1.1 PHASES OF A MINING PROJECT - ELAW

1.1.3 Active mining Once a mining company has constructed access roads and prepared staging areas that would house project personnel and equipment, mining may commence. All types of active mining share a common aspect: the extraction and concentration (or beneficiation) of a metal from the earth. Proposed mining projects

Productivity in mining operations: Reversing the downward

The surge in demand for metals and minerals in the early 2000s quickly translated into much higher prices and, with it, much increased miners’ profitability. Boosting production volumes became the industry’s top priority. Mining companies worldwide largely lost sight of productivity goals that had underpinned operating discipline in the lean years of the 1980s and 1990s, when parts of the industry had set a healthy record in productivity improvement (Exhibit 1). As the demand boom gathered pa...
