Opis (eng)

Abstract: This paper presents the results obtained by determination of Bond rod mill work index (RWi), on a very low-grade copper ore, containing only 0.13% Cu. The standard Bond rod mill grindability test is performed in this research. RWi depends primarily on the mechanical properties of material conditioned by mineralogical composition and the desired particle size of the ground material. The mineralogical composition of the considered sample included the following metallic ore minerals: pyrite, chalcopyrite, hematite, magnetite, covelline, chalcocite, bornite, sphalerite and rutile. Tailings was presented by quartz, calcite, anhydrite, gypsum and clay minerals. The closing sieve size was 1,18 mm. The obtained value of RWi was 19 kWh/t, and therefore this ore can be classified as hard.
