Productivity in mining

The mining industry spends very little on research and development for innovation compared to other sectors, especially on mining and processing methods In fact, the last major investment in process technology was back in the 1970s when mining was booming and the Australian mining industry invested in gold extraction process.

11 PHASES OF A MINING PROJECT

1133 Underground mining In underground mining, a minimal amount of overburden is removed to gain access to the ore deposit Access to this ore deposit is gained by tunnels or shafts Tunnels or shafts lead to a more horizontal network of underground tunnels that directly access the ore In an underground mining method called ‘stoping’ or.
