The Operational Model

The OPERATIONAL MODEL is a process engineering compendium that has been developed by Alexis Yovanovic since 1987 for several mineral processing mechanical operations. It establishes an analogy with chemical processes creating a new phenomenological interpretation for both the Comminution and the Concentration with Mineral Particles Transfer. The Operational Model defines how mineral particles would behave if they were molecules, always guiding them along the shortest path, just like the GPS for a driver.

MOPENEWS, the MOPE newsletter, has been distributed to the mineral segment for many years and, currently, turned into almost mandatory reading for several subscribers around the world, especially in Brazil, Chile, the USA, Canada, Australia, Europe, and Latin America.

The Creativity and the Riskㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Whoever develops creative solutions, whether manufacturer, employee or consultant, deserves merit. Many of such solutions, however, will never turn into reality in industrial operations due to the […]

Tailings: The new normal?ㅤㅤㅤㅤ

In a situation of scarcity of new mining projects, the major suppliers of machinery, spare parts, and inputs bet their chips on the reprocessing of the tailings. […]

Women in Miningㅤㅤㅤㅤㅤㅤㅤ

For historical reasons, which fortunately are in a gradual process of transformation, the participation of women in mining (as well as in other technical professions) is still […]

Upcoming Events

Updated calendar with the main events in the mining sector during the year 2021.

O fórum é constituído de conferência magna, plenárias, sessões técnicas, workshop, debates, apresentação e premiação de trabalhos técnicos relativos à mineração. Além disso, também é oferecido um espaço para exposição de marcas, produtos e equipamentos por parte dos patrocinadores.

Entre as principais finalidades do evento está a promoção de um intercâmbio de ideias entre estudantes, professores, pesquisadores, autoridades, executivos e profissionais ligados ao setor mineral. A principal ideia é que os interessados apresentem publicamente novas proposições e abordagens para evolução constante da atividade mineral brasileira.

28 e 29 de abril de 2021
