Our characterization results show that this BCL copper slag is a good secondary source of base metals, especially iron and copper. These results reveal that the elemental proportion of iron was around 35.4%. Literature states that an iron grade that is considered viable for economic beneficiation should be at least 25% and this slag has …

Experimental investigation was conducted on a low-grade copper ore in Tajikistan with grade of 0.89% and oxidation rate of 99%, which belongs to refractory oxide copper with low-grade and high oxidation rate. According to the property of process mineralogy, using vulcanization xanthate flotation process, determined once rough concentration, three …

Extensive research has been carried out on the flotation of copper sulphide ore as compared to copper oxide and mixed type ores. Besides flotation, other beneficiation techniques (selective flocculation and gravity separation) are also discussed in the present review. A few novel pretreatment methods are currently being studied for copper ore ...

Study of collector dosage, pH and air flow rate in laboratory flotation machine in order to increase oxide copper recovery was done by (Saleh, A-H. M. At al., 2008) on Egyptian copper ore. Lee, K ...

Preceding pyrometallurgical processing, the copper content of ore-derived material is commonly increased. This is done by physicomechanical treatment in concentrators that use crushing, grinding ...

This last factor is often responsible for a significant part of the difficulties encountered in flotation. The dissemination of minerals can affect both the most abundant mineral, namely malachite, as well as secondary …

It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits.

In recent years, the demand for strategic metals like cobalt, nickel, and copper has greatly increased. Africa has attracted the attention of the world due to its rich Cu and Co resources, and its Cu-Co ore can be mainly divided into sulfide, oxide, and mixed. 1 Among those stages, acid leaching of valuable minerals from the ore is the key …
