Phanerozoic variation in dolomite abundance linked to oceanic anoxia
Geology, 2021The abundance of dolomitic strata in the geological record contrasts with the general rarity of locations where dolomite forms today, a discrepancy that has long posed a problem for their interpretation.

Green Chemistry
Apatite and dolomite presented challenges in their separation due to their similar surface chemistry. To achieve flotation separation of apatite and dolomite, depressants were required, but the conventional depressants had...

Chapter 7 Dolomites and Dolomitization
1979Publisher Summary This chapter discusses dolomites and dolomitization. There are numerous kinds of dolomite. According to numerous investigators, primary precipitation of dolomite crystals, particularly in marine environments, probably represented in Holocene carbonate sediments, is of little significance when considering the great bulk of ancient ...

Air-gasification has emerged as preferred means of converting biomass to valuable synthesis gas (syngas). In present work, the gasification characteristics of pine sawdust were studied in a small-scale fluidized bed using calcined dolomite as in-bed ...

II.—Dolomitization and the Leicestershire Dolomites
Geological Magazine, 1918In the district north of Ashby-de-la-Zoueh dolomitized Carboniferous Limestone crops out where the Leicestershire border adjoins that of South Derbyshire. The dolomites, which attain a thickness of nearly 900 feet in this area, have hitherto received very little attention.

Effect of Tween 80 on flotation separation of magnesite and dolomite using NaOL as the collector
, 2020Dolomite is difficult to be separated from magnesite by sodium oleate (NaOL) because of their same crystal structure, similar chemical composition, and high solubility.
