Minerals

mineralsAlthough MRC’s initial focus is in the coal industry, our technology has applications throughout mineral markets such as copper, lead, zinc, and silver mining operations. Initial laboratory tests on chalcopyrite ore in a copper mill have shown increased recovery using the HHS Process over conventional froth flotation. Due to the high value of these minerals, even a small recovery from ultrafine material could result in a high value of additional minerals and revenue.

The HHS Process can be used for mineral separation by rendering one-type of mineral hydrophobic and keeping other minerals hydrophilic. In principle, the process is similar to solvent extraction, which is widely used for the recovery of metallic ions from solution. Therefore, the HHS process can be used to recover particles that are well below the lower particle size limit of flotation, as shown in the figure on the right.
