A system is provided for improving dust collection efficiency at a sinter band device. The system includes a sinter band with material handling stations and auxiliary equipment operative to sinter a metal or metal ore, a primary electrostatic precipitator operative to remove primary dust from a primary gas stream that has passed through a bed of sintering material on the sinter band, and a secondary dust collection device operative to remove secondary dust from a secondary gas stream emanating from one or more suction points at the material handling stations and the sinter band. The secondary dust has a lower electrical resistivity than the primary dust. A dust transportation line is provided operative to transport secondary dust to the primary gas stream downstream of the sinter band, and injecting it at a position upstream of the primary electrostatic precipitator and/or directly into the precipitator itself.
