Extraction of Tin and Copper by Acid Leaching of PCBs

2013-02-02  Nitric acid wa s found suitab le and used for the extraction of copper and tin at room temperature. In the leached solution suspended tin and copper nitrates were obtained. X-ray diffraction (XRD) and Energy dispersive X-ray analysis (EDAX) was done to characterize the precipitate obta ined. Copper in leached solution was recovered by cementation.

Leaching of gold from a free milling gold ore in copper ...

2020-08-15  The copper-citrate-thiosulfate system has some advantages over cyanidation, such as green, nontoxic and shorter leaching time, although a high leaching temperature above 70 °C is usually required to an acceptable gold extraction. Obviously, the system still needs to be further developed to ensure its commercial viability.

Leaching - Mining Fundamentals

Insitu leaching is also known as insitu recovery, or solution mining. This is especially used to extract copper and uranium. In this process, holes are drilled into the ore deposit by explosive or hydraulic fracturing methods. The leaching solution is then pumped through these channels.

Microbial Leaching of Copper from Waste Electronic Scraps ...

Microbial leaching was used to mobilize copper from two kinds of waste electronic scraps used as raw materials for printed wire boards. Both of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans used to solubilize copper from the samples. The experimental results demonstrated that the percentages of copper basically increased with decrease of sieve fraction of the samples.

show that the copper in electronic scrap was oxidised to Cu2+. The copper leaching rate was definitely influenced by the oxidant agent used. The copper‐bearing leachate can be purified and concentrated by solvent extraction processes and be used either as raw material for producing quite valuable copper salts, such as copper oxychloride [3Cu(OH)2*CuCl2], or as electrolyte for electrowinning ...

Recommended machining parameters for copper and copper

Machining copper alloys is considerably easier than machining steels or alumin-ium alloys of the same strength (see Figure 1). This is reflected in the signif-icantly lower cutting forces as shown in Figure 2. Unless specific technical requirements dictate the use of another material, free-cutting brass CuZn39Pb3 is the material of choice in contract turning and machining shops and CNC turning ...
