ORE SORTING AND GRAVITY
Zircon from mineral sands tailings
Holman-Wilfley, with alliance partner MD Mineral Technologies of Richards Bay, South Africa, acknowledge their successful involvement with Tronox Ltd at the Namakwa Sands Wet Gravity Extension Project. The plant has been commissioned at the Namakwa MSP operations site ~ 15km from Lutzville, South Africa(~ 350km north of Cape Town). The project design is based on a gravity zircon recovery circuit from tailings.
After classification, zircon is concentrated using MD Mineral Technologies VHGS Spirals, with final concentration on 21 x Holman 8000DD gravity tables.
The circuit was installed and commissioned on schedule in early 2016, and Senior Tronox Project Team member – Frans Huisamen stated:“ The project is a great success, and we are delighted with the additional revenue benefits to the Namakwa Operations.”
Holman Wilfley Director Chris Bailey said:“ We are proud to have been associated with Tronox, and with our partners, MD Mineral Technologies, on this exciting project. We believe our Holman concentrating tables have once again demonstrated their potential to quickly add value to gravity processes.”
Tronox’ s TiO 2 business mines and processes titanium ore, zircon and other minerals, and manufactures TiO 2 pigments. The business operates mines and mineral processing plants in
South Africa and Australia, and pigment manufacturing plants in the US, the Netherlands, and Australia.
Holman-Wilfley is an established global market leader in gravity table supply. Its new factory site is in Cornwall, UK – once the heart of the world tin mining Industry, and currently experiencing a resurgence in prospecting activity.
The company says“ the Holman table is unique among its market competitors both from

appearance( design layout) and from its separation capability. It often easily outperforms alternatives. In the last four to five years ~ 80 % of product sales have been to overseas project locations, including Russia, South Africa, Mozambique, Australia etc. Applications include titanium bearing heavy mineral sands, tantalum, tin, tungsten, chromite, gold.
