6 ALS Metallurgy - Mineral Sands Process Development Heavy Liquid Separation This type of gravity separation is also known as “sink-float” separation. The heavier particles will sink and effect sharp separation of the heavy and light particles. In practice, the dense media (i.e. bromoform at 2.84-2.89, tetrabromomethane

Heavy minerals. Most sands are composed for 99% of light minerals such as quartz (s.g. 2.65) and feldspar (s.g. 2.54 – 2.76). Therefore, sands are mainly distinguished on the basis of their variable heavy mineral content. Heavy minerals are considered to be those minerals with a specific density greater than 2.8. Separation

The heavy mineral deposit occupies a coastal strip varying between 50m and 300m wide. The deposit is divided into three geological zones – Tidal Zone, Beach Zone and Berm Zone – however under this project, only heavy minerals in beach and berm zones will be mined with heavy minerals within the tidal zone not mined, the report said.

The heavy mineral is separated from the quartz sand. In the case of spiral technology, the spiral troughs are angled and the heavy mineral sand moves to the inside and the lighter gangue minerals to the outside of the trough as the slurry travels down the spiral. Repulpers on the spirals aid in the recovery process.

Eneabba mineral sands mining operation (Figure 1 ). The Eneabba West deposit is estimated to contain 200 million tonnes of ore at an average grade of 3% heavy mineral, which will be mined over a period of approximately 14 years. Mining of the deposit would be carried out using a bucketwheel dredge which will float on a

Moreover, heavy mineral processing plants are currently well-established and highly mechanized, with considerable separation efficiency . Usually, heavy minerals from beach sands are concentrated by physical methods, first involving gravity separation, followed by the combination of magnetic and electrostatic separation [5,6,7,8].

Coburn HMS Project 1. General Background. Heavy minerals, such as zircon, titanium dioxide minerals, garnet, sillimanite, kyanite, and staurolite, are eroded from their parent igneous or metamorphic rocks and are transported by water and/or wind action over long periods of geological time, often ending up in the same locations as placer deposits.When such deposits
