stibnite grinding media

Kohl (cosmetics) - Wikipedia

Kohl (Arabic: كُحْل, romanized: kuḥl), Kajal, Kajol, or Tiro is an ancient eye cosmetic, traditionally made by grinding stibnite (Sb2S3) for use similar to that of charcoal in mascara. It is widely used in the Middle East, Caucasus and North Africa, South Asia, West Africa, and the Horn of Africa as eyeliner to contour and/or darken the eyelids and as mascara for the eyelashes. The content of kohl and v

SELECTIVE EXTRACTION OF MERCURY AND ANTIMONY

Grinding to minus-100-mesh liberated the cinna-bar and most of the stibnite. Gravity methods of concentration yielded only partial separation of cinnabar and stibnite. A sample of the ore was ground to approximately 65-mesh with sodium cyanide to depress pyrite; a cinnabar-stibnite bulk concentrate was floated with a higher xan-thate collector.

US4081364A - Froth flotation method for stibnite - Google Patents

Disclosed is a process for concentrating stibnite (antimony sulfide) and separating it from iron sulfide minerals such as pyrite by froth flotation using untreated recirculated water or mine water which is acidic and may be heavily loaded with metal salts. The process features the use of a water-soluble zinc-cyanide complex salt to depress iron sulfide minerals.
