specific gravity test for gold nuggets

9 行 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

SPECIFIC GRAVITY FORMULA Nugget Shooter

Now multiply Air weight by .5592 to give 4.9 grams of gold If you have an ironstone specimen, replace 2.65 (which is just the 'density' of quartz),with the density of your ironstone. To do this, find some ironstone (free of gold or quartz) around where you find the specimen, and find out its density following steps (1) to (3) above and plug it in.
