The entire antimony flotation procedure and its online capture of the mixed minerals' Raman spectra in the layer from the cleaner cell are illustrated in Fig. 1.As shown in Fig. 1, the unprocessed antimony ore is crushed into micron-sized particles, mixed with water to create a slurry, and then supplied into a mixing tank.At the same …
Antimony Ore/Concentrate. The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals. Eighty percent of the world's antimony is produced from two types of deposits — carbonate replacement deposits and gold-antimony epithermal deposits. There are two types of …
