? Diamond cutting is the process that takes a rough diamond and changes it into a shaped and beautiful gem. The process must be undertaken by a professional with expert knowledge, equipment and tools for the job since every single decision made will affect the outcome of profitability.
A diamond is marked in order to determine how it may be cut to the greatest advantage. Traditionally, an experienced diamond expert used an Indian ink pen to do this. More recent methods involve computer-aided design systems that analyze the stone, and then mark their surface using a .
Concentrating process: rotary mixers, agitators, jigs, cyclones, cones, heavy-media separators (industrial mining only) are used to achieve density separations. Collecting diamond process is done using grease table or x-ray separators. Final separation and sorting is done visually.

Jul 18, 2008· Learn about the diamond manufacturing process from the mine to market.
Next, a gravity-based device is used to sort the diamond-containing portions—called the concentrate—from the tailings, or the filler rock. One of the most commonly used methods to separate the two is a type of washing pan developed in South Africa in the 1870s.
Diamond crystals grown in these manufacturing processes inherit characteristics of the manufacturing process that can be used to tell them apart. These characteristics can also be used to separate them from natural diamonds. Some lab-grown diamonds can be separated from natural diamonds by a trained gemologist using standard tools.
A typical HPHT diamond-creation process goes something like this: If human hair or ashes is being used for the process, the carbon is extracted from the sample and placed on a diamond-growing foundation. The mixture is placed in the center of a HPHT machine. This complex machinery creates diamond-growing conditions found deep within the Earth.
Diamond tools are regularly used in the manufacture of optics, such as mirrors and lenses, as well as other glass drilling applications. In abrasive machining processes, diamond abrasive wheels are used in the sharpening of various other cutting tools and in the dressing of other grinding wheels.
Processing Methods. Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.
Final Recovery Methods. After processing the diamond bearing material in to concentrated form, final recovery of the diamonds is done by taking advantage of two further unique physical properties of diamonds – that they are hydrophobic, and that they fluoresce when exposed to x-rays.
Jul 28, 1992· The process can be used before and/or after cutting and polishing the diamond.
