One of the main challenges facing the flotation of base metal oxide minerals is their fine sizes of particles as a result of fine grinding to achieve a desired degree of liberation for low-grade and finely disseminated complex ores. This study aims at studying hydrophobic aggregation and in situ gas nucleation of fine copper oxides with sodium dodecyl …
The separation system of the superconducting magnetic separator is shown in Figure 3. In the ready state, the power excitation is applied to the superconducting coil and the magnetic separator reaches a predetermined magnetic induction with an excitation time of less than 1 h. Once the superconducting magnetic separator reaches the predetermined
For instance, for the flotation separation of a ton of fine copper-molybdenum co-flotation concentrate to be used in this investigation, which assays around 26% Cu and 0.35% Mo with 90–92% mass below 50 μm, a sodium sulfide (Na 2 S) consumption of 20–30 kg was practically required for depression of chalcopyrite against …

The results indicated that 74.08% Cu was recovered by flotation, and the average grade of the copper concentrates was 21.68% (Table S-III, Supplementary …
The fresh copper oxide mineral surfaces exposed during crushing and grinding have a significant effect on subsequent flotation [23], [24], [25], [26].Many dangling bonds exist on fresh mineral surfaces because of destruction of the original lattice bonds, and the copper oxide mineral surface often shows strong polarity because of the …
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are ...
They mainly rely on increasing particle size by selective aggregation and decreasing the bubble size by using nano or microbubbles, but also on using reactor …

Fig. 1 displays XRD patterns for the copper slag, steel slag, chlorinated sample, and reduced sample. The copper slag mainly comprises fayalite (Fe 2 SiO 4), ferrous oxide (FeO) and magnetite (Fe 3 O 4); the steel slag is mainly composed of dicalcium silicate (Ca 2 SiO 4), tricalcium silicate (Ca 3 SiO 5) and calcium ferrite (Ca 2 …
The copper ions dissolved from the fine copper oxide were found to inadvertently activate fine silica flotation which could be effectively depressed by …
Abstract. Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of …
Jig separator (jig concentrator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. Jig separator are widely used in various heavy metal, metallic and …
The ore is Copper Sulfides with liberation size of 130 um, Pyrite of 100um and Magnetite of 160. since magnetite is the coarsest, can we place the magnetic separator before flotation. Our ball mill is set to produce a P80 of 150 um in the cyclone overflow? We also have Acid soluble copper oxide as
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

In addition to copper and nickel, this deposit is also a significant resource of cobalt, platinum-group metals, silver, and gold. Major metallurgical problems associated with these ores are separating the copper from nickel, recovering cobalt, and determining the distribution of platinum-group and other precious metals.
For copper oxide ores that contain weak magnetic copper-bearing minerals, such as libethenite, and copper-bearing limonite, after sulfidization flotation, the …
1. Introduction. Froth flotation was undoubtedly the most innovative and groundbreaking discovery for mining in the 19th century (Wills and Finch, 2015).Nevertheless, it did not last long that scientists recognized its limitations for extremely fine and coarse particles, which has remained a long-standing unsolved issue in the …
