Gold and Diamond Jig Mining: Overview and Techniques<\/p>\n
Jig mining is a highly effective gravity separation method used to recover gold and diamonds from alluvial deposits (riverbeds, placer deposits, or weathered ore). Jigs separate heavy minerals (like gold\/diamonds) from lighter materials (sand, gravel) using pulsating water flow and gravity.<\/p>\n

How Jig Mining Works
\n1. Principle:
\n – A jig machine uses a bed of particles (ore) subjected to repeated pulses of water.
\n – Dense minerals (gold\/diamonds) settle to the bottom (“concentrate”), while lighter waste material is washed away.<\/p>\n
2. Key Components:
\n – Screen\/Riffles: Traps heavy particles.
\n – Pulsation System: Creates up-and-down water movement (manual, hydraulic, or mechanical).
\n – Hutch: Collection area for concentrates.<\/p>\n

Types of Jigs Used
\n1. Pan American Jig: Traditional, simple design for small-scale mining.
\n2. Duplex\/Double Jig: Higher capacity for medium-scale operations.
\n3. Centrifugal Jigs: Modern, high-efficiency models (e.g., Kelsey or InLine Pressure Jig).
\n4. Manual\/Hand Jigs: Used by artisanal miners in Africa\/South America.<\/p>\n

Gold vs. Diamond Jigging
\n| Feature | Gold Jigging | Diamond Jigging |
\n|—————|—————————————|—————————————|
\n| Feed Size | Fine to medium sand\/gravel (<10mm). | Coarser material (up to 30mm). |
\n| Pulsation | Faster pulses for fine gold recovery. | Slower pulses for larger diamonds. |
\n| Bed Depth | Shallow bed for quick settling. | Deeper bed to retain larger stones. |
\n| Concentrate | Gold sinks with black sands (magnetite). | Diamonds mixed with heavy minerals (garnet, ilmenite). |<\/p>\n

Steps in Jig Mining
\n1. Ore Preparation:
\n – Remove large rocks\/slimes (clay) via screening\/washing.
\n2. Jig Operation:
\n – Feed slurry (ore + water) into the jig.
\n – Adjust water pulse speed\/stroke for optimal separation.
