He has made significant contributions to the field of materials science, particularly in the recovery of rare earth elements. His innovative approach addresses the challenges associated with extracting valuable resources from composite ores.

Latest Patents

Mackowski holds a patent for a process titled "Recovery of Rare Earth Elements." This patent outlines a method for recovering rare earth elements from a composite ore that includes monazite group minerals and apatite minerals. The process involves pre-leaching the composite ore with an acid to dissolve the apatite mineral into the leach liquor. Following this, rare earth elements are precipitated from the pre-leach liquor. The residue from the pre-leaching step undergoes an acid bake treatment, followed by a water leach to produce a water leach liquor rich in rare earth elements. Impurities such as thorium and iron are separated from the water leach liquor by introducing a neutralizing additive, allowing for the precipitation of rare earth elements from the post-neutralization liquor. Mackowski's innovative method is crucial for enhancing the efficiency of rare earth element recovery.
