Abstract The Ni-Cu-platinum group element (PGE) sulfide mineralization in the 1.85 Ga Sudbury impact structure occurs two discrete environments: (1) along or near basal contact, including disseminated to semimassive an inclusion-rich sublayer, fragmental underlying anatectic footwall breccia, and veins disseminations pseudotachylitic (2) inclusion-bearing quartz diorite phase of radial concentr...

The enrichment of polymetallic sulfide ore is a complex task. Fine grinding carried out to reveal useful minerals, resulting in the formation microparticles. It difficult achieve floatation microparticles and fine minerals are lost with flotation tailings. problem microparticle can be solved by using air bubbles smaller than 50 µmin for process. Water-air microemulsion (WAME)of frothersolution ...

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...

The purpose of this study is to propose the flotation procedure seafloor massive sulfide (SMS) ores separate chalcopyrite and galena as froth sphalerite, pyrite, other gangue minerals tailings, which currently facing difficulties due presence water-soluble compounds. obtained SMS ore sample contains CuFeS2, ZnS, FeS2, SiO2, BaSO4 in addition PbS PbSO4 Pb minerals. Soluble compounds releasing Pb...

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, particles are concentrated froth, and associated gangue minerals separated as tailings. However, significant amount of lost into tailings during the processing; therefore, can be considered secondary resources or future deposits copper. Particle–bubble collision efficiency particle–bubble aggreg...

Abstract The paper comprises new analytical data on the nature and occurrence of gold in solid pyrobitumen, closely associated with main gold-bearing sulfide arsenic ores Bakyrchik deposit (Kazakhstan), related to post-collisional magmatic-hydrothermal origin. Gold mineralization occurs mainly form an “invisible” type structures arsenian pyrite arsenopyrite, gold-organic compounds pyrobitumen c...
