Bulk flotation followed by sequential flotation of gold-bearing sulfides, and depression of stibnite. This method was practised at the Bradly concentrator (USA) and consisted of the following steps: first, bulk flotation of stibnite and gold bearing sulfides at pH 6.5 using lead nitrate (Sb activator) and xanthate; second, the bulk concentrate is reground in the …

Stibnite is a sulfide minerals with chemical composition is antimony sulfide (Sb2S3). The principal ore of antimony. Lead-gray to silvery gray in color, it often develops a black, iridescent tarnish on exposure to light. It normally occurs as elongated, prismatic crystals that may be bent or twisted.

Feb 01, 2022· Stibnite can also occur as a massive form, with no overall crystal shape. Stibnite has a hardness of 2 on the Moh's Scale. It is extremely soft and brittle. As a result, stibnite is rarely used in jewelry. Color is metallic silver-gray. Sometimes, crystals are iridescent. Over time, crystals may oxidize to black.

Feb 13, 2019· The saturated vapour pressure of antimony and its sulphide and oxide at different temperatures are shown in Fig. 2.As can be seen from Fig. 2, as the temperature increases, the saturated vapour pressure of Sb 2 S 3, Sb 2 O 3 and Sb increases gradually, and the growth trend of Sb 2 S 3 is the most rapid. When the temperature is below 1201 …
