Nickel and nickel-containing materials play an important role in the technologies and applications that are helping achieve key environmental policy objectives, such as reducing carbon emissions. Even though nickel is an essential element for plants, as with all metals and chemicals, excessive amounts can adversely impact the quality of the ...

Today it's announcing up to $10 million in funding to explore ways to use plants for extracting nickel from American soils. They're calling the exploratory topic "Plant HYperaccumulators TO MIne Nickel-Enriched Soils," or PHYTOMINES, encouraging partnerships between scientists, farmers, and the battery and mining industries.

Life cycle assessment is a valuable tool that is used to conduct the environmental impact assessment of different metal extraction processes. Life cycle assessment assesses impacts on the environment, human health, land, water, and soil during mining and other similar processes, as visible in some previous studies (Mahmud, Huda, Farjana, & Lang, 2018a, 2018b).

The extraction of nickel-rich ores often requires large-scale mining operations that can result in the destruction of wildlife habitats, deforestation, and the fragmentation of ecosystems. The loss of habitats can have serious …

The long-term supply of nickel to society was assessed with the WORLD7 model for the global nickel cycle, using new estimates of nickel reserves and resources, indicating that the best estimate of the ultimately …

Each tonne CO 2 sequestered can be used to recover 98.7 kg nickel and 2.7 kg cobalt with over 90% nickel and cobalt recovery and around 60% CO 2 mineralization efficiency. The process utilizes the strong competition between carbonate precipitation and complexation formation during the simultaneous metal extraction and enhanced CO 2 mineralization.

Laterite ore is a valuable resource due to its high content of metals essential for modern technology, including nickel, iron, and cobalt. However, extracting nickel from laterite ores is challenging due to their complex mineral composition and low nickel concentrations. This study examined the leaching behavior of pre-roasted laterite ore and the effect of roasting on …

Altilium Group today announced an agreement with PT Indo Mineral Research, a member of the Sebuku Group, one of Indonesia's largest mining groups, to co-operate in the development and promotion of the DNi …

Rare earths mining and processing in China, the extraction and refining of laterite nickel in Indonesia, and cobalt mining in the Congo, are three good examples of the disconnect between the ...

Nickel extraction from primary resources such as ores/minerals (sulfides, arsenides, silicates, and oxides) including the unconventional one viz., the polymetallic sea nodules, and …

Today, there are two major methods of nickel mining: ... Hard rock mining, or extracting lithium from mineral ores (primarily spodumene) found in pegmatite deposits. Australia, the world's ...

Unlike iron mining, extracting nickel ores, which also contain copper, cobalt and platinum, produces acid byproducts. This sulfide mining has a toxic legacy across the world, including mines owned ...

Rare and valuable plants that naturally "mine" large quantities of nickel are thought to be hiding in Indonesia's forests – but it is a race to discover them before they are wiped out.

Despite gold's price slump, strong copper and iron ore prices lifted MINING's ranking of the world's 50 most valuable miners to a new record high of $1.35 trillion.

Nickel is an important strategic metal produced at over 2 million tonnes annually [1].Approximately 60% of all Ni is consumed in the production of stainless steel [2, 3].Currently, Ni is primarily extracted from two types of ores: laterites and sulfides [[4], [5], [6], [7]].Although sulfide ores account for a smaller fraction of global Ni reserves, approximately 60% of global Ni …

The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde
