analysis of lead in lead ore using aas Solutions Just Right For You

The ability to fire assay a substance relies on a number of facts First of all the samples that contain gold and silver should be solubility in molten metallic lead and that gold and silver are insolubility in slag Fire assay also relies on the difference in specific gravity between the two liquids the molten lead and the slag This analysis of lead in lead ore using aas sterpeticavalli regression of analysis comparing bone lead to the percentage of lead extracted using ASTM D5517 found an r2 of 0 96 for the 30 day study 0 68 for the 60 day study and 0 89 for the 90 day study
