Phosphorus as phosphate and nitrogen as ammonium or nitrate are the main nutrients in wastewaters and agricultural sludges. They runoff easily to waterways and cause eutrophiion in water bodies. However, ammonium and phosphate could be precipitated simultaneously and used as recycled nutrients. In this research, dolomite calcined at 650 °C, 750 deg;C, or 950 deg;C and commercial .
Dolomite brick is a kind of refractory products that is made from calcined dolomite sand. Generally speaking, the content of the calcium oxide is more than 40%, and that of magnesium oxide is 35% above. In addition, there are materials such as aluminium oxide and iron oxide. Dolomite brick can be divided into asphalt combined unburnt brick ...
from Turkish calcined dolomite via Pidgeon process was studied under the pressure of 1 mbar. In the experiments, Turkish ferrosilicon, calcium carbide, Aluminum was used as reducing agent. Effects of FeSi (90150 % of stoichiometric requirement of silicon), "CaC 2Al" addition and time (60240 min.) were investigated on recovering of metallic magnesium from calcined dolomite (dolime) at ...

Jun 14, 2012 · A comparison of the effectiveness of totally and partially calcined dolomite additives (TCD and PCD) on the leachability of elemental constituents from three fly ashes was performed. Both additives were found effective in reducing the concentrations of several undesirable oxyanion constituents in fly ash leachates, although enhanced leaching of fly ashes was also detected as a result of ...

Technical Support Document Limestone and Dolomite Use. The five leading limestone and dolomite ...
The Stored Calcined Dolomite sample (CDS) was prepared using the same procedures as the CD sample but it was stored for three weeks. To produce the Reactivated Dolomite sample (RD), the CDS was calcined for two hours at K. Finally, the Washed Calcined Dolomite sample (WCD) was obtained by washing with methanol the CD used in a reaction cycle with a Soxhlet extractor, and then ...
MgO in the dolomite ore. The second process, which is a separation process, includes twosteps (hydration and carbonation) for the separation of alcium as Precipitated Calcium c Carbonate (PCC, 1st stage) of % purity and a magnesium recovery of % as dissolved MgCl 2. Hydration was carried out by adding 55% by weight ratio of calcined ...
What is Dolomite? Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesiumrich groundwater.. Dolomite and limestone are very similar rocks.

A process for preparing magnesiumenriched calcium magnesium acetate which includes the steps of selectively calcining dolomite in the presence of water vapor at a temperature barely high enough to cause MgCO 3 to destruct to MgO and CO 2 but low enough so as not to substantially affect CaCO 3, cooling the resultant calcined product in an ...

Apr 25, 2007 · Calcined dolomite is a superior sorbent to calcined CaCO 3 in that larger fractional conversions of CaO and improved multicycle durability are possible. With CaO obtained from CaCO 3, the firstcycle fractional recarbonation was limited to about, a value which decreased by 15 to 20% in each subsequent cycle.

Dolomitic limestone (dolomite) has normally been formed by the replacement of some of the calcium in limestone with magnesia, a process known as dolomitisation. Theoretically dolomitic lime should be a stoichiometric mixture of CaO and MgO, 58% CaO and 42% MgO. In practice, because of impurities and differing levels of dolomitisation, commercial products normally contain 30 35 % MgO .
A process is provided for the production of magnesium from magnesium oxide, generally in the form of calcined dolomite, in which magnesium vapor is produced in a heated reaction zone from solid reactants fed substantially continuously to such reaction zone.
