Diamond Mining Process

Pipe mining is like the process for mining coal underground. The “blueground” (a term used to describe the earth in which diamonds are formed) is crushed and flushed with water as it moves on conveyor belts through tubes. Once the diamond-bearing matter is washed, it is dropped onto greased belts.

The 5 Main Steps in Processing Diamond Ore

The heavy minerals, including diamonds, are separated from waste material based on their density differences in a dense media separation process. In this process, ore is mixed into a ferrosilicon slurry, then fed to a dense media cyclone, where the heavy minerals are separated from the waste. The heavy minerals sink and exit the bottom of the cyclone to a sinks screen, and the waste floats and exits the

How Are Diamonds Mined And Extracted From

To make mining efficient and effective, the raw rock and soil are typically not examined on-site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.

How diamond is made - material, history, used,

Diamonds are mined either from the kimberlite pipes below the earth's surface, or from alluvial deposits. Alluvial (riverbed) deposits occurred when volcanic action carried kimberlite and other minerals from the center of activity to naturally forming irrigation systems. Such diamonds are found quite near the earth's surface. In alluvial mining, considerable amounts of sand must first be removed from the area. The

In a Dense Media Separation (DMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond bearing material is added to begin the separation process of the heavier minerals from the lighter material. Additional separation of the denser material occurs by centrifuge in “cyclones” that swirl the

This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise
