Recovery of titanium from beach sand by physical …
Wet spiral concentrators are employed to separate light fragments like quartz and fine seashells from the heavy minerals. Ilmenite is recovered from the concentrate using wet magnetic separation, after drying, the non-magnetic concentrate is passed through electrostatic separators to separate rutile and zircon (Lanka Mineral Sand Ltd., 1999).
