There are a bunch of steps in the refining process. One of the first step is pulverizing/grinding where you can separate out the constituent components based on density. This step can done locally and will cut the volume of the ore by 75-90 percent. However, given the regulatory environment in the US surrounding refinement, there is likely a huge opportunity for innovation in this space.
