Measuring the Amount of Metal Carbonate in an Ore
1 Measure out an amount of metal carbonate ore 2 Place the copper carbonate ore into a 250 cm3 beaker 3 Measure out exactly 25 cm3 of hydrochloric acid 4 Pour the hydrochloric acid into the beaker of copper carbonate ore, start the stop clock then swirl once 5 When the fizzing appears to slow down swirl the beaker once more to make sure 11 This test method covers the determination of carbonate content of soils and soft rock which can be readily broken down by mechanical effort It is a gasometric method that uses a simple portable apparatus Results should be clearly stated as the calcite equivalent in percent because different carbonate species cover a wide range of percent Standard Test Method for Determination of To measure these elements, the sample must be digested and put into a water solution There are several methods to put the elements into solution, but the most common is to dissolve them in a heated solution of aqua regia acid (aqua regia is a combination of Hydrochloric and Nitric acids)Assaying Ores to determine gold content Nevada A sample of strontium ore is known to contain strontium oxide, strontium carbonate and some inert impurities To determine the mass of strontium carbonate present, a student weighed a sample of the solid ore and then heated it in a crucible for 5 minutes The sample chemhumecoukMgO, CaO, Al2O3 etc) If the sample is a sulphide ore, you can get the analytical result in the form of sulphide percentage of the relevant elements It takes only about 3 minutes to get a How can I determine the composition (as compounds)
calculating percentage of caco3 in a limestone sample
"Limestone is an ore of calcium that contains a high proportion of calcium carbonate (CaCO3) Calcium carbonate reacts with hydrochloric acid (HCl) according to the equation: CaCO3 + 2HCl > CaCl2 + CO2 +H2O 122 General Guidance for Sample Preparation Some general considerations during sample preparation are to minimize sample losses and to prevent contamination Possible mechanisms for sample loss during preparation steps are discussed in Section 1221, and the contamination of samples from sources in the laboratory is discussed in Section 122212 LABORATORY SAMPLE PREPARATION For our 0812g of sample, 100ml of 04M Sodium Carbonate are required while for 12g sample 100ml of 08M Sodium Carbonate are required To prepare 04m Sodium Carbonate anhydrous sodium carbonate is used and to make sure that there is no water present in the hygroscopic compound, some of this compond is preheated to evaporate any water Analytical analysis of Aluminium in a sample [MarZ 5 When barium carbonate is added to dilute hydrochloric acid, carbon dioxide gas is formed A student carried out an experiment to measure the volume of gas formed as a reaction proceeds The student added a small mass of powdered barium carbonate to an excess of 01 mol / dm3 hydrochloric acid A graph of the results was drawn The graph is Cambridge International Examinations Cambridge
