White paper: Portland-limestone cements in paste backfill – performance limits and hidden environmental costs
This paper re-assesses the role of Portland-limestone cements in cemented paste backfill by reviewing underlying mechanisms, published performance data, and environmental implications.
Designing High-Performance Paste Backfill Systems at MMG Khoemacau Zone 5
In this technical article, we look at the design of the paste backfill system for MMG Khoemacau Zone 5 Mine, where long paste reticulation distances, high-pressure pumping requirements, and ultra-fine tailings presented a number of engineering challenges.
Micro paste: producing paste backfill utilising ultra-fine copper tailings
This paper compares three case studies that explore test work on ultra-fine copper tailings with a significant micro-sized fraction, providing insights into the solutions for achieving effective paste backfill in these new mining environments.
Optimisation of cemented aggregate backfill at New Luika Gold Mine
This paper presents a case study of an optimisation of a CAF material by the addition of tailings in order to increase the paste fraction of the material. The main aim was to decrease the angle of repose to improve filling ability in addition to decreasing the required binder content.
