1. Gravity Separation. Gravity separation is most suitable for processing placer rutile ore. In separating primary rutile ore, gravity separation is often essential for enrichment. In sorting rutile ore, gravity separation desliming and tailings are used as roughing operations, which can discard most of the slime.
