INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure antimony is refined.[]Web

Description of the gold-antimony flotation process. In order to separate gold and antimony from the raw ore, a preferential-bulk flotation technique is employed during the gold-antimony flotation process. It contains two parts (Li and Gui, 2018): (1) separating gold in a weak-alkaline environment; (2) recovering antimony under a weak-acid ...Web
