Geomechanical Design For The World’s Largest Underground Mine
Esteban Hormazabal

The Chuquicamata underground mine in the Atacama Desert in northern Chile is one of the largest planned mining projects in the world to use block caving with macro-blocks option to mine copper ore.

Examples Of Typical Errors Detected In Geotechnical Core Logging
Andrea Russo

In the first stages of a mining project, it is a cost saving advantage to collect the geotechnical basic parameters required for the geotechnical rock mass assessment during exploration.

Bioaccumulation Of Heavy Metals In Aquatic And Terrestrial Vegetation Tissues In Areas Of Environmental Liabilities
Lizardo Cahuana and Osvaldo Aduvire

Considering that mining environmental liabilities are those installations, effluents, emissions, remains or deposits of waste produced by old abandoned mining operations that constitute a permanent and potential risk to the health of the population, the surrounding ecosystem, and property.

Direct Extraction Lithium Processes: The Challenges Of Spent Brine Disposal
Ignacio Ezama, Camilo de los Hoyos, Pablo Cortegoso, Terry Braun

The significant role of lithium in the continued development and expansion of renewable and clean energy has led to an increase in the demand for projects involving the extraction of lithium from shallow brines, particularly in the ‘lithium triangle’ – Salar de Atacama in Chile, Salar de Uyuni in Bolivia and Salar de Hombre Muerto in Argentina – to be developed.

Geotechnical Behaviour Of Spent Ore - Impacts Of Metallurgical Factors
Rigoberto Rimmelin and Carolina Vergara

Heap leach pads are composed of mined ore, usually crushed, disposed on liners to be processed with leach solutions, and the tail of the process is called “spent ore” which are then transported by conveyor belts to be disposed into dumps.

Influence Of The Undercut Height On The Behaviour Of Pillars At The Extraction Level In Block And Panel Caving Operations
Esteban Hormazabal, Rodolfo Alvarez, Andrea Russo and Diego Acevedo

Definition of the undercutting geometry and size is an essential aspect of the design of a block and panel caving operation.
