Roasting an overview ScienceDirect Topics

K.G. Thomas, A.P. Cole, in Gold Ore Processing (Second Edition), 2016 Abstract. Roasting of ores and concentrates can be defined as the heating of a material to cause reaction and the expelling of volatile matter without causing fusion. Oxidative roasting is used extensively to pretreat base and precious metal–bearing materials and to oxidize iron sulfides to generate sulfur dioxide for

EiC July 2008 Feature Antimony revisited. Antimony lives in the neighbourhood of arsenic and shares similar traits not found alone'.2 Indeed, antimony is usually found as the sulfide ore, stibnite, Sb2S3, 250 years earlier.4 The process involved roasting stibnite to form the oxide, in which stibnite was reduced directly to metallic antimony by reaction with iron.

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

The invention relates to a method for removing antimony from refractory gold ore and preparing cubic crystal sodium pyroantimonate. The method comprises steps of leaching the antimony containing refractory gold ore in a mixed system of Na2S and NaOH, so as to dissolve the antimony into leaching agent in the form of sulfo-antimonous acid sodium, adding a precipitant into the antimony containing
