Reduction Roasting of Tin Bearing Iron Concentrates Using

A novel method of reduction roasting of tin-bearing iron concentrates using pyrite (FeS 2) is proposed, in which hematite in tin-bearing iron concentrates is reduced to magnetite (Fe 3 O 4) and cassiterite (SnO 2) is transformed to volatile tin sulphide (SnS).In a certain range, tin removal and iron reduction rates both increase with roasting temperature, pyrite amounts and residence time.

Pyrite roasting an alternative to J sulphur burning

Introduction. Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available. In addition to these two applications, Figure 1 shows a wider variety of sources for the production of sulphuric acid, as there are also …
