Ball milling recovers copper from old circuit boards C

2021-3-29  A new method for extracting copper from waste circuit boards takes advantage of ball milling, a brute-force means of jump-starting chemical reactions (Environ. Sci. Technol. 2019, DOI: 10.1021/acs.est.8b06081).

The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn’t float is called tailings because it goes out the “tail end” of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.

The results show that the sub-solution Cu-Cr alloy powders can be produced by high energy milling, in which Cr powders are first crushed into fine particulates, followed by the formation of Cr sub

Recovering copper from electric cable wastes using a

1997-1-1  After the electric cables were crushed by a cutter mill, small pieces of the cables were impact milled for the purpose of liberating the copper wire from the plastic covering. The shape of the copper wires was prepared for separation by shape at the same time. By impact milling, the copper wires were twined and became pill-like particles.

2021-3-24  Copper is extracted in large amounts from the Earth’s crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be

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 extracted the plasticizers from the PVC coverings of electric cables using organic solvents, and then crushed the obtained cable samples by ball milling.
