Gold A test known as Dartons is believed to be a valuable means of detecting minute quantities of gold in rocks, ore tailings, etc. Small parts are chipped from all the sides of a mass of rock, amounting in all to about ounce. This is powdered in a steel mortar and well mixed. About half is placed in a capacious test tube, and then the tube is partly filled with a solution made by ... With ores of higher gold content (i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.

Solutions to this problem typically propose the use of larger sample sizes, typically 30 g or greater. 3 Furthermore, when using acid digestions, in the absence of hydrofluoric acid, low recoveries have been associated with the encapsulation of gold in the siliceous rock. 1,2,4,5 Here, it is presumed that gold is secreted within a refractory matrix, making it inaccessible to solvent solutions. require here that the true gold content be no more than approximately 50 percent larger or smaller than the gold content obtained by chemical analysis of a sample. Jiowever, because of random variation in gold content from sample to sample, it is impossible to be completely certain that the true gold content will be within a given range of values.
