Flotation and Screening Recovery of Titanium Minerals from a Monazite Mineral Sands Circuit

Investigations were undertaken to assess the suitability of CSIRO
flotation methods for improving the efficiency of separation of heavy
minerals in the monazite circuit at the Westralian Sands Limited
operations at Capel, Western Australia. Flotation work was conducted on two plant samples. The first was a high-titanium product containing considerable amounts of zircon and silica as quartz and aluminosilicates, and the second was a low monazite/zircon material containing high levels of silica.
A three-stage process including reverse flotation was developed to
treat the first sample. In this process monazite, zircon, quartz, and
aluminosilicates were selectively concentrated by flotation and screening to produce a titanium-rich product. In the first stage, an acid amine float, monazite, zircon, and some non-zircon silica were recovered and in the second stage, an alkaline amine float using a fluoride activator, more quartz and staurolite were floated. The titanium minerals were thus concentrated in the unfloated fraction. In the third stage, the titanium-rich flotation tail was screened at 250 m to remove the remaining coarse aluminosilicates. In a single pass, the three-stage process yielded a TiO2 recovery of 64.0 per cent with the titanium-rich product assaying 70.3 per cent TiO2.
