Researcher investigates carbonate mineral chemical ...

2021-2-13  Current modeling methods assume both dolomite and calcite have an ideal chemical composition that does not vary spatially within the carbonate reservoir. Thus, reservoir rock is thought to react at the same rate everywhere when acids are injected to dissolve the rock and form the channels or wormholes for oil and other hydrocarbons to travel ...

About Midatlantic Minerals inc.

In the late 90's, we vertically integrated and built a processing plant in the Port of Quebec to beneficiate dolomite and added a new mineral to our product line; high calcium limestone. This added a new expertise to our group. Low iron dolomite was also introduced in this same time period to the product line.

Dolomite - University of California, Berkeley

1996-11-15  Dolomite is, after calcite, the second most important and abundant of the carbonate minerals. Chemically and structurally, it may be regarded as calcite with half the calcium ions replaced by magnesium. Iron or manganese may substitute for magnesium in dolomite, forming isostructural series with ankerite and kutnohorite.
