1. A system for obtaining a mineral rich powder from an electronic waste substrate, the system comprising:
a shredder configured to receive the electronic waste substrate and cut the electronic waste substrate into a plurality of uniform fragments, wherein the shredder comprises one or more cutting shafts, wherein the one or more cutting shafts comprise cutting elements, and wherein the shredder comprises one or more apertures, comprising a grate or a screen, configured to retain the electronic waste substrate until a desired fragment size is achieved;
a mill, coupled to the shredder, including a container configured to receive the plurality of uniform fragments from the shredder, the container including a milling media, the mill configured to abrade the plurality of fragments with the milling media to produce a milled product;
a separator, coupled to the mill, configured to receive the milled product from the mill, the separator configured to apply a predetermined size selection to the milled product to provide a first output including a plurality of particles and a second output including a plurality of abraded fragments, wherein the separator comprises one or more sieves, and wherein the one or more sieves have a mesh size between No. 3 and No. 7; and
a skid coupled to and providing structural support for the shredder, the mill, and the separator, the skid comprising a frame with a plurality of upright members, a plurality of upper frame members, a plurality of lower frame members, and a solid bottom within the plurality of lower frame members.
