Product Details

Submarine Tin Alluvial Ore Production Line Solution is a specialized system for offshore mining and beneficiation.

This solution adopts a logistic model of "Offshore Pre-treatment + Onshore Purification". It integrates high-power sand pumping, shipboard screening, and jigging to process massive volumes (up to 1500t/h), reducing logistics costs by 60%.

What Is Submarine Tin Mining?

Submarine Alluvial Tin Mining involves extracting Cassiterite (Tin ore) from the seabed. Unlike land mining, space on the mining vessel is limited. Therefore, the process focuses on Volume Reduction: discarding 90% of waste sand at sea using compact Jigs, and transporting only the heavy rough concentrate to land for final cleaning.

Submarine Tin Beneficiation Process

Phase 1: Marine Operation (Shipboard)

Goal: Massive volume reduction and roughing.

Extraction: High-power Sand Pumps extract seabed material.
Screening: Trommel Screen removes large coral reefs, shells, and gravel.
Roughing: Jig Machines (Circular or Sawtooth) separate heavy tin minerals from light sea sand. Waste sand is discharged back to the sea.

Phase 2: Land-based Operation (Onshore)

Goal: Final purification to market grade.

Transport: Rough concentrate is barged to the shore plant.
Concentration: Shaking Tables provide precise separation to upgrade tin content to ≥ 60%.
Tailings: Onshore tailings can be dry-stacked or treated.

Frequently Asked Questions (FAQ)

Q1: How do you handle corrosion?

A: Seawater is highly corrosive. All our shipboard equipment (Trommels, Jigs) is treated with specialized marine-grade anti-corrosion paints and utilizes stainless steel or rubber linings where applicable.

Q2: Why use Jigs on the ship instead of Spirals?

A: Jigs are more compact per ton of capacity and handle the swaying motion of a ship better than Spiral Chutes, which require a stable level to operate efficiently.

Q3: Can this system handle varying weather conditions?

A: Yes. The modular shipboard system is designed with stability in mind to withstand wind and waves typical of offshore operations.
