·The concentrate used in this experiment originated from the flotation of low grade nickel sulfide ore provided by Jinchuan Group China It was crushed ground and sieved into powder sample with a particle size of 88 178 μm
·In 2022 Canada produced 143 266 tonnes of nickel in concentrate which is 10% less than the previous year Ontario produced 50% of Canada s mined nickel and Quebec produced 27% with the rest from Newfoundland and Labrador and Manitoba Nickel monthly average nominal US$ per tonne prices 2013 2022 World Bank Commodity Price Data
·China is the world s largest nickel consumer but China s local nickel ore resources are scarce and nickel ore is highly dependent on imports With the recovery of China s stainless steel industry and the rapid development of new energy sector the demand for nickel from downstream industries is expanding and CRI expects that China will still import a large
The production of ferronickel concentrate from low grade nickel laterite ore containing % nickel Ni was studied by the non melting reduction magnetic separation process The sodium chloride was used as additive and coal as a reductant The effects of roasting temperature roasting duration reductant dosage additive dosage and grinding time on the grade and
On average TNML produces approximately 400 000 tonnes of ore and 5 500 tonnes of nickel in concentrate per annum respectively Trojan Mine located in Bindura was restarted in 2012 after 4 years of care and maintenance It has an inferred resource size of million tonnes of % nickel ore grade which amounts to 85 600 tonnes of contained
·The samples of nickel ore and nickel concentrate were collected from the Hongqiling nickel deposit in Jilin province The raw materials were crushed and passed through a mm sieve The rough samples were then ground for 48 hr in a high alumina ball mill to a final size of < mm Homogeneity of the samples was tested by X ray
In hydrometallurgical processes nickel sulfide ores undergo flotation differential flotation if Ni/Fe ratio is too low and then smelted After producing the nickel matte further processing is done via the Sherritt Gordon process First copper is removed by adding hydrogen sulfide leaving a concentrate of only cobalt and nickel Then
·X ray diffraction analysis revealed that pentlandite and chalcopyrite were the prominent mineral phases in a South African sulfidic nickel ore concentrate that hosted nickel and copper Cobalt was found to be closely associated with the nickel bearing pentlandite phase of
·Laterite nickel ore with a high MgO and SiO 2 impurity content caused by the removal of a considerable amount of iron through weathering was used for the experiment Petrus et al 2019 Sun et al 2021 Forster et al 2021 In previous studies nickel was found to be mainly present in the form of metal oxides and silicates in laterite
·Nickel is one of the metals that are significant in several applications including construction petrochemicals automobiles fabrication and welding transportation electronics water sector as well as in low carbon technologies Elshkaki and Graedel 2013; Habib 2020 Its demand has been increasing in the last few decades with annual production growth rate of
