flotation tests, in order to determine the effectiveness of the resin-flotation procedure on such ores. To obtain a broad coverage of the field of application, three different metal-bearing ores were investigated: (1) a basemetal ore, - such as an oxide-copper ore containing quartz-sericite schist and granite as primary gangue constituents; (2 ...

Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its …

Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

Preconcentration of Primary Uranium Ores by Flotation by Burt C. Mariacher E XTRACTION of uranium from ores is being ac- complished by processes which, for the most part, subject the entire ore to acid or carbonate leaching. Ore deposits with a U,O, content below 0.10 pct U,O, are seldom considered suitable for treatment by leaching.

The flotation tests were carried out on the ground mixed ore sample using a conventional Agitair LA-500 stainless steel flotation cell (1.75 L), specifically designed to avoid particle settling and entrainment (Filippov et al., 2016).For each experiment, a pulp sample of 90 g dry mixed ore sample was mixed into the cell with water at 800 rpm to obtain a 20 wt% solid …

Recent focus on hydrometallurgical methods for non-sulfide copper ores prompted a study on leaching a copper oxide ore containing 2.22% Cu, 44.9% SiO2, 6.94% Al, 6.61% Fe, 6.25% Mg, 3.67% Ca, and 1.7% Na with H2SO4 for gaining insight into the behavior of impurities in the leaching process. The effects of leaching time (30–180 min), acid concentration (0.25–2 …

Optimisation of gold recovery by selective gold flotation for copper-gold-pyrite ores. ... An investigation into the effects of various flotation parameters on the flotation behavior of pyrite, gold and uranium contained in the Witatersrand Type ores and their practical exploitation. International Conference on Gold (1986), pp. 505-525.

In this study the mineralogy of an untreated and pre-treated uranium ore was investigated using synchrotron and non-synchrotron X-ray diffraction. The results obtained from standard X-ray …

It has also shown benefits in bench tests using ore from the Yakabindie nickel deposit and from the Olympic Dam copper–uranium mine. A key issue that remains for nickel flotation is the poor response at sizes below about 10 μm.

A Mo-copper concentrate with Mo grade of 3.02% and recovery of 93.46% was obtained through the close-circuit flotation test, which satisfy the requirement for the bulk flotation of Mo-copper ore. View

Other metals were not extracted and were present in leach solution. The 74 ± 3.7% uranium from concentrated of leach solution from copper ore and 79 ± 4% of uranium from flotation waste was recovered. With uranium other precious metals was recovered also.

Five different materials were examined as a potential source of uranium: phosphate rocks, phosphogypsum, copper ore, flotation tailing from the copper industry and waste from Gilów, tailing pond (Poland). Phosphate rocks, in …

copper ores compared to the gold ores (RY1 and SYW1) which are marginally low, indicating uranium is less associated with gold. Of the copper rich ore samples, uranium levels are high in RGY1 with moderate amounts in RG8 and RR7. RRG4 is the only high grade ore fairly low in …

will centre on the Witwatersrand ores; while flotation is important in the treatment of the arsenopyritic gold ores of the Barberton area, the economic importance of that area is too slight to justify detailed treatment. Similarly, the role of flotation in the production of uranium at Palabora is ignored. Flotation of Pyrite
