Innovation plays a critical role in the mining industry as a tool to improve the efficiency of its processes, to reduce costs, but also to meet the increasing social and environmental concerns among communities and authorities. Technological progress has also been crucial to allow the exploitation of new deposits in more complex scenarios: lower ore grades, extreme weather conditions, deeper ...
Xstrata.9 In Ghana alone, approximately 23 mining companies are active, including global leaders such as AngloGold Ashanti and Newmont. The government holds a minority (10 percent) free carried interest in most of the main active large-scale mines. Over the past 10 years, Chinese mining companies also have become important players in the region.

Why mining is done so deep in the ground? Underground mining is used for ores that are deep in Earth's surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. These methods are more expensive than surface mining because tunnels are made in the rock so that miners and equipment can get to the ore.
