Copper extraction Wikipedia

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wetted, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic. Typical reagents include potassium ethylxanthate and sodium ethylxanthate, but

Recommended machining parameters for copper and copper alloys

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

General tips on milling/turning copper

26/04/2012· HSS tool bits actually work very well when machining copper. Trick is to have a large swooping radius on the top face of the tool ( like this --> ) but rotated 90°) and a steep cutting angle of 20° or higher. After grinding, hone the cutting edges sharp with an India stone. Works great, but needs lubricant as suggested above. 04-22-2012, 01:29 AM #8. jmcvo. View Profile View Forum Posts Cast

Understanding Grades of Copper Scrap ASM Metal

The most valuable type of copper pipe clean copper tubing may qualify as #1 copper as long as it is free of fittings, insulation, paint, solder and other materials. In fact, most copper tubing and copper pipes can be of #1 grade providing they show few signs of corrosion and have their fittings removed. Trace amounts of oxidation on the tubing are generally acceptable.

Simultaneous recovery of high-purity copper and polyvinyl

Herein, we introduce a combination of plasticizer extraction from polyvinyl chloride (PVC) and ball milling for the simultaneous, effective recovery of PVC and copper (Cu) from thin electric cables. PVC coverings typically contain plasticizers for flexibility. As such, PVC cables become brittle after plasticizer extraction, causing them to be easily crushed by physical impact. Hence, we

Copper mining in the United States Wikipedia

The rock with less copper was called milling ore, or concentrating ore, and required crushing and separation of ore minerals from the waste rock to produce copper concentrate, which was sent to the smelter. Because metallic minerals have higher specific gravities than most gangue (waste) minerals, concentrating the milling ore was done in various gravity classifiers. The early Michigan copper
