generate a database of these properties using a suite of in house metrology methods This methodology will afford a uniform and consistent database for the needed properties necessary to model gypsum board assembly performance under a fire load To this end, the Hot Disk Thermal Constants Analyzer® (TPS 2500)@ was used to determine the room temperature thermal conductivity and specific heat
The extraction process of lithium, socalled gypsum method consisted of sintering the concentrate with CaSO 4 and Ca(OH) 2, subsequent leaching of the sinters obtained in H 2O, solution purifiion and precipitation of Li 2 CO 3 It was observed that almost 96% lithium extraction was achieved if sinters prepared at 950°C Standard Test Methods for Chemical Analysis of Gypsum and 11 These
The present invention relates to a method of purifying flue gas desulfurization (FGD) gypsum The method is characterized by comprising the steps of a) providing an aqueous slurry containing said FGD gypsum, b) passing said aqueous slurry to a magnetic separator, and c) contacting the FGD gypsum to be purified with a solution containing an acid and having pH below 5 in an acid washing step
The method is particularly suited to the extraction of alkali and alkaline earths, but has also been applied to the assessment of the percentage extraction of transition metal ions Thus, a liquid–liquid extraction method is used to determine the percentages of extraction for a series of metal ions and frequently tabulated or plotted against ionic radii to illustrate the ion preference of

For the extraction of these compounds, modern methods (Supercritical Fluid Extraction (SFE), Subcritical Water Extraction (SWE), UltrasoundAssisted Extraction (UAE), and MicrowaveAssisted Extraction (MAE)) have been used due to their advantages over the conventional methods The process parameters of each method must be optimized for obtaining the extracts with the targeted bioactive
Gypsum has a density of 2317 Mg m3, so methods using Stokes' Law which assumes an average particle density of 265 Mg m3 overestimate the clay and silt fractions of soils if not corrected 3 In the pipette method, during drying of each particlesize fraction, gypsum loses its water of crystallization and consequently, the fractions of soils containing most gypsum are underestimated unless
