With the depletion of high-grade ores coupled with an increase in the global demand of Cu (Northey et al., 2014), researchers have turned their attention to the separation of chalcopyrite, the most abundant copper sulfide mineral, from lean grade ores (Ruth, 1995, Wang, 2005).However, due to the friability of siliceous ores such as Mpanda Mineral Field ore from …
A flotation pre-treatment study for the separation of enargite (Cu3AsS4) from chalcopyrite (CuFeS2) ores of different origins was investigated in this work.

Beneficiation of Egyptian Abu-Swayel copper ore by flotation 123 RESULTS AND DISCUSSION It is worth to mention that all tests were carried out at 200 g in one dm 3 i.e. at 20% solid/liquid ratio by wt., 250 mg/dm 3 pine oil as a frother and at1000 rpm impeller speed.
Low-grade ores are fine grained and tin values are highly disseminated in the ore body. Beneficiation of such ores creates a number of problems including fine tin losses in the tailing stream. Typical recovery values from the low-grade ores would not exceed 50–60% Sn by gravity units, hence a combination of gravity and flotation techniques ...

• Comminution, or crushing and grinding, to prepare the ore for the following separation steps. • Physical separation, or mineral dressing, or beneficiation, to separate the mineral(s) bearing the metal of interest from the other non-economic minerals in the ore, or gangue. This stage mayor may not precede the chemical separa
A comprehensive recovery process for the selective separation and enrichment of copper, zinc and iron minerals from a polymetallic ore was developed, which consisted of copper flotation, zinc flotation, and iron magnetic separation, and the adsorption mechanism of the copper collector Z-200 (O-isopropyl-N-ethyl thionocarbamate) was also studied in this work. The …
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in high-grade ores. This has resulted in a …
Chalcopyrite is the main mineral source of copper ore for extracting and producing copper. However, with the continuous mining of copper ore, the grade of chalcopyrite decreases year by year and its composition becomes more and more complex. The traditional pyrometallurgical extraction process has been unable to make efficient use of such resources, …
