[QUOTE="BHM14, post: 483078, member: 14400"] A bit late at night to do the maths but I found this. I guess youve used the same formula. The Specific Gravity Test is used to calculate the gold content of gold nuggets that contain a mixture of gold and other materials. 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 1.54 x 23.5 = 36.19. 36.19 divided by the constant 25.97 = 1.39 ounces of contained gold 1.39 ounces x 31.103 = 43.23 Grams of contained gold. The specific gravity for quartz is 2.60 - 2.65. [/QUOTE]
