Dolomite - an overview | ScienceDirect Topics

Dolomite was the first fertilizer used to prevent hypomagnesemia (Cunningham, 1936).When applied at rates between 100 and 540 kg Mg/ha the Mg concentration of temperate forage is increased by 0.2–1.2 g/kg DM (Table 9.13).These increases in Mg concentration in the forage were associated with a rise in the level of exchangeable Mg in the soil (Jones, 1963b;

Major Mines & Projects | Garpenberg Mine

With the cut and fill method, mining is carried out in slices along the steeply dipping, narrow ore body. The bottom slice is mined first. The excavated area is then backfilled, so mining can continue with the slice above. The rill method used in Garpenberg is in fact similar to longitudinal stopping, but the stopes are split in 20 m long slices.
