Ore may move from crushing, screening or drying equipment into storage before being transported by truck to a mineral-processing plant.

During this route, an FIBC may be filled, lifted, placed on the ground, loaded into a vehicle, exposed to road vibration and lifted again at the destination.

The bag is therefore affected by more than the static weight of the ore. Braking, turning, repeated lifting, road vibration and contact between adjacent bags can change the forces applied to the fabric, seams and lifting loops.

An FIBC for ore transportation should be evaluated according to material condition, body construction, lifting equipment, moisture exposure, vehicle arrangement and pre-shipment inspection.

Confirm the Ore Condition Before Transport

Crushed ore, screened granules, mineral powder and damp material should not automatically use the same packaging configuration.

Large or sharp-edged particles may rub against the body during filling and road vibration. This can increase local abrasion and puncture risks.

Drop height should be controlled during filling, and a representative material trial should be completed where sharp particles are involved.

Fine mineral powder may escape through woven gaps or sewing needle holes. Continuous vibration on a long transport route may also move fine particles toward the body seams.

Coated fabric, a PE liner or sift-resistant seams should be evaluated according to particle size and the permitted leakage level.

Moisture content must also be checked. An uncoated FIBC has no verified waterproof performance and should not be treated as leak-proof packaging for material containing free water.

Match the Body Specification to the Transport Load

Ore frequently has a high bulk density. A bag may reach its weight limit before the full body volume is used.

Each bag should be filled using a weighing system. Visual fill level should not be the only method used to determine when filling must stop.

For reference, one 1200 kg mineral FIBC configuration uses nominal dimensions of 90 × 90 × 90 cm and 180 g/m² uncoated fabric.

Its warp and weft fabric strengths are both specified at ≥1600 N. These figures provide material-level requirements but do not independently establish a complete-bag safety factor.

The dimensions of the filled bag should also be measured. The nominal dimensions describe the unfilled specification, while the body may expand after loading.

Actual filled dimensions affect pallet selection, vehicle arrangement, warehouse space and clearance during unloading.

Match the Four Lifting Loops to the Equipment

Ore FIBCs are commonly loaded and unloaded using forklifts or other suitable lifting systems. Loop quantity, position and effective height must match the equipment.

The reference product uses four soft side-seam lifting loops. The loop specification is 7 × 145 cm, with a linear weight of 50 g/m and specified strength of ≥18000 N.

The meaning of the 145 cm measurement should be confirmed as a production or cutting dimension. It should not automatically be described as the effective loop height.

All designated loops should be used during handling. Lifting a filled four-loop bag with only one or two loops changes the intended load distribution and can increase local forces.

Forklift tines should be smooth and free from burrs or sharp edges. They should be removed only after the bag is fully supported and the load on the loops has been released.

Control Movement and Contact Inside the Vehicle

Filled FIBCs should be positioned to limit movement during braking, turning and road vibration.

The vehicle floor should be level and free from screws, metal edges, stones and other objects that could puncture or abrade the body.

If pallets are used, check for broken boards, exposed nails and gaps that could create concentrated support points.

Restraints should limit movement without cutting into the body or compressing the lifting loops. A narrow strap applying high local pressure may damage the fabric.

Stacking should not be determined only by the visible shape of the filled bags. Where no stacking design or test evidence is available, multi-level stacking should not be assumed suitable.

Include Weather Protection and Identification

Standard uncoated fabric has no verified moisture-barrier performance. Rain entering the bag may change the net weight, flow behavior and subsequent discharge condition of the ore.

Open vehicles, outdoor loading and long waiting periods may require weather covers, a liner or a verified coated FIBC.

Labels should identify the ore, grade, production batch and net weight according to the order requirements.

Clear identification is particularly important when different particle grades or mineral types are transported in the same vehicle or stored in the same warehouse.

Where the material is classified as dangerous goods, the applicable UN packaging code, test documents and compliant markings must be confirmed separately.

Complete a Pre-Shipment Inspection

Before loading, inspect the body for holes, cuts, excessive abrasion and opening seams. Loop attachment areas should not show broken thread, incomplete stitching or visible fabric damage.

All four loops should be present and free from cuts, severe abrasion, knots and permanent deformation. A clear difference in loop length requires additional investigation before lifting.

The actual filling weight, label, top closure and filled dimensions should also be checked. If a liner is required, confirm that it is undamaged and properly closed.

For long-distance transport, loading photographs, batch records and inspection results can support comparison with the packaging condition at the destination.
