the main mineral component of dolomitic limestone

British Geological Survey2.88 Мб. Dolomitic limes are generally less reactive than equivalent high-calcium limes because of the tendency of the MgO component to 'dead-burn'.Pure dolomitic limestone will give a greater loss than limestone since the mineral dolomite loses 48%of its weight as C02.

Dolomitic Limestone - an overview | ScienceDirect Topics

In many cases the pH of biochars is very high (Table 8.22).However, this may allow replacement of some or all of the dolomitic limestone that is normally used to neutralize peat. Zaccheo et al. (2014) investigated the potential of a biochar prepared from pinewood with a pH of 10.2 to neutralize peat with a pH of 4.2. Proportions of 30% and 40% were most effective in adjusting the pH to a ...

What is Dolomitic Limestone? (with pictures)

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone ...
