Properties of Fine-Grained Rock Waste from the Pilawa Gorna Amphibolite and Migmatite Aggregates Production Plant

In the course of mining and processing almost all petrographic varieties rock raw materials for production building materials, aggregates road railway construction, waste is generated. These are usually fine-grained fractions these rocks that difficult to manage deposited at dumps. The article presents describes results physical, chemical, mineralogical properties from amphibolite aggregate Pilawa Gorna in Lower Silesia (S-W Poland). Such studies have not been carried out on this before. tested a very dusty material (<0.100 mm) originating dedusting crushing classification operations during aggregates. Preliminary separation using collector-less flotation gravity also presented. Detailed chemical analysis shows most elements studied dust occur abundance close average Earth’s crust. collector-free investigated sample allows effective graphite part sulfide minerals Cu, Ni, Mo. presented may be basis further research development concept their economic use.
