Abstract

The objectives of this paper are to perform research on the principles used to identify the purity of gold, suggest and build a simulation model as an alternative way to determine the purity of gold and able to compare the results obtained. Gold purity determination is important because the price of gold depends on its purity. The purer the gold is, the more expensive the price will be. There are two common methods in determining the purity of the gold bar, which are the destructive and non-destructive methods. The destructive method will destroy the gold sample such as the fire assay method. The non-destructive method will not destroy the gold sample during the purity test. Some of the non-destructive technique used is density, XRF and Ultrasonic are discussed in the review.
