Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...
The present invention relates to the recycling process of electronic waste resources to recover metals of value. More particularly, it relates to eco-friendly yet efficient hydrometallurgical processes to recover metal values from waste monolithic ceramic capacitors. In the proposed method, the source material such as mother boards having MLCC is pulverized using a ball …
Here's a bucket of crushed powder that I produced by running circuit boards through a ball mill and sieving it. The leftover small pieces of board that don't crush, but were worn 'clean', get leached in a separate bucket. You can clearly see metallics in the bucket. As well, you can see little 'plates' of scum.

The effect in this job is better ...
Study On Gold Extraction Process Of Printed Circuit Board. The printed circuit board is rich in recyclable metals Cu, Au, Ag, Pt, Pb, etc. The precious metals such as gold are extracted from it, which is in line with the concept of resource recycling. In this paper, the theorem method was used to extract gold from waste circuit boards.
The possible optimization of metal recovery from Printed Circuit Boards (PCBs) and Central Processing Units (CPUs) has been investigated. Usual …

This project deals with the experimental results of the leaching of Cu from Printed Circuit Boards (PCB) from obsolete electronic devices by means of leaching using different combinations of acidic mixtures followed by precipitation. Printed circuit boards were dismantled, cut into small pieces, and fed into a Ball mill.
These pyrolysed samples termed here as poly-cracked PCBs was then subjected to physical beneficiation process where controlled grinding was carried out using ball mill for liberation of associated metals from epoxies/polymers. The liberated metallic content was effectively separated from the non-metals by subsequent sieving.

For selective milling, the application of an impact mill (e.g., hammer mill) has been suggested to enhance the metal recovery from WEEE, including printed circuit boards (PCBs), e.g., reference [3
Way too expensive, for many reasons. He would burn everything. Then, he would ball mill, screen, melt the metallics, sample and assay the ash and the bars, and then ship it all to a primary copper smelter. Very, very simple. He would even throw pins into the melt. Most of you are having fun working the electronic scrap and playing with the ...
