## Abstract

A system for processing compounds having constituent materials of different mechanical characteristics to extract their constituent materials. The system includes a kinetic impactor configured to impact, via a shockwave, compound particles of a preimpact mixture, thereby creating a postimpact mixture including (i) subparticles of 1st-constituent-material and (ii) reduced-compound particles including a 2nd constituent material.

## Claims

### Claim 1

An impactor for kinetically impacting a compound material comprising constituent materials of different mechanical characteristics, the impactor comprising:
a chamber configured to be substantially filled with a liquid, the chamber comprising a peripheral wall including a wall-section with an interior surface having a non-planar shape; and
a shockwave generator located within the chamber and comprising a pair of gapped electrodes corresponding to the wall section,
wherein the shockwave generator is configured to generate a shockwave, via an electrical breakdown of the liquid in a gap between the pair of gapped electrodes, for impacting a preimpact mixture comprising a plurality of compound particles, wherein each compound particle comprises a first constituent material and a second constituent material;
wherein the non-planar shape of the interior surface of the wall-section and a position of the electrode gap with respect to the interior surface of the wall-section control a reflected shockwave's wavefront;
wherein the chamber comprises a first chamber and a second chamber coupled to the first chamber;
wherein the wall-section comprises (i) a first pair of oppositely located symmetrical wall-sections that form a part of the first chamber and (ii) a second pair of oppositely located symmetrical wall-sections that form a part of the second chamber wherein the shockwave is able to cause the first constituent material to separate from an at least one compound particle of the plurality of compound particles, resulting in a postimpact mixture comprising (i) an at least one first-constituent-material subparticle and (ii) an at least one reduced-compound particle comprising the second constituent material.

### Claim 2 (depends on 1)

The impactor of claim 1,
wherein each of the first chamber and the second chamber comprises an input and an output port.

### Claim 3 (depends on 1)

The impactor of claim 1,
wherein the pair of gapped electrodes comprises a plurality of pairs of gapped electrodes.
