The Jigger Machine, also known as a Jig Separator, is one of the oldest and most reliable gravity-based mineral processing equipment used for separating minerals based on differences in density, particle size, and shape. It operates on the principle of jigging, where a pulsating water current stratifies mineral particles in a vertical water column, allowing denser minerals to settle at the bottom while lighter ones are carried away.
Jiggers are widely used in gold, tin, iron, coal, diamond, and heavy mineral processing due to their high efficiency, low operating cost, and simple operation.
- Primary Use: Separating native gold, placer gold, and gold-bearing sulfides from quartz and gangue minerals.
- Advantage: High recovery rate for coarse and fine gold (down to 0.1 mm).
- Industries: Artisanal mining, alluvial gold processing.
- Target Minerals: Cassiterite (SnO₂), wolframite (Fe,Mn)WO₄.
- Process: Heavy minerals settle at the bottom while lighter minerals are washed away.
- Industries: Tin mining (Malaysia, Indonesia), tungsten extraction (China, Bolivia).
- Application: Upgrading hematite, magnetite, and limonite ores by removing silica and alumina.
- Process: Dense iron minerals are concentrated while lighter gangue is removed.
- Industries: Steel production, iron ore mines.
- Target Minerals: Diamonds, ilmenite, rutile, zircon, garnet.
- Process: Heavy minerals settle while lighter gangue is washed away.
- Industries: Diamond mining, titanium/zircon processing.
● Gold and precious metals: Recover coarse gold particles (19.3 g/cm³) from alluvial deposits or hard rock ore tailings. Their ability to process larger particles complements finer separation methods like shaking tables.
● Coal beneficiation: Jiggers are widely used to separate clean coal (density ~1.3–1.4 g/cm³) from shale and pyrite (density ~2.5–5.0 g/cm³). They remove impurities, reducing ash content and improving coal quality for combustion or coking.
● Iron ore processing: Concentrate hematite (5.26 g/cm³) and magnetite (5.18 g/cm³) from silica-rich gangue. Jiggers efficiently handle coarse iron ore particles, upgrading low-grade ores to meet smelting requirements.
● Tin and tungsten ores: Separate dense cassiterite (6.9–7.1 g/cm³) and wolframite (7.0–7.5 g/cm³) from lighter silicates. Jiggers are particularly effective in pre-concentrating these ores before further processing.
● Base metals: Concentrate lead (galena, 7.5 g/cm³) and zinc (sphalerite, 4.0–4.2 g/cm³) ores from gangue, reducing the load on downstream flotation processes.
