Gravity Separation Equipment Suppliers, Saudi Arabia
Gravity separation equipment uses differences in particle density to concentrate heavy minerals from lighter gangue without chemicals. Technologies include jigs, spiral concentrators, shaking tables, centrifugal concentrators, and dense media separation (DMS) systems. In the GCC, gravity separation is applied in gold recovery, heavy mineral sands processing, and coal preparation, and is valued for its low environmental impact compared to chemical-based separation methods.

Gravity separation equipment leverages the density differential between valuable minerals and waste material to achieve physical concentration without chemical reagents. Established technologies include mineral jigs that pulse water through a bed of particles, spiral concentrators that use centrifugal and gravitational forces on a helical trough, shaking tables for fine-particle separation, Knelson and Falcon centrifugal concentrators for high-G recovery of free gold and heavy minerals, and dense media separation (DMS) plants that use ferrosilicon or magnetite suspensions to create a sink-float environment.
In the UAE and Saudi Arabia, gravity separation is deployed at alluvial and hard-rock gold operations, at heavy mineral sands projects recovering ilmenite, rutile, and zircon, and as a pre-concentration step to reduce feed tonnage to energy-intensive grinding and flotation circuits. Procurement managers should evaluate equipment based on feed particle size range, throughput capacity, concentration ratio, recovery rate, and water consumption. Gravity methods are environmentally preferred because they avoid the use of cyanide or other hazardous chemicals.
When sourcing gravity equipment for GCC projects, verify the supplier's ability to provide testwork on representative ore samples to predict performance and optimize equipment selection. Modular spiral and centrifugal concentrator plants can be rapidly deployed at exploration-stage projects for bulk sampling and feasibility assessment. Spare parts for wear components such as spiral liners, table decks, and bowl inserts should be available from regional stocks to minimize downtime during production campaigns.
