Application of FTA Analysis for Calculation of the Probability of the Failure of the Pressure Leaching Process

European Union legislation requires organizations to assess their processes in the context of risk management. The main task management is manage all risks that can significantly affect outcome processes. article focused on evaluation pressure leaching at elevated temperature using method Fault Tree Analysis (FTA). effectivity pyrite and arsenic decomposition by oxidative influenced duration process, temperature, concentration solution a density slurry. It was found that, under equitable conditions, decomposes more intensely than pyrite. Under laboratory performed an autoclave. Due aggressive environment, increased process failure possible. Its probability calculated FTA. has been top event examined disproportionately high (0.057) represents invitation take corrective actions. Monte Carlo used for simulation effect basic events event—the process.
