The cleaning regime to then be used in preparing for the next cargo will depend on a number of factors: a) The nature of the previous cargo The previous cargo may be incompatible with the next cargo and which will necessitate particular care when cleaning the holds. Manganese ore, for example, is rendered worthless by
Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles.
The different ores have different cleaning purposes. For open-pit mining of bauxite, it is necessary to wash away the clay mud adhered to the surface of the ore; in the open-pit mining of nickel laterite, the gravel in the fine ore should be washed and removed. Ore Washing is generally carried out in two stages to meet the process requirements.

Approximately 80% of the hydrometallurgical process of low-grade laterite nickel ore is converted into residue. The handling of residues from processing is a significant challenge in this process According to the characterization test, each type of extraction process produces a different type of residue.
Nickel ore washing machine for sale in Philippines. July.29,2021. Laterite nickel ore washing equipment is an equipment that uses hydraulic or mechanical force to scrub the ore that is cemented by clay or contains more mud, so that the ore is broken up, and the fine mud on the surface of the ore is washed and separated. ...
Examples occur in alumina, nickel laterites, uranium and occasionally gold. The over-riding principle in ore washing is to provide sufficient energy and time to detach the fine …
It is said that it is necessary to use crushing equipment to extract nickel from its ore. The extraction of nickel process generally consists of crushing, sieving, washing, re …
Liquefaction risks of nickel ore cargoes from Indonesia and the Philippines have been a long-standing prominent issue which require constant vigilance and review by shipowners and charterers. Since 2010, the …
A kind of leaching residue generated during high pressure acid leaching of laterite nickel ore is creatively prepared as blast furnace charge for ironmaking. Results show that the briquettes with uniform shape, compressive strength higher than 72.3 N/pellet, and cracking temperature over 400 °C can be obtained by the non-binder briquetting with water content of …
The demand for nickel has been steadily increasing in the 21st century, primarily driven by the rising demand for electric vehicle batteries. Nickel in laterite is associated within silicate in saprolite ore and hydroxide/oxide in limonite ore. Recently, the sulfation–roasting–leaching process has been developed to address the challenges of …
Nickel consists of two types of common ores, sulfides and laterite ores. Laterite nickel ore, which comprises 73% of the world's proven nickel reserves is the dominant source of nickel. However, only 42% of the world's production of nickel comes …
The acid dissolves inorganic foulants such as calcium carbonate, magnesium and sodium salts, fine ore Minerals such as silica, and fine iron particles. The carbon acid wash cycle takes about 4.30 hours. Acid washing may also help in removing some of the base metals such as copper, zinc, & nickel loaded on carbon.
The amounts of metal elements (iron, magnesium, aluminum, chromium, nickel, cobalt, and manganese) within the limonitic laterite ore were determined after total digestion with a mixture of acids, including hydrofluoric acid (HF), hydrochloric acid (HCl), nitric acid (HNO 3), and perchloric acid (HClO 4). The results are provided in Table 1.
The energy costs required to refine metal values contained in ore to concentrates constitute the majority of the cost to produce metals. On average across the mining industry, 44% of the total electricity consumption is dedicated to crushing and milling activities (Fig. 1).Size reduction operations, nearly 150 × 10 9 kW h, are the largest single consumer of energy …
The global interest in utilizing nickel for electric vehicle (EV) batteries has garnered significant attention. In the form of NiSO4·6H2O crystals, nickel is a crucial raw material for fabricating battery cathodes in EVs. These crystals are commonly derived from the hydrometallurgical method. This study investigated the pH effect on the precipitation method to …

Nickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal with a relatively high melting point and excellent corrosion resistance. Nickel is commonly found in the Earth's crust, but it is typically extracted from its ore minerals through …
High-pressure acid leaching (HPAL) is an excellent hydrometallurgical process for recovering nickel and cobalt from laterite ores due to its fast kinetics, stability of residues …
The composition of low-grade laterite ore from Yuanjiang, Yunnan, China was tested by chemical analysis. Under 7% of CaF 2 for the adjuvant agent and 8% of anthracite for the reducing agent, the main metal nickel and iron in laterite ore (100 g) can be efficiently recovered after high temperature (1250 °C) reduction. The process is shown in Fig. 1.
Samples from leachate, wash solution and filter cake analyzed for Ni using atomic absorption spectrophotometer (AAS).

The results show that the nickel laterite deposited in Southeast Sulawesi Island, Indonesia, belongs to the typical high-nickel and low-iron garnierite-type laterite.
Preparation of a cargo hold is not just a question of sweeping, cleaning or washing down the hold. There are a number of matters to consider, and failing to adhere to good practice can result in substantial claims. A lack of knowledge, often originating in chartering or commercial departments, can also be the underlying cause of major claims.
