EESTech’s proprietary R3 Process is a highly efficient comminution process that recycles mine site and process slag waste into smelt ready concentrates, with all post process tailing being transformed into inert sand products, resulting in zero-waste and environmentally sustainable outcomes.

EESTech’s R3 Process enhances the economic outcomes of the extractive metallurgy processes through the application ofa proprietary high speed counter flow rotary mill that particle shapes and reduce feed material to under 500 micron, liberating targeted resources from their matrix material.

Processed materials are screened into size fractions and separated by specific gravity to efficiently recover over 96% of the targeted resource in a single pass. All recovered resources are processed into smelt ready concentrates to deliver significant improvements in resource recovery.

The R3 Process incorporates a proprietary binary compound that reacts with the post process tailing to encapsulates it within an acid resistant matrix to produce inert high-grade sand products. The beneficiated tailing sand has been independently validated as a non-hazardous NEMWA Class 4 “inert” material, suitable and in demand for broad range of high volume downstream applications.

The R3 Process incorporates long service life equipment with successful operating histories in the oil, cement and minerals processing industries.
