UNDERSTANDING LIQUEFACTION IN NICKEL ORE. Liquefaction of nickel ore is a longstanding issue in the shipping industry, especially when stored in wet conditions at loading ports. Liquefaction occurs when the MC in cargoes, such as nickel ore, is above the TML. Contributing factors include: The ship's motion- causing cargo compaction
Abstract Nickel is mostly extracted from sulfide ores, however, laterite ores account for over 60 pct of all nickel resources in the world, and despite its predominance, there is no well-established process to extract nickel from such ores. Nickel in laterites is hosted in many different compounds such as oxides, hydroxides, and silicates minerals. The sulfation-roasting …
Closely monitoring moisture content of the cargo during loading and carefully managing navigation during passage are the best practices for preventing liquefaction incidents in nickel ore shipments.
Nickel ore varies in colour. There are several types of ore of variable particle size and moisture content. ... .1 the moisture content of the cargo shall be kept less than its TML during loading operations and the voyage; ... The bilge system of a cargo space to which this cargo is to be loaded shall be tested to ensure that it is working. ...
Indonesia has tightened nickel-ore quotas and cracked down on illegal mining. There is a domestic ore shortage. Ore shipments have fallen by more than a third this year, according to Jim Lennon of ...
of ore with 1.8% Ni and moisture 25% are needed. (75 000 tons dry ore x1.8%Ni = 1 350 tons Ni). This means 3 300 tons of ore per day is being processed (130 trucks of 25 tons each). 1 350 t nickel, that is 45 t nickel per day, are produced from this quantity of ore. However, our product is not only nickel, but an alloy made of 20%Ni and 80% Fe.
Through long weathering processes, Ni2+ replaces Mg2+ and Fe2+ in the lattice of corresponding silicates and ferric iron oxides, and is closely in conjunction with iron oxide and silicate minerals [8]. The concentration of nickel in an ore-body is very low, and typical nickel content in Chinese laterite ore is less than 1%.
with the carriage of nickel ore. Newly discovered nickel ore mines are being operated by owners who have little or no experience of the mineral's properties or shipment. The locations of the new mines are proving too remote for the attendance of surveyors, and there is a lack of reliable laboratories for testing. As new deposits are found
The data source of this paper is the UN Comtrade database. We use the international nickel ore trade data from 2009 to 2018 with the Harmonized System code of 260400, including nickel ore sand and its concentration. The data were obtained on December 2, 2019. We obtained the nickel ore trade data from 152 countries and regions covering ten years.

Nickel ore is a cargo that may liquefy if the Moisture Content (MC) exceeds the Transportable Moisture Limit (TML). The point at which the cargo can begin to act like a liquid is when the Flow Moisture Point (FMP) is …

Ballast system in 5C-3-A3/9.17 If two or more pieces of loading/unloading equipment are used for simultaneous loading/unloading, the intermediate strength checks are to be carried out based on the same principle in 5C-3-A3/9.11 of the
Report on nickel ore cargoes Philippines 2020 SURIGAO – main area for shipment of nickel ore Surigao and the surrounding islands are the most popular location for loading nickel ore, there are no facilities for loading at the actual port of Surigao which is a small provincial port, but
Because of the rapid rise at the rate of approximately 4.7% per year in stainless steel demand (Norgate and Jahanshahi, 2011), nickel sulfide ore has been rapidly exploited in recent years, accelerating the depletion of nickel sulfide ore, so that mixed oxide-sulfide nickel ore is becoming the major source of the nickel product in nickel ...
In reference (Class, 2012), to test the fluidity of nickel ore samples, the static incline test with different MCs was carried out.As shown in Fig. 4, the fluidity of nickel ore with 12 groups of MCs could be observed when the box (0.50 m × 0.50 m × 0.50 m) was slowly rolled to 50° For the liquefied cargo, the stronger the fluidity was, the greater the impact on ship …
The Guide explains how nickel ore can continue to be safely shipped, whilst at the same time raising awareness of the seriousness of liquefaction. The Guide has been produced in response to several recent incidents where vessels and, tragically, the lives of seafarers have been lost as a result of liquefaction.
In addition to the discussions being held at IMO and the action taken by the International Group of P&I Clubs, the International Association of Dry Cargo Shipowners …
(b) a vessel is lost, and the loading of such a cargo is found to be the likely cause of that loss. B. The Cargoes (1) Nickel Ore Nickel ore is non-homogenous in form, unlike many mineral concentrates, and consists of both very fine clay-like particles and larger, rock-like pieces. There are two different types, limonite and
Nickel ore varies in colour. There are several types of ore of variable particle size and moisture content. Some may contain clay-like ores. For concentrates, see NICKEL CONCENTRATE.
These casualties have resulted in the loss of 66 seafarers' lives in just over 12 months. This guide aims to help masters, ship operators and other industry stakeholders understand the risks associated with the carriage of nickel ore cargoes. Unquote . Intercargo-Nickel-Ore-Guidance-Jan-2012.pdf
The document instructs the master to check cargo information and test samples if moisture levels appear high. It also lists loading, during voyage, and unloading check points to monitor cargo …
Strict compliance for overseas stockpiling and handling of Nickel Ore is monitored by AQIS. AQIS inspect the ore on arrival at Townsville and during unloading and loading into rail wagons …
It was noted that Limonite type of nickel ore contains less moisture and much easier to load than Silicate or Saprolite type of nickel ore. These circumstances could be attributed to the volume of the cargo reserve at the stockpiles of the …

The document provides guidelines for loading nickel ore cargo to prevent accidents caused by cargo liquefaction. It describes a past incident where a bulk carrier carrying nickel ore capsized due to liquefied cargo. It outlines procedures to check cargo moisture content and transportable moisture limit (TML) to ensure the cargo does not exceed TML. The document instructs the …
for nickel ore needs to be determined by a competent laboratory separately for every single cargo) and moisture ... commencement of loading. The ore is not found in a homogeneous form. Much of the material is very fine clay-like particles but there are also larger rock-like particles, some of which can be very large indeed.
Lateritic ore can undergo dramatic physical and chemical changes during months of leaching and rinsing, with weight loss of 15 to 25% and acid consumption of 150 to 500 kg per tonne of ore. For dynamic heaps, the spent ore is disposed of in a dump, often comingled with the plant residue.
It aims to help masters, ship operators and other industry stakeholders understand the risks associated with the carriage of nickel ore cargoes.
