Problem When Roasting Iron From Antimony Ore

Roasting an overview ScienceDirect Topics

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. Oxidation roasting equipment includes a rotary kiln, a multichamber baking furnace, and fluidized baking furnace (see

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.

Extraction of Antimony

The reduction in pots is carried out in three stages: (1) A mixture of liquated ore, wrought iron and common salt is fused together and a crude product obtained containing about 90 per cent, antimony and 7 to 8 per cent, iron; (2) this is again remelted with more liquated ore and common salt, the bulk of the iron being thereby removed; (3) finally this second product is remelted with a special

Roasting Of Iron Ore For Ugradation. In this study, a combination of alkali roasting and hydrothermal treatment is used as a method of gangue Si, Al, and P removal from iron ores as a means to upgrade low-grade iron ore limonite into a high-grade iron ore with low gangue content, low porosity, and high Fe and Fe2O3 content to enhance the sustainable development of iron and steel industries.

2PbS + 3O2 → 2PbO + 2SO2 (1) 2ZnS + 3O2 → 2ZnO + 2SO2 (2) 2FeS2 + 5.5O2 → Fe2O3 + 4SO2 (3) 4FeAsS(s) + 3O2(g) → 4FeS (s) + 2As2O3(g) (4) Ores containing antimony may present special problems during oxidative roasting. Stibnite readily decomposes to form antimony trioxide and sulfur dioxide, as follows: 2Sb2S3 + 9O2 → 2Sb2O3 + 6SO2 (5) The antimony trioxide can cause

Smelting and Roasting Ores to recover gold, silver and

The problems with processing sulfide ores by the normal methods and the fact that most of those problems can be removed by first roasting the ore, led to the development of a variety of ore roasting systems that were installed in the mills of that day. Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur

OUTOTEC ROASTING SOLUTIONS

Iron sulfides are transformed into iron oxides, with the production of sulfuric acid being an important output of this process in terms of ensuring its economic viability. In a typical pyrite roasting plant gas temperatures can be over 800°C at the inlet of the waste-heat boiler, which is suitable for high-pressure steam production. Gold-bearing feed When processing concentrate that contains
