Stibnite froth flotation: A critical review ScienceDirect

2021-3-15  For the case of stibnite, they affirmed that the charges are much greater on lead atoms than on copper atoms, which might explain a more widespread use of a lead salt over a copper salt as stibnite activator; this is because the total energy for copper-activated stibnite is lower than that of lead-activated stibnite.

2015-12-27  antimony minerals, stibnite, tetrahedrite (Cu3SbS3) and lead ores are the major sources for Sb as far as commercial extraction is concerned. Dissolution of the stibnite in alkaline solution involves the formation of various soluble species, such as antimonites, thioantimonites, oxothioantimonites, sulphites, thiosulphates, etc.

Stibnite an overview ScienceDirect Topics

Antimony (Sb, stibium) is a semimetallic element that belongs to the vanadium family (Group VA) of the periodic table and shares certain chemical and physical properties with lead, arsenic, and bismuth [ 1]. In nature, antimony is associated with sulfur as stibnite and occurs in ores with arsenic.
