Branicoda Copper Mine is considering opening up a new mining site. The geologists feel that there might be a lot of copper at this new site. Samples of ores taken from the new site were sent to Water Wagon Laboratories to be tested. The ore samples were recently added to a sulfuric acid solution to bring out the Cu2+ (copper(II) ions) into ...

Fortunately, calculating the copper wire recovery percentage is a fairly simple process. Simply take a small segment of cable and weigh it. Take note of that number and then strip the casing so that you are left with only the copper wire at the core of the cable. Weigh the copper by itself, then divide that number by the overall weight of the ...

The aim of the study was to recover copper and lead metal from waste printed circuit boards (PCBs). The electrowinning method is found to be an effective recycling process to recover copper and lead metal from printed circuit board wastes. In order to simplify the process with affordable equipment, a simple ammonical leaching operation method was adopted.
