Estudo de caso sobre a corrosão em uma planta de extração de ouro

Abstract

Considering the impacts of corrosion on the world industry and the importance of its understanding for its control and prevention, the present work was proposed to identify its main causes and thus propose solutions for a gold extraction company. It is an applied study that joined exploratory and descriptive objectives, where through a qualitative approach, it joined case study and bibliographic research to conduct the study, producing data in the form of observations, interviews and the climate. From this, the presence of weathering corrosion was shown due to the proximity of the sea and the action of the winds. Thus, the presence of rain and its influence on the values of relative humidity of the air, together with the variation in temperature between day and night, constitute aggravating factors for weathering corrosion in the studied place, in addition, there were geometry, galvanic cell and crevice problems. From this, solutions were proposed in the form of mitigating actions for each situation, leading to the conclusion that despite the severity of the observed climate, a set of measures can minimize the effects of corrosion.
