The act or process of testing, esp. of analyzing or examining metals and ores, to determine the proportion of pure metal.
The most promising hand samples and core are invariably submitted to an accredited laboratory for analysts. This process, in which the precise chemical composition of the rock and it's mineralization cataloged, is called assaying.
process that determines the concentration of pure metal within a sample of ore
Testing precious metals to determine the standard of purity.
The process of determining the fineness or the constituents of a metal or alloy.
The process of determining the proportion of precious metal contained in an alloy. Most jewellery is assayed at an official Assay Office and given a hallmark that indicate the type and fineness of the precious metal.
To test the composition of (an ore, alloy, or other metallic compound) by chemical means, so as to determine the amount of a particular metal contained in it; to determine the degree of purity of one of the precious metals. See:Metallurgical Processes*.
