Jun 02, 2021 Limestone and dolomite have been formed in a variety of settings in Victoria and range in age from early Palaeozoic to Quaternary. Younger limestones tend to be friable and porous, whereas older limestones are often dolomitised and silicified, or metamorphosed and recrystallised to marble.
Limestone and dolomite are the most widely quarried rocks in Illinois, and crushed stone is the states most important rock product. Millions of tons of stone are crushed annually for use as construction aggregates, road surfacing material, agricultural limestone, and lime. ...

Apr 01, 2006 Limestone and dolomite are relatively insoluble at pH values greater than 7, and therefore, pre-oxidation of ferrous ions to ferric ions is necessary for effective removal of iron from acid mine water (Maree and du Plessis, 1994).

Some Issues in Limestone Mining. Limestone is most often mined from a quarry. However, underground limestone . mines are found at places in the central and eastern United States, especially in and near cities. Underground mining of lime - stone has some advantages over surface quarrying and will probably increase in the future.
The largest dolomite mining operation in Australia is at Ardrossan on northern Yorke Peninsula, where Arrium Mining Ltd operates a quarry, crushing plant and ship-loading facility. Full production was commenced by BHP in 1950, with production in 2013 in the order of 400,000 tonne. The dolomite is fine grained, dense, and yellow to brown in colour.
In the South African limestone and dolomite industry, there are currently 24 producers and 43 quarries. Eleven limestone producers supply 80% of the South African market. Dolomite and limestone are used commercially in unprocessed, ground, air-separated, precipitated and calcined forms. Cementitious products are derived from a blend of limestone,
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earths sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
