Russian Rusolovo JSC Completes Ore Sorting System Upgrade at Pravourmiysk Mining Area

en.Wedoany.com Reported - On November 12, Russian Rusolovo JSC completed the planned technical upgrade of the modular ore sorting system at the Pravourmiysk production complex in Khabarovsk Krai, increasing the processing capacity of the crushing and screening stage from 1,700 tons per day to 2,200 tons per day, and the processing capacity of the X-ray absorption sorting stage from 1,200 tons per day to 1,600 tons per day. The upgrade was carried out on the existing third modular ore sorting system, and the main production processes were not halted during construction.

The upgrade mainly involved the ore crushing and screening equipment and the X-ray absorption sorting equipment. After the upgrade, the daily processing capacity of the crushing and screening stage increased by 500 tons, an increase of approximately 29.4%; the daily processing capacity of the X-ray absorption sorting stage increased by 400 tons, an increase of approximately 33.3%. The capacities of these two pieces of equipment correspond to the ore pre-treatment and subsequent sorting processes, respectively.

X-ray absorption sorting technology identifies differences in material composition between ore and waste rock, separating ore containing a higher content of useful metals from low-grade waste rock. The pre-sorted ore then enters subsequent beneficiation processes, reducing the amount of waste rock entering downstream processing stages. This equipment upgrade has increased the processing capacity of the front-end crushing and screening and sorting stages, providing greater raw material processing capacity for subsequent tin-bearing ore processing.

The target of this upgrade was the third modular ore sorting system that had already been put into operation. Rusolovo JSC launched the construction and installation of this equipment in 2024. The equipment is equipped with an X-ray fluorescence analysis device for identifying useful components in ore and separating waste rock. This upgrade increases processing capacity based on existing equipment and is not the construction of a new independent sorting production line.
