Specific gravity test for gold - Goldbay

Aug 19, 2014  The simplest way to test specific gravity is weigh the quartz gold specimen in “air” and multiply the weight by 1.9. Then weigh the quartz gold specimen fully submerged in “distilled water” and multiply that weight by 3.1. Minus the wet figure from the dry figure and you will get a fairly accurate specific gravity for that specimen!!

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 Test : GoldNuggetSales

A Specific Gravity Test is used to calculate the amount of gold contained in a gold nugget that contains a mixture of gold and quartz. You need two pieces of information to do the calculation. You need the weight of the specimen in air and you need the weight of the specimen when it is suspended in water.

Specific Gravity of Gold Calculation Learn how to easily ...

Step 7. Match your calculation with the specific gravity to find out the metal purity in the chart below. Once you determine the specific gravity, it is important to note that tungsten gold bars are almost the same specific gravity as 24k gold bars. Tungsten’s specific gravity is 19.25 and 24k gold is 19.32.

Desert Gold Diggers - Specific Gravity Test

Feb 09, 2008  The default values below are for gold, using an average specific gravity of 18.6, and quartz, using a specific gravity of 2.65. These values assume a specimen of gold in a matrix such as quartz. However for a gold nugget, containing another mineral such as silver, use the specific gravity of pure gold, 19.3, and pure silver, 10.5.

Specific Gravity - The Gemology Project

Dec 13, 2016  Consider two balls of equal weight but of different specific gravity, for instance a 10 gram gold ball and a 10 gram silver ball. The gold ball has a sg of 19.3, while silver has a sg of 10.5. Because gold has a sg that is almost twice as much as silver, you can imagine that the 10 gram gold ball will be smaller than the 10 gram silver ball.
