Gold is one of the heaviest minerals. When pure, it has a specific gravity of 19.3. Due to its weight, it can be panned because the Gold sinks to the bottom. In addition, it can be easily separated from other substances due to the weight differences. Gold is also the most malleable and ductile substance known.

· High-grade gold ore contains high concentrations of gold, typically ranging from 5 to 20 grams of gold per ton (g/t), or 0.15 to 0.6 ounces per ton (opt). High-grade ore is considered highly valuable and economically attractive for mining and processing. It requires less processing and extraction methods to recover significant amounts of gold.

Updated April 25, 2017. By Christina Hadley. To the untrained eye, gold ore may look like rock with copper tones flowing within it. However, professional prospectors know how to recognize gold ore within a multitude of minerals. Recognizing the look and the location of gold ore is easier if you know how to find lode and placer deposits.

· The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold
