Bulk Iron Ore Concentrates Shipping

Bulk Iron Ore Concentrates Shipping

Concentrated Ores known as Concentrates are produced in two distinct methods:

  1. Dry Method
  2. Wet Method

Dry method concentrates production involves the crushing of high-grade ore and removing waste material, leaving powdered ore with a low moisture content. During the crushing process, air is introduced into the powder with the result that, if the product becomes damp, this oxygen may react with the sulphur content of the ore to produce heat.

In addition to this difficulty, oxygen ingress to cargo compartments stimulates self-heating of concentrates and ventilation should therefore be avoided, perhaps reducing oxidation still further by mechanically compressing the cargo and/or covering same with plastic sheeting. Furthermore, metallic elements present in such concentrates may emit explosive and/or toxic gases. Thus, extreme care should be exercised when entering a cargo compartment containing concentrates, bearing in mind that the compartment is likely to be short of oxygen. Even if dry, the dust of concentrates produced by the dry method may be toxic if inhaled or if allowed to touch skin.

Wet method concentrates production involves the water flotation process. Material consists of the sulphide portion of the ore separated from crushed rock by a water flotation process. Therefore, containing water which may liquefy and shift dangerously across the ship’s hold due to moisture migration. It is crucial that the moisture content of concentrate cargoes be analyzed and checked prior to shipment and refused if this analysis reveals that the moisture content of the concentrate is too high.

Even though, concentrates shipped dry, there is danger inherent in the practice of spraying water over concentrates to cool. IMO (International Maritime Organization) Code of Safe Practice for Solid Bulk Cargoes lays down that a certificate stating the relevant characteristics of the material to be loaded should be provided at the loading port, incorporating also the Transportable Moisture Limit (TML), and reference to IMO (International Maritime Organization) recommendations should be stipulated in any charterparty or sale contract involving concentrates. For example, a clause should be stipulated in charterparty:

“Carriage of concentrates to comply with IMO (International Maritime Organization), local and international regulations and recommendations”
