Kimberlite is an igneous rock that major source of diamonds.Kimberlite is a variety of peridotite.It is rich in mica minerals content and often in form of crystals of phlogopite. Other containt abundant minerals are chrome-diopside, olivine, and chromium- and pyrope-rich garnet.Kimberlite is typically found in pipes – structures with vertical edges that are roughly …
Blasting kimberlite mining is a device in the form of a plane shavings thickness of 0.1-0.3 m on the entire height of the layer under the guise of powered roof supports.

kimberlite Mining is an important part of the equation in diamond's value. Specifically, mining is the process of first locating and then extracting the rough. Of course diamond mining could be as easy as stooping over and digging up a large, fine, …
FIELD: mining. SUBSTANCE: formation mining method of kimberlite pipe involves mining of ventilation, bottom and sectional gangways, ventilation and filling raises, ore chute, formation mining and stowing operations. At that, each formation is divided in horizontal plane into several sections with equal equivalent roof passage.
The process of exploring for diamonds is actually exploration for the host rock that carried the diamonds to the surface – kimberlite. Kimberlite is a volcanic rock that occurs in diatremes, or narrow volcanic "pipes". It may also occur in vertically oriented narrow sheets, or dikes. Once a kimberlite is found there is no guarantee that ...
Here we present an improved, rationalised and staged approach to kimberlite terminology and classification. The practical and systematic framework, or scheme, is intended to assist in the description, recognition and understanding of the complex and unusual rocks encountered during diamond exploration and mining.
FIELD: mining; applicable in crystal-saving technology of diamond mining in working of permafrost kimberlites under extreme conditions of the North. SUBSTANCE: mining of kimberlite pipe is carried out under crystal- saving conditions by separating of rock mass into elementary blocks with help of shaped charges; breakage of separated blocks by high …
Read more about mining in South Africa. A total of six holes were drilled in the Thorny River area. A combined total of 39.5 m intersected kimberlite while an additional 55 m intersected a weathered kimberlite breccia. The best hole contained a down-the-hole (at forty-five degrees dip) intersection of kimberlite and kimberlite breccia of 19 m.
The Mothae kimberlite mine is situated at an altitude of 2,900m above sea level in the Maluti Mountains of Lesotho. It is located 5km away from Letseng diamond mine and 135km from the capital city of Maseru. The mine can be accessed from Butha-Buthe by a tar road which is approachable through a 5km-long gravel road. Geology of Mothae kimberlite
Kimberlites. The first Kimberlites were described by Vanuxen in 1837 from Ludlowiville near Ithaca, New York state; however, the term Kimberlite was introduced by Lewis (1887) to describe the diamond-bearing, porphyritic mica peridotites of the Kimberley area of South Africa. Kimberlites are highly magnesian (MgO > 25% weight) magmatic rocks ...

At this stage only the diamond prices and operating costs for the current year are applied. Whittle mines the pit as if the
Mining is an important part of the equation in diamond's value. Specifically, mining is the process of first locating and then extracting the rough. ... Kimberlite pipes exist all over the world but very few actually contain diamonds. Even when they are diamond bearing, the pipe has to be rich enough to justify the major expense involved in ...
Use of kimberlite tailings In detergent. The present invention provides a process for the preparation of detergent builder Zeolite-A from Kimberlite tailing generated as solid waste during diamond mining is disclosed. The process comprises, reacting an acid treated Kimberlite tailing with alkali solution to obtain sodium silicate and reacting it with alkaline aluminum source at …
kimberlite breccia or TKB. The root zone is composed of magmatic or hypabyssal material usually porphyritic in appearance, containing macrocrysts of olivine and phlogopite set in a fine-grained matrix, often with xenocrystic garnet, ilmenite, spinel and chrome-diopside. Mining difficulties may be experienced in the hypabyssal
THE Zimbabwe Consolidated Diamond Company (ZCDC) has invested $30 million in kimberlite mining and plant equipment from South Africa in a bid to exploit minerals for sustainability and growth. Of ...
Previously known as Gope mine, Ghaghoo is an underground mining operation mainly focused on extracting diamond ore from the GO25 kimberlite pipe. The mining license for Ghaghoo mine was obtained in January 2011 and construction commenced shortly after. The mine was officially opened in September 2014. It is expected to have a production ...
Kimberlites form this region do yield beautiful diamonds which mostly range from very small to a maximum of 3 carats. Customers have found 1/4 carat to 1/2 carat blue diamonds and yellow & clear diamonds between 1/4 and 2 carats within …
Mining narrow kimberlite dikes to great depths always has been a challenge for diamond miners. Up to now dikes are mined manually by small scale drill and blast operation, supported by hydraulic jack hammers and small excavators. Mining dikes require high manpower utilization at overall low production rates and significant safety hazards.
