Abstract: Increasing the design capacity of three-stage crushing and two-stage sieving from 8.5 x 106 t to 10.6 x 106 t of wet ore annually in the Flotation Plant Veliki Krivelj of RTB Bor with the upper size limit of final crushing product of 100 (%) - 16 mm lower than the previous one, the designed upper size limit of 100 (%) - 20 mm, according to investor demands should have to be done with the available equipment and existing technological scheme of mineral processing. By detailed analyzing the operation and crushing product of this plant, the bottlenecks in the existing processes of crushing and sieving were registered and, in accordance with them, the adequate solutions for achieving the defined objective were proposed: 'Increase the capacity of wet ore processing to Q = 10.6 x 106 t/annually with the upper size limit of 16 mm', with as low as possible the investments, that is with the existing equipment and according to the existing technological scheme of processing. This paper presents a part of operation analysis of the aforementioned plant with a proposal of technical solutions that can lead to the realization of set conditions and achieving the capacity of crushing and sieving plant in the copper mine Veliki Krivelj Q = 10.6 x 106 t of wet ore annually with the upper size limit of 100(%) - 16 mm.
