During three years of operation the company excavated 360000 tonnes of ore and 940000 tonnes of waste rock before abandoning the mine in 1966. It was a small mine high up in the mountain disturbing an area of only 13 hectares. But it left behind a toxic legacy that has spread far beyond the mine’s perimeter. After 1966 the coho escapement declined steadily from 15000 to a low of 14 in

Dewatering and processing tailings with centrifuges

Mining companies store the dewatered sludge on the ground. This complies with statutory regulations in most countries. In hard-to-reach and confined storage regions or in earthquake-prone areas it is particularly advantageous if the tailings have been dewatered. This minimizes environmental risks and space requirements. The cleaned process water can be recycled. Mine operation costs are

The Role and Importance of Geotechnical Engineering for a

The value of open pit mining operation is primarily driven by ore vs. waste strip ratio. The less waste to move to extract ore the higher the revenue that open pit mine generates. Open pit slope geometry or slope angles is at the core of mine design it is determined based on rock mechanics principles by geotechnical engineers. It is in their custody to design stable slopes to produce the

Mining industry can use waste to fuel operations - Averda

Averda can assists mines with their waste handling and disposal or to set up waste-based fuel operations on-site. Plastic waste or chemical-based refuse can be converted into an alternative fuel source to power furnaces or generators. Organic waste that is combustible can also be a sustainable alternative to diesel. These solutions come with the added benefits of reducing carbon dioxide emissions and being cheaper than fossil fuels.
