Froth flotation plays a key role in the recovery of stibnite from primary and secondary sources. A critical literature review on stibnite flotation had not been undertaken for …
in the Lake George (New Brunswick, Canada) stibnite-quartz deposit, but it is present in a minor vein set ( Seal and others, 1988) and has not been extracted during mining and milling of the ore. Relative to simple, disseminated, and gold-antimony deposits, stibnite-quartz deposits lack significant copper, lead, zinc, and nickel sulfide and
One of the major topics reviewed is stibnite flotation reagents; while the overall practice has been mostly conservative, relying on the use of xanthate collectors and lead nitrate as an activator ...
Process flow sheet for gold and antimony recovery from . Process flow sheet for gold and antimony recovery from stibnite In particular in the case of stibnite Sb 2 S 3 the antimony Sb forms stable compounds with sodium cyanide NaCN during the cyanidation process; as a consequence cyanide consumption increases Pretreatment is usually an ...
Tailings from mineral processing plants are generated in various categories, depending on the type of ore (mineralogy) and the mineral processing technology (gravity separation, flotation, leaching etc.) (Marsden and House, 2006, Araujo et al., 2022).An example of this material is the tailings from the stibnite flotation process (Güven et al., 2012, Radková et …
Jamesonite is a typical sulfosalt mineral as well. It is commonly associated with other sulfides such as pyrite (FeS 2), stibnite (Sb 2 S 3), galena (PbS), sphalerite (ZnS) and others, and detected as the needle crystals in a hydrothermal vein in nature (Anthony et al., 1990).The mineral occurs as lead-gray hair-like crystals up to one-centimeter-long which are …
