The present work reports a proposal for the restructuring of the discipline of Control Systems I for undergraduate students of Control and automation engineering of UFMT. The discipline followed the traditional learning model and the new proposal contemplates the project based learning (PjBL). The objective of this experiment is to motivate students to become more central to the solution of real engineering problems, developing functional prototypes throughout the course. It is concluded that the applied proposal has great potential as a learning method and can also be applied in other engineering disciplines that involve theory and practice, since it increases the students' involvement with the project since their beginning. The idea was highly accepted by the students and the authors suggest questionnaires that evaluate students' learning to reduce traditional classes where the teacher was the sole source of knowledge and increase the students' active behavior.
All scientific knowledge must be constructed based on its impact on society; and one of the ways to work this critical- thinking on engineering students is through extension practice. The present paper evaluated - through a questionnaire - 20 students who participated in the Education, Geoscience and Mining extension program of UFMT whose participants are graduates in mining engineering or geology. In this evaluation the questions asked involved themes such as the student's interest in the course and university before and after the project, if they participated in any scientific event during the extension, if they are more prepared to discuss questions about their profession after the project, among others. As a result, those who were part of the program are more inserted, adapted and prepared to speak in public about the themes they worked on than before. It is concluded that the critical formation of the engineering student is enhanced when it is associated with a contextualized practice. The university extension project allowed mine engineering and geology students to reflect on the impact of their future profession.
The greatest and noblest challenge of mining engineering for the present and the future of iron ore treatment could be considered as the pursuit of optimizing the use of mineral resources. The use of mining tailings, in the mineral sector itself, or in another industrial branch, meets the needs of circular economy as it increases the useful service life of this material. In order to investigate this scenario, a technological characterization of a sample from a tailings dam was carried out along with magnetic concentration tests in a Wet High-Intensity Magnetic Separator (WHIMS) to propose a possible concentration route. In relation to the characterization itself, the results demonstrated a relative density of 3.04 x 10 3 Kg/m 3 and an average superficial specific area of 3.75 cm³/g. The granulometric analysis classified the material as fine, with d 90 of 0.110 mm and d 50 ≅ 0.049 mm. Quartz, hematite, goethite, kaolinite and manganese oxide were identified in the sample. The test which presented the best results (66.83% Fe and 1.74% SiO 2 ) consisted of the Rougher, Cleaner and Recleaner phases, using a 1.5 mm grooved GAP matrix, a 7,000 Gauss magnetic field, 30% solids, and water pressure at 0.5 kgf/cm 2 (49.0 x 10 3 Pa). Finally, the conclusive results indicate that the studied material can be concentrated through magnetic concentration, keeping in mind the specifications concerning the pellet feed fines commercial product. Besides the financial gain, the activity prolongs the durability of the tailings dam and reduces the environmental impacts associated with these structures.
Resumo: Todo saber científico deve ser construído pensando no seu impacto na sociedade; e uma das formas de se trabalhar esse pensamento crítico em alunos de engenharia é através da prática de extensão. Entretanto, a pandemia da COVID-19 trouxe diversos desafios para a academia. Um deles foi a necessidade de reestruturação dos projetos de extensão, uma vez que a Organização Mundial de Saúde recomendou o isolamento social para diminuir o contágio pelo vírus. Dessa forma, o presente artigo relatou as adaptações realizadas em ações do projeto de extensão em Educação, Geociências e Mineração, o evento intitulado MineraFérias,
