Roasting Arsenic & Antimony Ores

The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore, 1 A.T. ; red lead, 1,000 grains; sodium carbonate, 500 grains; potassium ferrocyanide, 550 grains, with a cover of salt or borax. The button is scorified, together with the matte formed, before cupellation. E. A. Smith found this method unsatisfactory and recommends the oxidation of sulphide of antimony by

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.

Antimony Ore Roasting Plant, Oman Clean TeQ Water

Antimony Ore Roasting Plant, Oman Clean TeQ Water were engaged to provide the engineering, procurement and construction of a 0.5ML/d plant in Oman. The plant uses a precipitation stage to remove antimony and arsenic, followed by Clean TeQ Water’s DESALX ® technology to remove hardness and sulfates before continuing to reverse osmosis (RO).

parameters. To avoid losses in the leaching plant, it is recommended that whole ores are treated with a gold-roasting step. Due to the low specific heat value of whole ore, it is generally necessary to add fuel to the reactor. A two-stage roasting process combines partial roasting in the first stage with dead roasting in the second stage.

Roasting an overview ScienceDirect Topics

Oxidation roasting is often used in sulfide ore smelting. It is used to remove the sulfur ore, arsenic, antimony, and other harmful impurities in ore. In oxidation roasting, the sulfide ore is first decomposed into low-valence sulfide and sulfur, and then the oxide is formed. The oxidation roasting of some sulfide ores is exothermic.

Antimony Ore Roasting Plant, Oman. Clean TeQ Water provided a 0.5MLD plant in Oman which uses DESALX® to remove hardness and sulphate before water continues to RO. The plant produces industrial quality water which is reused as process water, as part of a zero liquid brine water treatment solution.

Roasting (metallurgy) Wikipedia

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Extraction of Antimony

For roasting sulphide ores two methods are used, viz., simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide. In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed.
