About DeepMind

When we started DeepMind in 2010, there was far less interest in the field of AI than there is today. To accelerate the field, we took an interdisciplinary approach, bringing together new ideas and advances in machine learning, neuroscience, engineering, mathematics, simulation and computing infrastructure, along with new ways of organising scientific endeavour.

The environmental impact of the Robinson Deep mine residue

The presence of melanterite thus suggests that oxidation of sulphides is an ongoing process on the Robinson Deep mine residue deposit. Evaporation of water in the evaporation ponds aids in increasing the concentration, hence allowing the predominant precipitation of jarosite group minerals.

Methods of Gold Mining Geology In

South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson Deep, at that time the deepest mine in the world for any mineral.
