Concentrating process: rotary mixers, agitators, jigs, cyclones, cones, heavymedia separators (industrial mining only) are used to achieve density separations. Collecting diamond process is done using grease table or xray separators. Final separation and sorting is done visually.
As it turns out, mining for diamonds is one of the most resourceheavy and timeconsuming processes that companies have to invest their efforts in. Even with all our technological advances and engineering tools, diamond mining still incorporates a certain level of art and science combined.
The term, Alluvial Mining is based from the Latin word of "Alluvius" – which roughly translated means "to wash against".This provides a better understanding of the actual process of alluvial diamond mining which is done in riverbeds and beaches where diamonds have been washed out of their host rock and transported by erosion.
From mining to selling, diamonds pass through many hands, not all of them honest. Unless the diamond you purchase is from a Canadian mine or is labcreated (we''ll get into these options shortly), there is no guarantee is has been ethically sourced.
Blood diamonds (also called conflict diamonds, war diamonds, hot diamonds, or red diamonds) are diamonds mined in a war zone and sold to finance an insurgency, an invading army''s war efforts, or a warlord''s activity.

The most commonly used form of extracting diamonds is described by the American Museum of Natural History as open pit or open cast mining. To begin this extraction technique a pit is created; it is dug with steep sides to create a cone narrowing to a point that is connected by roads built into large mines.
The process of diamond creation begins 100 miles underground where tremendous heat and pressure crystallize carbon into rough diamonds ... Pitmining is the most common way to recover diamonds.

Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery. These systems are based on the property of diamonds having a much higher specific gravity (density) of ~ g/cm3 compared to most of the other minerals that make up material in which diamonds are found.
Mar 20, 2017· On average, it can take five months for a diamond to be processed from deep underground to a beautiful diamond ring.

Alluvial mining – mining diamonds from small alluvial diamond deposits that end up in rivers. Marine diamond mining – It is the latest diamond technique that involves the use of vertical and horizontal drilling into the ocean floor to extract diamonds through highly advanced equipment.
There are two main methods of mining diamonds. The primary method is pipe mining; the secondary is alluvial mining. Pipe diamond mining process. Magmas containing diamonds generated by volcanic activity cooled to form diamondiferous cores or "pipes" in the earth. Pipe mining is like the process for mining coal underground.
Jan 14, 2019· The difference is that when shatter nucleates, it generally doesn''t form crystalline structures, at least not ones that you can see. But using a simple process sometimes called "jar tech" or "diamond mining," you can create large crystal formations using little more than time.
Marine mining involves extracting diamonds from the seabed, hundreds of meters under water. The earliest form of marine mining entailed shore diving, where a swimmer would collect diamond bearing gravel from the shallow seabed. Today technology has evolved to specialised ships that mine for diamonds deep out at sea.
Aug 27, 2018· Diamond Mining can be done with cured resin, but live resin more readily lends itself to the process. As with all extraction, starting material is the key to everything that follows, and there are no short cuts or workarounds when it comes to this step — get the loudest, most potent cannabis available.
