Understanding these fluidmineral interactions requires thermodynamic and kinetic data derived from experiments. The GEODE programme is conducting experiments to obtain such data spanning all five of its projects. Europe is well placed for
Extraction of Resources. To gain access to the mineral deposit within an area it is often necessary to mine through or remove waste material which is not of immediate interest to the miner. The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the
