New stage of technical re-equipment at AGD DIAMONDS

09 december 2019
The completed technical re-equipment of the concentration plant at the Grib Mining and Processing Division made it possible for AGD DIAMONDS to increase the quality of recovered diamonds while preserving all the production targets.
In 2019, AGD DIAMONDS re-equipped its concentration plant having commissioned six units of additional equipment at the ore preparation site (the place for final crushing of heavy-medium-separation tailings) to reach its diamond mining targets and maintain the productive capacity of the concentration plant in the period when diamond ore will end in the crater part of the Grib mine and processing will be switched over to ores with higher strength characteristics (kimberlite, xenotuff breccia). It is the first time in Russia, when modern, intelligent and compact ThyssenKrupp crushers are used for ore concentration.

The technical re-equipment of the company’s concentration plant allows it to maintain the design productivity of the Grib Mining and Processing Division increasing the processing of the most durable kimberlite ores up to 65%, which ensures the planned annual diamond production of AGD DIAMONDS. At the same time, this improves the safety (integrity) of large special-sized diamonds (10.8+) due to lower technological impact during processing. Thus, in 2018 the share of undamaged diamonds (without scratches, chips or cracks) recovered by the company amounted to 51.19%, while in the 11 months of 2019 this figure went up to 69.83%.
The first step to modernize the concentration plant at the Grib Mining and Processing Division was made by AGD DIAMONDS in the end of 2018 and it was the commissioning of the latest diamond processing equipment, the COM Tertiary XRT 1200 / D separator manufactured by TOMRA. As a result, the company produced over ten exclusive diamonds, each of them weighing more than 50 carats. These included four diamonds weighing more than 100 carats. In particular, AGD DIAMONDS extracted two unique diamonds weighing 222.09 and 127.34 carats in May and one diamond weighing 212.53 carats in July. In October, the company recovered an exclusive gem-quality diamond weighing 104.12 carats.
