Mineral processing Wikipedia
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of goldGravity separation techniques have been in use in the mineral sands industry for decades; from the Reichert cone to Wilfley tables, Wright sluices and the Kelsey Jig, all attempting that elusive perfect gravity separation Just as the gravity separation industry evolved, Richards Bay Minerals also evolved in their use and approach to gravity A history of gravity separation at Richards Bay MineralsChapter overview 2 weeks 'Mixtures' was first introduced in Gr 6, so learners should already be familiar with these concepts Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography)Methods Of Physical Separation Separating Mixtures
