[3] Because the Bessel process was used on graphite not gold, silver, copper, lead, zinc, etc, their work has been ignored by most historians of the technology. Inventor Hezekiah Bradford of Philadelphia invented a "method of saving floating material in ore-separation” and received US patent No. 345951 on July 20, 1886. He had received his first patent in 1834, primarily invented machinery
Jul 01, 2020 The selective flotation separation of chalcopyrite and pyrite can be achieved in neutral or alkaline media with a low concentration of it. A2 As the high-efficiency collecting and foaming agent for copper and gold, A2 has a high selection rate and good separation effect of copper-gold and sulfur. J622 The collector of Cu-Ni ores. BJ-306
After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony. Approximately 25 percent of the silver produced comes from ores actually mined for their silver value; the other 75 percent comes from ores that have as their major metal value either lead

Oct 19, 2007 In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to selectively separate tennantite
