Reducing GHG by hydro power and optimisation of

2021-5-20  There is an intense focus on optimisation of haulage conditions and driver training as these produce fuel savings, cost reductions and reduced emissions. Route optimisation work at the Bald Mountain mine in Nevada has saved more than 15,000 hours of haulage time since January 2017, while at the Fort Knox mine in Alaska time savings of over 10% have been made on every haul truck cycle

Development of ECO-UHPC utilizing gold mine

Pyo et al. (2018) used a type of quartz-based mine tailings to partially replace (30% by mass) quartz sand in UHPC, and obtained strength comparable to that of the UHPC with 100% quartz sand. Research addressing the influence of utilizing gold mine tailings, as quartz sand alternative, on the properties of UHPC is scarce in the literature.

Alamos Gold Operations Development Projects

Ağı Dağı is expected to produce an average of 177,600 oz of gold at mine-site all-in sustaining costs 1 of $411/oz over a six year mine life. Mineralized material from the nearby Çamyurt deposit is expected to be trucked and processed at Ağı Dağı after it has been depleted, resulting in a combined mine life of nearly 10 years between the two projects.
