Appropriate selection of rheological models is important for hydraulic calculations of pressure loss prediction and hole cleaning efficiency of drilling fluids. Power law, Bingham-Plastic and Herschel-Bulkley models are ...

Damang Gold Mine (DGM) in Ghana uses open pit mining technology to mine its gold deposit. It has an estimated mineable gold reserve of about 32 Mt exploitable for 8 years. As the gold price kept falling from 2013 and ...

This work presents prediction and optimisation of controllable parameters of drilling and blasting currently used at the Fobinso Pit of Perseus Mining Ghana Limited (PMGL). The mine faces challenges with blast particle ...

High cost of metric photogrammetric cameras has given rise to the utilisation of non-metric digital cameras to generate photogrammetric products in traditional close range or terrestrial photogrammetric applications. For ...

Coconut shells are used as precursors for preparation of activated carbons. The shells could vary in terms of their maturity. The influence of the maturity of the shells on gold adsorption efficiencies of derived activated ...

The increasing exploration and production activities in the offshore Cape Three Point Blocks of Ghana have led to the discovery and development of gas condensate fields in addition to the oil fields which produce significant ...

Gypsum exists in the Dihydrate (CaSO4 2H2O), Hemihydrate (CaSO4. ½H2O) and the Anhydrite (CaSO4) forms. The exploitation of the natural rock form deposit of gypsum is on the increase, necessitating the need to find ...

Rainstorm intensity–duration–frequency relationship is a tool required for appropriate planning and designing of drainage systems. In this study, 22 years of annual peak daily rainstorm data distribution was tested to ...

Cadastral surveys in Ghana often employ well known surveying equipment such as Total Station and GNSS receivers or a combination of both. These survey techniques are well-established and widely accepted. However, there ...

Arsenic (As) has the potential to negatively affect soils and groundwater quality, and cause several public health challenges. It is usually concentrated and released during metal mining of ores that contains arsenic-bearing ...
