Burn the dust at 650c temperture.
Sieve it & remove iron by magnet. //there should be no iron from brass!//
Take 1 kg fine dust in 5 lit. glass beaker. add 1.5 lit aqua regia (1part hno3 & 3part hcl) in it very slowly. boil the solution upto 30 min. then cool the solution amp;& then filter by using buffner funnel. add urea water & feso4 into your filtered solution till green colour reaches dark black colour. settle the solution for1hr then decant the solution in other drum. remove the brown powder in beaker. wash it very well with hcl & then wash with hot water till ph-paper does not change.then dry that powder on heater slowly & melt at 1064c in melting furnace. You could "pan" the dust to separate the less dense brass from the denser gold. If the dust particles are about the same size use threshing methods by pouring (slowly) the dust in front of a fan, the brass will be blown further than the gold.
