Optimising paste production: understanding mixer configuration options When making high solids paste backfill for underground operations, consistent material quality is critical and influences pipeline flow, structural stability, and cost-effective binder utilisation. Choosing the right mixing strategy is therefore a key operational decision.SIMEM offers multiple configurable approaches for paste production: a single large twin shaft paste […]

Optimising cemented paste backfill through admixture technology: improving pumpability, stability and binder efficiency Cemented paste backfill (CPB) has become a key enabling technology in modern underground mining. By returning tailings underground as structural fill, CPB improves stope stability, reduces the environmental footprint of surface tailings storage and provides greater operational flexibility in increasingly complex geological

Designing waste for value: coupling ore sorting with commingled tailings and mine rockfill The mining industry has a growing interest in evaluating pre-concentration (e.g. ore sorting) and commingled tailings as separate innovations, yet both are often constrained by conventional flow sheet design and project evaluation methods. When implemented early in the value chain, ore sorting

Intelligent global navigation satellite system solutions for slope stability monitoring: millimetric precision and multi-tiered averaging to mitigate lag in open cut mining Slope stability in open cut mining faces mounting pressures from deeper excavations and global mineral demands, elevating risks to personnel and productivity. Recent incidents of slope failures at mining operations in Turkey and

Responsible risk-informed tailings closure planning: a Klohn Crippen Berger perspective This article explores Klohn Crippen Berger’s (KCB) perspectives and leadership in responsible tailings closure – examining industry-wide challenges, perspectives on ‘safe closure’ defined by the Global Industry Standard on Tailings Management (GISTM), and the unique opportunity for mining to rebuild trust and leave a lasting,

Testing new ground: how Victoria’s Mine Land Rehabilitation Authority is reimagining post-mining transitions Introduction The Latrobe Valley in Gippsland, Victoria is located approximately 150 km east of Melbourne. It is home to three of the Southern hemisphere’s largest open cut brown coal mines; Hazelwood, Yallourn and Loy Yang, which have powered the state’s electricity sector

The following is an article by Michelle Kiejda, Dave Clark, GHD which was published in the Mine Closure 2024 supplement. Creating lasting impact through sustainable asset transitions Closing major mining assets can heavily affect regional communities, often resulting in job losses, fewer services, and a drop in population. Today, mining companies are expected to handle
