SYNTHETIC DOLOMITE
synthetic dolomite has been formed by precipitation from a solution of Mgclu, caclz, and urea subjected to elevated temperatures and COg pressures. The CO: pressure is not critical above two or three atmospheres but the temperature must be in the range 200" C.-
Dolomite application for the removal of nutrients from ...
As the aim of this study is to determine the feasibility of using dolomite as an H + neutralizer and in phosphate capture during the electrolysis of synthetic swine wastewater, a novel combination process was designed for the simultaneously removing the TAN and phosphate. First, the effect of the addition of dolomite on nutrient removal through the electrolytic process was examined.
Polymer Nanoparticle Synthesis | Dolomite Microfluidics
Synthetic and natural polymer particles represent a mobile substrate that can be biochemically tailored – this is known as surface functionalization. The process involves covalent immobilization of proteins, peptides, and nucleic acids to stone end groups exposed on the surface of the solid particles.
GMT - Synthetic Diopside: A Substitute For Dolomite
The synthetic diopside uses two primary raw materials, sand and lime, and a special binder and catalyst package to economically synthesize a chemically consistent, high purity diopside. Lime is the product of decarboxylation of dolomite (CaMg(CO 3 ) 2 or calcite (CaCO 3 ).
MgO Dolomite Flotation - 911metallurgist.com
A selective dolomite flotation process has recently been developed at the University of Florida whereby a two stage conditioning technique is utilized to remove MgO impurities. Previous investigations have mainly involved studies on synthetic apatite/dolomite mixtures in a microflotation (Hallimond) cell.
