Assaying Lead Determination Method Pb

2020-12-9 · The chief ore of lead is galena, a sulphide of lead, common in most mining districts, and frequently associated with blende and copper-pyrites. It always carries more or less silver; so that in the assay of the ore a silver determination is always necessary. Carbonate (cerussite), sulphate (anglesite), and phosphate (pyromorphite) of lead also occur as ores, but in much smaller quantities

8.E: Gravimetric Methods (Exercises) Chemistry

The solution is heated to boiling and 1:1 NH 3 is added dropwise till the indicator turns yellow, precipitating Al(OH) 3. The precipitate is held at the solution’s boiling point for several minutes before filtering and rinsing with a hot solution of 2% w/v NH 4 NO 3. The precipitate is then ignited at 1000–1100 o C, forming Al 2 O 3.
