About 15 percent of the gold produced in the United States has come from mining other metallic ores. Where base metals such as copper, lead, and zinc–are deposited, either in veins or as scattered mineral grains, minor amounts of gold are commonly deposited with them.
Through the application of the Rietveld method, Xray diffraction analysis has developed into a fully quantitative method for phase analysis of metallurgical products. The Rietveld method itself has progressed from an unstable method that required constant operator intervention to a stable and robust method suited even for routine process control.
In addition to modern methods of analysis can also be used a simple method by using a chemical solution to see the presence of metallic mineral deposits of gold from rock samples that were analyzed. This method is very simple and easy to do and .
