RTB 'Bor' invested 25 million EUR into new electronic equipment in Veliki Krivelj flotation

Mining basin 'Bor' has invested 25 million EUR in new technology, reconstruction and expansion of one of the most significant plants for copper processing, the flotation in Veliki Krivelj. Now, the entire process of manufacture can be monitored and regulated electronically and with the help of cameras.
Due to savings on expenses for reagents and electricity and expansion of capacity, the invested money should be returned in 5 years period.
- For the purchase of equipment from 'Meco minerals' was given 17 million EUR, and entire value of the project is 25 million EUR. This investment allows us to cut down expenses, primarily of electricity, and with that we have increased the quantity and the quality of copper concentrate for the new plant. Once we finish reconstruction we will have a completely automated process, stated Veliki Krivelj flotation manager, Vesna Pavlov.
More than 90% of works have been completed, the capacity has been increased from 8 to 10 and a half million tons of mine per year, and once all the work is done, the capacity should reach the planned 18 million tons of mine.
Electronic process management has been implemented, and from the control room it is possible to monitor and regulate the manufacture.
-Cameras are directed into the chamber of flotation machine and from the command room we can see exactly the look of the copper foam, if the flotation machine is discarding more or less material and based on that we can regulate the level within the machines and reagents that we use. In this way, it is a lot easier to run properly the entire technological process, explained Pavlov.
