Feb 24, 1998· The present invention relates to a method of floating calcium carbonate ore containing silicates as impurities. According to the invention, flotation is performed in the presence of a quaternary ammonium compound and an alkylene oxide adduct of an amine compound, the silicate being concentrated in the float.
Standard Test Methods for Calcium and Magnesium In Water1 This standard is issued under the fixed designation D 511; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
5.1 This test method is used to determine the presence and quantity of carbonate in a soil specimen in terms of the calcite equivalent. The method is generally intended for use as an index of approximate carbonate content to assist with characterizing marine soils.
The aim of this study was to produce precipitated calcium carbonate (PCC) with different morphologies from dolomite ore (CaMg(CO 3) 2) by means of leaching and carbonation method. The optimal experimental conditions determined in our previous study for the leaching process was conducted. During the leaching process, CO 2
The invention relates to a method of floating calcium carbonate ore containing silicates as impurities. Floatation is performed in the presence of a quaternary ammonium compound and an alkylene oxide adduct of an amine compound. The silicate being concentrated in the float.
Calcium oxide is a basic oxide and reacts with acidic oxides such as silicon dioxide present in the rock. Calcium oxide reacts with silicon dioxide to give calcium silicate. The calcium silicate melts and runs down through the furnace to form a layer on top of the molten iron. It .
calcium carbonate ore which would otherwise be responsible for colour imperfections in the finished product [8]. The most important criteria in evaluating the performance of calcium carbonate collector during floatation is the dosage level required and the yield of calcium .

Cleaning methods for stainless steel. ... Suitable cream cleansers are available with soft calcium carbonate additions, e.g. 'Jif', or with the addition of citric acid, ... Rust marks or staining on stainless steels is unlikely to be the result of corrosion to the stainless steel itself (similar marks may also be found on porcelain and plastic ...
hardness of water is defined in terms of its content of calcium and magnesium ions. Since an analysis does not distinguish between Ca2+ and Mg2+, and since most hardness is caused by carbonate deposits in the earth, hardness is usually reported as total parts per million calcium carbonate by weight.
The basic LOI method Determination of weight percent organic matter and carbonate content in sediments by means of LOI is based on sequential heating of the samples in a muffle furnace (see Dean, 1974; Bengtsson & Enell, 1986 for more details on the method, but note that in the equations for calculation of LOI in the latter publication the
The precipitation of calcium carbonate is of considerable importance in a wide variety of scale forming situations since carbonate concentrations in the environment are usually quite appreciable. As a first-formed solid phase, calcium carbonate may induce the growth of other scale minerals on its surface.
Table 2. Recovery data for lithium, sodium, and calcium spiked in lithium carbonate samples containing 50 mg/L lithium. Sample Accuracy and Precision Method accuracy was validated by spiked recoveries of lithium, sodium, and calcium in lithium carbonate samples .
