Mining extraction and processing of mineral resources traditionally takes place within individual disciplines or organisational units that are separated from each other. These units are partly separated from each other by hard physical or virtual interfaces and are typically incentivised by their own performance metrics. Geometallurgy strives to network the knowledge from the individual disciplines. […]

Sampling solutions

All decisions in process development, mine planning and process optimisation are based on analytical results. However, analytical results cannot be separated from the specific conditions under which they were obtained. Sampling comes to the fore as a critical success factor before analysis, which should only be carried out on documented representative samples as a basis […]

Dry mineral processing

Dry processing can make an important contribution to reducing water consumption. One possibility is sensor-based ore sorting, but density separation, magnetic separation, crushing and classification processes are also options that can be considered for the ore in question. Case-by-case consideration is essential here, as dry processes often have cost advantages, but will only result in […]

Physical Separation

What are the right extraction and benefication processes for a specific ore? Understanding the value proposition of mineral production value chains and the heterogeneity of a particulate bulk material form the basis for selecting the right processes and equipment. Physical separation is historically the oldest separation process, apart from hand-picking. The most popular reference is […]
