As for the Jinchuan mixed Cu Ni ore, pentlandite is commonly associated with pyrrhotite, pyrite, and chalcopyrite [4]. The mixed sulfide ores are readily oxidized, which has an adverse effect on the flotation process in Jinchuan. However, there is little literature referring to the effect of surface oxidation on mixed Cu Ni ore flotation ...
The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world.
This report describes the results obtained from separating mattes smelted from Duluth Gabbro bulk flotation concentrates into copper-rich and nickel-rich fractions by mineral dressing techniques. In conventional processing of mixed sulfide ores of copper and nickel, the separation of copper from nickel begins in the ore beneficiation plant.
Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved …

The mining and mineral processing of Cu-Ni-PGM sulfide ores in South Africa occurs in semi-arid regions. The scarcity of water resources in these regions has become one of the biggest challenges faced by mineral concentrators. As a result, concentrators are forced to find ways through which they can manage and control their …
It is widely acknowledged that chalcopyrite, which is a copper-bearing sulfide mineral, has a fast rate of flotation, while pentlandite, a primary carrier of nickel in sulfide Cu-Ni-PGM ores, floats relatively slowly compared to other sulfide minerals in Cu-Ni-PGM ores (Becker et al., 2009, Corin et al., 2011).
The recent nickel grade range can be as low as 1.0–1.20%. The ore grades at Raglan and Voisey's Bay are much higher than in the Sudbury region. However, since the production from Nickel Rim South Mine was brought online, Glencore's flotation plant Strathcona started processing a higher grade ore with 1.57% Ni and 2.85% Cu ().
The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a concentrate which is then smelted to produce a nickel-enriched phase called matte, and further refined to ...

Earlier studies at the Kevitsa Cu-Ni concentrator plant have indicated that seasonal variations of the properties of the process water affect the oxidation of the surface of the minerals, and ...
The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide …
ore, we can provide collectors for the slime flotation step needed prior to potash flotation. We also offer collectors for reverse flotation where halite is floated to beneficiate …
The highest extractions of 86.2 % for Ni and 79.7 % for Co were achieved by leaching at glycine/(Ni + Cu) molar ratio of 4, DO of 15 ppm, pH of 10.2 (adjusted with ammonia), 10 % solids and 30 °C ...
Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes. Extracting Lithium from its …
Cu kinetic flotation tests were conducted following the standard flotation procedure used in the plant (Fig. 2) and using tap water (TW, sulphate ~ 250 mg/L) or tap water containing higher amounts ...
Introduction. Kevitsa Mining Oy is a Ni–Cu–PGE project in Finland and is owned by First Quantum Minerals. The deposit was acquired from Scandinavian …
Intimate knowledge of the mineralogical assembly of the Yushui complex ore rich in Cu, Pb, and Ag is essential if efficient separation processing is to be conducted. With the aid of testing instruments, such as scanning electron microscope (SEM), X-ray diffractometer (XRD), and mineral liberation analyzer (MLA) combined with energy …
Magmatic Cu-Ni-PGM sulphide deposits, IOCG deposits, VMS deposits, ... Mining and processing wastes can contain: i) primary ore in subeconomic concentrations, ii) gangue minerals, ... In fluidised bed flotation, processing feed is introduced into a cell that contains a bed of particles as well as gently uprising water. Air bubbles are …
The successful implementation of the flotation process not only depends on the physical and chemical properties of the ore, but is also affected by a variety of operating conditions. Therefore, understanding the influencing …
This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc.) which may or may not contain precious metals. These ore deposits are called polymetallic by …
