2022/4/13 Spiral concentrators are best suited for small-scale miners who want to process a large amount of gold at one time. They are also a good option for those who cannot afford more expensive gold extraction methods. If you fit into either of these categories, a gold spiral concentrator could be the right choice.

INTRODUCTION Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used to treat chromite ore in 1943. Later in 1943, its use was extended to the mineral sand beneficiation.

Spiral concentrators are widely applied to beneficiate commodities such as Cr 2 O 3, mineral sands, and ferrochrome. The application of spirals for heavy minerals has been limited to a feed top size of 1 mm. At particle sizes larger than this, friction retards heavy particles and the particles' primary
