Buffer system for use in rock salt or hard salt deposit locations with long-term stability against acidic influences based on magnesium deposit has brucite, dolomitic hydrated lime, rock salt, saline solution in defined proportions
Buffer system for use in rock salt or hard salt deposit locations with long-term stability against acidic influences based on magnesium deposit has brucite, dolomitic hydrated lime, rock salt, saline solution in defined proportions
The system has 30 to 70, preferably 36 to 60, parts brucite by weight, 2 to 8, preferably 3 to 6, parts dolomitic hydrated lime by weight, 0 to 30, preferably 1 to 25, parts rock salt by weight and 20 to 50, preferably 30 to 40 parts of a saline solution by weight, with magnesium chloride in a concentration of 100 to 300 g/l and magnesium sulfate in a concentration of 0 to 20 g/l, whereby the rock salt component can be fully or partly replaced by brucite in equal quantities.
