The final pit design in open-pit mining is a complex optimization process influenced by geological, economic, geotechnical, operational, and environmental factors. These elements collectively determine the pit’s boundaries, slope stability, profitability, and long-term viability. Below are the key determinants: Geological ...

Simply put, pushbacks are a sequence of controllable stages that can be exploited with the mining equipment currently in use and that can satisfy operational and geotechnical mining constraints. In the design and optimisation of open pit mines, pushbacks are ...

In open-pit mining, the inter-ramp angle refers to the angle of the slope between two consecutive ramps or haul roads, encompassing multiple benches.  The overall slope angle (OSA) is the angle measured from the toe of the pit wall to the crest ...

Pueblo Viejo, the Government of the Dominican Republic, and representatives of affected communities have held dialogues in recent months, mediated by the Public Defender and observed by the Catholic Church. This “Commission” was convened to address outstanding issues linked to ...

Rio Tinto is investing CA$7.6 million in an industrial demonstration project to assess the integration of an ore sorting technology at its Lac Tio mine located in Havre-Saint-Pierre. The Government of Quebec will contribute CA$2.5 million to this initiative through ...
