Diamond Mining and Processing
Diamonds undergo various processes from being extracted from the ground, to those beautiful shiny rocks. Diamond mining involves a combination of art and science, despite all of our modern advancements and engineering equipment available today.
Prospectors must first discover the diamond sources before any actual mining can begin. Geologists do this by tracing the primary sources of pipe deposits by following the path of secondary diamond sources, such as river beds.
Ore samples are then tested to determine acceptability and mining viability after the pipes are located. Once the presence of diamonds is confirmed and deemed profitable, large quantities of soil are removed by inserting shanks into the ground at the ore-bearing pipelines.
Technology:
Ore-processing and Dense Media Separation
When a diamond operation produces ore, it must separate the diamonds from the other material. The mined ore (Kimberlite) is then transported to the processing facility, usually a DMS plant (Dense Media Separation plant).
After being crushed, the Kimberlite is processed at the plant, which consists of a number of screens, jig, and scrubbers as well as undergo Dense Media Separation, to remove lighter particles and produce a concentration of heavy material, which includes the diamonds.
Dense Media Separation is a process that uses gravity to separate particles with higher densities (like diamonds) from particles with lower densities – which is an effective way to extract diamonds from diamond-bearing material. Dense Media Separation is widely used in diamond processing plants around the word, because it s so effective, simple and affordable.
Ferrosilicon is used by mixing it with a liquid to form a mixture of a very specific density, close to that of diamonds. The diamond bearing material is then added to the pulp (inside a separation tank or cyclone), which will then cause the heavier materials to sink, while the lighter materials will float.
Ferrosilicon manufactured by DMS Powders
DMS Powders is a leading manufacturer of Ferrosilicon, specifically for use in the Dense Media Separation of diamonds. DMS Powders produces specialised Ferrosilicon powders for Dense Medium Separation; these powders contain 14% – 16% Silicon (by weight) with a Relative Density of 6.8 – 7.1.
Ferrosilicon manufactured by DMS Powders undergo stringent control of chemical composition as well as physical properties, to offer the following advantages:
- Narrow particle size distribution results in predictable medium behaviour.
- Excellent recovery due to the medium’s high magnetic susceptibility.
- High specific gravity of the medium.
- Low operating expenses because of the medium’s high specific gravity and magnetic recoverability.
