Large flotation tank cells are one of the recent advances in the field of mineral processing. These cells are believed to provide a significant economic benefit due to a smaller footprint and fewer flotation cells needed for similar duty. However, these cells come with significant challenges, especially around froth transport distance and froth carry rates.
This presentation summarizes the key challenges and recent advances in froth management. Critical operating factors affecting froth stability are reviewed as well as the role of design elements such as crowders and launders that control the froth transport on mechanical flotation cells.
The optimization of the minerals value chain is a holistic approach towards more economically and environmentally sustainable operations. This new toolset uses detailed geometallurgical characterization of the ore domains and concentrator plant models integrated as a digital plant. It simulates the kinetic behaviour of mineral particles in beneficiation processes for each ore type and their blend. It also assesses the most profitable operating scenarios to final payable metal for daily use at concentrator plants.
The main objective of this presentation is to show how the processing of complex ores can be optimized using Mine to Mill modelling.
Dry stacking is one way to store tailings however, it requires that the material meets certain geotechnical properties such as being unsaturated, which is often achieved by using filtration.
This presentation looks at tailings samples to understand how the dewatering properties compare to the geotechnical ones. Trends in the relationship will be discussed and how the tailings characteristics affect these trends.
This analysis aims to decrease the gap between the geotechnical and the process design and to stimulate cross-disciplinary learning. A better grasp of tailings properties can lead to optimized filtration & dry stacking solutions.
