Gold Gravity Concentration - Mineral Processing & Metallurgy

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the "concentrates," in which the precious metal is ...

specific gravity test for gold nuggets

9 · In this example of the specific gravity test, we use gold mixed with quartz. Nugget weighed in air weighs 96 grams. Nugget suspended in water weighs 74.5 grams 96 - 74.5 = 23.5 96 divided by 23.5 = 4.17 (the specific gravity of the specimen) 4.17 - 2.63 (the average specific gravity of quartz) = 1.54
