The following basins in Pbland possess lead-zinc ores: the Bytom (Heathen; basin, the Chrzano+s-O1Lvss basis and the 1laraex basin. ?herd art 50X1-HUM Sour active mines in the Bytom basin: Orzel Bialy, uarynski, ?tarchl.exaki, and Noxy Dwor. :'he Bolcslax Mine and the Clesansv Mine are in the Chrzanov - Ollct:~s basin, The only xork being done in the Tarnow basin is exploratory xork xith the aid oP geological drillings. The Bytom basin is the richest in zinc. Orzel Bia19? ~.- 7he~rzc~Bia].yrxorka-is made~p-vf-the~ine-,~r~sdiaeat -~uceasor,- ~ - - - - flotation processor, and a zinc ronndry. Dimly e~ctraction frot the ai.ne amounts to 1,200?tons of zinc ore ?-ith a content of 9 percent zinc, zinc sulphide, blends (ZnS), and 800 tons os eAl~{*+R ores -zinc amide. The blends ore is refined and enriched on the sediaent processor up to lei percent zinc and the galena (PbS) is separated mile t'se rest is ground in coal mills. All the ore passes on the tlotatiom nachiaery xhere zinc ore and blends xith a. content of S3 peroent zinc is obtdned. Ca':-smine ore extracted at the mine is sit`ted and eruahsd at the aechanical pra~cesaar and is passed to the rotary kilns of the fvondrp at the Otzel Hialy nine. 3. The 0rze1 Bialy works has ten rotary kilns. Dta3.ly prodnetion amounts to abut L20 tons of r7astan oocide in addition to 2G tons of rax lead and about eight tone of cadmium. !.. The zinc blends and pert of the galena are sent out toihe zinc mills at Szopier~ce (N 50-16, E 19-~r7), Qixice (Gleivit~ (2I 50-17, E 18-40), Lipid, and Kuneguadox (B 51-13, E 21-27). The remaining galena is processed in flu~naces for the purpose oP obtaining rax lead. The roasted oxide is transported ~+ narrow-image railroad to the mi11a beationad above, The cadmiva oxide is entirely transported to the Szopienice xorks, mere there is a cachoium refinery.
