The work done includes a mineralogical characterization (QEMSCAN), a Davis Tube magnetic test, an oxidation and activation test, 11 batch flotation tests, and a “locked cycle” flotation test.

A routine fecal flotation test may fail to detect these tiny cysts, which are shed inconsistently in the feces, and which often require a special zinc sulfate flotation solution for detection.

The batch flotation tests were done to determine the response of the mineralization to various grinds and flotation parameters, and to determine the process and flowsheet to be used for the locked cycle test.

The small-scale Flotation Testing has been key to understanding how the material may act in the mill, as well as estimating the recovery.
