selection of raw materials ( ores from different mines), the melting point and chemistry of the slag can still be controlled to some extent to about °C and 3050% MnO.
Salinity, iron, manganese and many cation and anion concentrations increase, whereas oxygen is significantly depleted. Mobilisation of barium and strontium from the rock mass indicates fast chemical dissolution reactions between the subsurface flow and carbonate minerals. Other metals mobilised include zinc, cobalt and nickel.
