.SUMMARY
The mining-metallurgy plant at ~biec near Stara" chowice produces a concentrate of iron, so . called "zelgruda", of ferruginous sands occurring in its vicinity. After the concentration processes, a
:
raw
material
for metallurgy with c. 8'S'/.-FeIO, corttent,as well as Il'emarkable amounts of residuary (pOst--flotational) sands ate obtained. The iron' oxide .. ' content . in these residuary sands is yet quite high; This, as well
as
the resul1ing rusty colour make these' sands difficult to sell. However, the sands are cpa-racterized by a high temperatureot
·agglomeration, so it would be possible to adapt them to ·the require-' ments of founding, . after elaborating suitable method; of separation. The authors discuss the process of treating the sands according to' the. fo~nderUig re-' quirements as an example of, selecthlg .. a· suitable separation method..Tabela n
