The nickel is predominantly mineralised as pentlandite in a disseminated texture in an ultramafic ore. The elemental assay of the samples is shown in Table 1. It indicates the sample contained …

Tailings are typically pumped by pipeline as a (slightly) thickened slurry. A typical tailings slurry will be deposited at between 25% to 45% solids by mass. To achieve high % …

Table 1 shows as a major example the summary of the metal contents of various tailings from some of the existing and historic metal mines in Finland. The tailings contain for example nickel, cobalt and zinc. The value of the metals in one single tailings waste pile reaches hundreds of millions of euros calculated from the concentrations and ...

The experimental results show that the addition of nickel tailings can significantly enhance the performance of the composite electrothermal coatings. Using …

In this study, an orthogonal test table (L 18 (3 7)) was established for a Ni tailings pond in Yunnan Province, China, to determine the arrangement of five factors (initial pH, chloride concentration, temperature, tailing particle size, and solid-liquid ratio) when preparing leaching agents. A GAM was used to fit the factors, the metal ...

26 May, 2021. In the post-COVID-19 global economic recovery, unprecedented stimulus plans by governments look to accelerate the emerging "Green Economy". This approach will ultimately pivot on the metals used to make batteries, and specifically lithium-ion batteries – the current and next generation battery chemistry of choice.
