Dolomitization Wikipedia

Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite.It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkha area. Dolomitization involves substantial amount of recrystallization. This process is described by the

Dolomite Mineral and Healing Properties

Dolomite is a common sedimentary rock-forming mineral that can be found in massive beds known as dolomites. These beds may be several hundred feet thick. Dolomite also forms as sediments in ore veins such as limestone. Limestone where dolomite is present in more than a small amount are called dolomitic limestone.

Magnesium: extraction-Metalpedia

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.

How do I make PLGA microparticles? Dolomite Microfluidics

Dolomite’s unique 3D pore junction is the core feature of these microfluidic chips. The 3D pore is an opening in the channel: droplets emerging from the pore do not contact any part of the glass channel walls. This helps to give chips a long life and allows easy cleaning when working with sticky polymers such as PLGA. Evaporation process
