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.

Water management is increasingly becoming a strategic business imperative within boardrooms across international mining organizations.

Water management is integral for mining success and for building a sustainable business. Investors, communities, governments and other industries are demanding that mining companies become more efficient at water reuse and water management.

The result is that water stewardship practices are more prevalent than ever before and that mining companies are working closely with communities to better access, preserve and treat water.

The 2020 Water in Mining Digital Conference brings together water management leaders from the top 50 global mining companies to network, debate and discuss the present and future of water in mining.

Nowhere else will you meet a higher concentration of senior influencers who are shaping the future of water in mining. Join us to weigh in on the debate and to explore the innovative treatment processes that keep costs low and benefit the natural environment.

We look forward to meeting you online for this unrivalled opportunity for networking and knowledge exchange.
