Abstract:
In mining, the formation of scale is a constant and inherent challenge in the most varied mineral processing operations, directly affecting the unit operation related to the problem, be it reducing the efficiency of pumps and pumping systems, filtration processes, pipes in general, evaporators and heat exchangers among others. Specifically in this Case Study (Iron Ore Processing Plant located in Brazil) the ScaleTrol PDC 9325 program was used as a way to control and inhibit the constant formation of scale, mainly formed by calcium carbonate and iron oxide in the washing system of gases (precipitator tank), which significantly reduced the physical availability of the system, overloading the circuit and causing interruptions and unscheduled stops for unblocking, cleaning and/or changing pipes
