This article reviews the use of amalgamation in artisanal gold mining (AGM) and the barriers to reducing mercury use and emissions from the sector. In 2012, AGM accounted for approximately 12% of all the gold produced in the world. The main method of

Conventional comminution (crushing and grinding) uses compressive forces to initiate and propagate cracks throughout the rock mass, yet the material actually breaks under tension since this strength characteristic is about 10 percent of the compressi

In 2006, an unprecedented atmospheric confined space accident took place in a sampling shed at the Sullivan Mine in Kimberley, British Columbia. This accident suggests that a risk assessment should be carried out on a regular basis at mine reclamatio

Hybrid Electric Vehicles improve fuel economy by taking advantage of the Internal Combustion Engine (ICE) peak efficiency operating envelope and using an energy storage system to supply drive power when the ICE has lower efficiency. To achieve this,

Driverless haulage trucks have recently been developed for open pit mines. To predict the benefits of an Autonomous Haulage Truck (AHT) system, a deterministic/stochastic model has been created to compare an AHT fleet with a manual system by estimain

In mining operations, comminution processes are responsible for most of the energy used during mineral recovery. Low fragmentation efficiency of comminution in the range of 1–2% ( Tromans, 2008 ) occurs due to the quasi-static nature of the process

Our world is controlled by the Darwinian principle of survival of the fittest. In the causal equations of events, peace is a "trivial solution" that becomes lost, like a needle in a haystack, among war-bound "general solutions." To find peace, we pro
