Sinter Plant Operation
Oxide Use in Sintering. The original function of the sintering process of the I.S.P. is both to eliminate sulfur and to make hard sinter from zinc and lead sulfide concentrates. But the imbalance of the sulfuric acid demand/supply and various policies on resource recycling have required us to treat a great deal of secondary non-sulfidic materials.

Sintering
Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.

This reduces off-gas volumes by about 40–50% without affecting the sintering process. In an emission optimized sintering plant, the whole sintering gases are collected and then forced to recirculate on the sintering surface to contribute to the material heating (Fig. 3.18). In this way <50% of the waste gas is emitted in the atmosphere.

Composition of Lead Sinter
In some of the earlier roasting systems lead was produced by the roast reaction process and separated from the charge. The gray slag material from the roast reaction process and high-silica ores served as feed for the lead blast furnace. Lead sintering, as used in the lead industry today, is a method for preparing feed for the lead blast furnace.
