Role of Sodium Sulfide - Copper Lead Zinc Ore Flotation
2018-7-17 Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores

The effect of sodium hydrosulfide on molybdenite flotation ...
2020-3-15 HS − has a stronger affinity to copper ions than xanthate and therefore can replace xanthate on the surfaces of copper sulfides (Bhambhani et al., 2014). In addition, the addition of NaHS or Na 2 S may decrease the Eh, which prevents the oxidation of copper sulfides to form hydrophobic products such as polysulfide and elemental sulfur on the surfaces ( Taheri et al., 2014 ).

Copper Oxide Flotation - 911 Metallurgist
2013-7-25 It must be noted here that the discussion in this paper pertains to oxide copper that is typically associated with economical amounts of sulfide copper (the so called “mixed sulfide-oxide” ores) and, consequently, not treated by leaching-SX (the latter is widely practiced on low-grade ores from the “oxide

Flotation of Aladagˇ oxide lead–zinc ores - ScienceDirect
2005-2-1 The degree of oxidation in lead ores may range from slight tarnishing of the galena to complete oxidation. The most common oxide lead minerals are cerussite, anglesite, and plumbojarosite. In the case of tarnished galena, some special promoter is effective, sometimes with prior addition of sodium sulfide or sodium hydrosulfide.
