Current Status of Copper-Ore Processing: A Review
The rougher bulk concentrate contains 4% copper with 75% recovery. After recleaning, the final copper con-centrate produced contains at least 20% copper with 85% recovery. The plant within the Tominskii MPE produces 28 million t of porphyry copper ore per year, where the initial content of copper in the ores is 0.4%.

A New Collector for Effectively Increasing Recovery in Copper Oxide Ore …
For instance, the fine-grained copper oxide ore is poorly floatable and displays a lower recovery during the flotation process [7]. Up to now, sulfide flotation is still one of the most widely used processes in copper oxide ore dressing, but it is unable to solve the problem of low recovery of micro-fine oxidized copper ores [8,9].

Novel treatment for mixed copper ores: Leaching ammonia
Oxide and/or mixed ore flotation are separated into two distinct treatments: (i) direct flotation and (ii) sulfating flotation (controlled by potential sulfidation). The collectors for direct flotation are fatty acids (oleic acids, sodium oleate), fatty amines, petroleum sulfonate, and hydroxyl acids ( Deng and Chen, 1991, Li et al., 2015 ).

Quick Look At The Copper Ore Flotation Method
The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging useless minerals (gangue minerals) in the slurry as tailings are called forward flotation. Otherwise, it is called anti-flotation. Copper is one of the important non-ferrous metals. In the …

Practical aspects of oxide copper recovery with alkyl hydroxamates
Dekun et al. (1984) and Rule (1982) described the use of hydroxamic acids for natural ore flotation of oxide copper ores. It is evident that much of the published literature deals with mechanistic aspects of hydroxamate interaction with oxide minerals and laboratory flotation of single minerals. Although, there is little useful information in ...

Flotation of Copper oxide ore
For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is easy to float, and copper oxide can not be recovered by a single flotation method. Copper oxide minerals in a separate state are called free ...

The Extraction of Copper
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation).

Treatment of Mixed Sulfide Oxide Ores of Copper
Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide minerals are considered satisfactory, using modern flotation ...
