At the heart of the system lies a scalable, fast, robust mineral sensor suite, utilising high frequency electromagnetic spectroscopy and high speed X-ray fluorescent technologies, in combination with laser telemetry, to measure and report ore grade in real time, and so improve its separation from waste rock.how are diamonds seperated from ore waste rock,Diamond Recovery Methods - Latest News - Ehud Arye LaniadoMar 30, 2016 . Since kimberlite is formed underground, it is a relatively hard rock, similar to granite. The first step to finding the 'needle in a haystack' diamond, is crushing the kimberlite ore. This has to be done in a controlled way in order to avoid breaking or damaging the diamonds trapped inside. Some alluvial mines.

How are waste materials managed at mine sites - Mining Facts Org[1] The soil and rock which is removed to gain access to buried ore, and the material (water, solids, and gases) left behind after the ore has been processed to remove the valuable commodities, are considered to be waste materials. However, the difference in mineral content between ore and waste rock can change.how are diamonds seperated from ore waste rock,Ore sorting - WikipediaOre sorting is separating an ore into constituent parts. Today, ore sorters are widely used in industrial mineral mines, diamond mines and base and precious metal mines. Ores are typically sorted to increase the efficiency of other refining processes, by reducing the amount of material to be processed while simultaneously.
