OUTOTEC ROASTING SOLUTIONS

Our partial roasting process is used for removing impurities from feed material. In this process the sulfur is only partially roasted, with the quantity depending on the concentrate analysis and the desired calcine grade. In some cases, partial roasting is used to remove almost all unwanted elements – such as arsenic and antimony –

Development of Secondary Antimony Oxides from ...

Antimony trioxide volatilizes easily at higher temperatures. This property is used in different industrial applications such as roasting of sulfidic antimony ores where the anti-mony is separated as trioxide via the offgas due to its high vapor pressure. Production of high-purity antimony triox-ide from high-grade antimony metal is considered state of

Oxidizing Roast; Stibnite the Antimony Mineral

The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation. In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to ...
