احصل على السعرGenerally, silver comes to market as a byproduct of the industrial mining of other metals, such as copper, zinc and gold. In 2024, only 30 per cent of silver came from actual silver mines. It is no high honour to be grouped into 'one of the world's most destructive industries', as the industrial mining industry is known.
احصل على السعرA double refractory gold ore contains gold particles locked in sulphides, solid solution in arsenopyrite, and preg robbing material such as carbonaceous matter, and so on. The diagnostic leach test (DLT) and preg robbing (PR) approaches are widely used to investigate the occurrence and the distribution of refractory gold. DLT serves to qualitatively evaluate the gold occurrences within the ore
