In mineral processing projects, it is crucial ensure the equipment efficiency, highly influenced by the intrinsic\udvariability of ore characteristics. To characterize the ore, laboratory and pilot tests are conducted. Pilot tests are generally\udexpensive, so they are performed only for a few samples. Laboratory tests are cheaper, and, therefore, can be carried out\udusing more samples for better representation of the ore reserve diversity. However, the repeatability of results in industrial\udscale is not defined. In an effort to verify the accordance between these tests and the industrial practices, the results\udof a plant operation were compared to the results of a dynamic simulation, calibrated with data from laboratory tests,\udfor the period of one year. Initially, the plant ROM (run of mine) was tracked. Then, sample mixtures that represented\udits characteristics, such as content and size distribution, were obtained. The plant has screening, magnetic separation,\uddesliming, and flotation operations and laboratory tests are available for the last three mentioned processes. Thus, the\udprocess was simulated, using the real plant downtime, and a control strategy similar to that practiced in the plant, so that\udit was possible to determine a theoretical output that would be obtained if laboratory testing accurately represented\udthe operation. It was observed that there was acceptable conformity in the flotation and desliming process and little\udconformity in magnetic separation
