    2020-11-10 · Abstract—Gold and silver are capable of forming stable natural compounds with different elements. For gold 36 minerals are known: 10 in the class “Native metals, intermetallic compounds” and 26 in the class “Sulfides (selenides, tellurides, arsenides, antimonides, bismuthides).” For silver, 194 minerals are registered in the MMA, presented in 8 classes.

The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using currentHow to Assay Gold & Silver Ore,2017-5-11 · Classification of Ores. In fluxing ore for gold and silver, first determine the nature of the sample submitted for assay. Three different classifications may be made in the preliminary examination of ores; first, pure quartz (very glassy or vitreous); second, no quartz (plastic and free from grit); third, a mixture of these two extremes which may be assumed to be the average as

The ore was crushed fine in a ball mill, then run with cyanide and bromine. Extraction was well over 99%, even without eliminating the sulfides.Processing Gold from Sulfide Ores Assaying, Microscopy,1 天前 · They said it had a lot of silver and copper, but no gold. A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold.

According to the Environmental Protection Agency, gold is commonly mixed (alloyed) with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. The ore does not commonly have visible shiny gold on the surface.
