Kieserite induced very little changes in soil pH and all modifications in the composition of exchange sites were achieved after the passage of the sulfate peak. In the A substrate, the increase of Mg loading resulted from an exchange process with Ca, whereas it was achieved at the expense of exchangeable Al in the B substrate.

The fact that this country retains a lot of dolomite deposits and such a material can be processed into synthetic kieserite by sulphatization process seems promising for fertilizer industry in Indonesia. Varying the sulfuric acid concentration between 2 and 5 N and its volume from29.50 to 94.80 ml produces the MgO in MgSO4 filtrate below the ...

The main data defin-ing the kiln capacity are: the raw material (dolomite) consumption is 6.7 tones per hour and the sinter dolomite production is 3 tones per hour. The kiln operates in average about 7300 h per year. Heavy oil consumption is about 375-400 L per hours or 125-133 L per ton of sin-tered dolomite.

Kieserite is primarily obtained from deep underground deposits of minerals. The ore is brought to the surface where the magnesium salts are separated from potassium and sodium salts using a unique, dry electrostatic (ESTA) process. Kieserite forms naturally in marine evaporate deposits where seawater has been concentrated and exposed to ...
