1. Introduction. In an era of high energy costs, coupled with increasing concerns regarding sustainability, improving the efficiency of water and energy use is an important goal for the mining industry .Water reticulation systems can consume up to 42% of a deep mine's total electricity usage .In addition, up to 30% of a typical deep-level mine's electricity cost can be attributed to power ...
The Yallourn Power Station is a complex of six brown coal–fuelled thermal power stations built progressively from the 1920s to the 1960s. Located in the Latrobe Valley of Victoria, Australia, the complex was situated beside the Latrobe River, with the company town of Yallourn located to .
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
