RECYCLING OF NICKEL SLAG TAILINGS INTO LIQUID PRODUCTS A CASE STUDY In addition the wind blows slag tailing fines into areas adjacent to the tailings causing even more environmental damage the old nickel slag tailings at SUNP contain numerous glassy non magnetic phases with nickel chromium iron etc [1] Table 1 lists the
Nickel could be mined from sulfide or laterites ores Thereabout 40% of reserves is sulfides ores derived from volcanic or hydrothermal process and 60% is laterites ores formed near the
Heavy metal elements concentration study has been determined from soils and tailing sediments in laterite nickel post mining area in Motui District Southeast Sulawesi
Nickel extraction by bioleaching from laterite ores and MTs has reached 8 26% with aerobic conditions and microwave pretreatment enhancing nickel yields Up to % nickel recovery from low grade sulfide tailings and 53 57% extraction in just 7 days have been attained via novel bioleaching techniques [129]
Since tailings deposition ended at the decommissioned Nickel Rim Ni Cu mine near Sudbury Ontario Fig 1 the water table has fallen from the tailings surface to about 1 m below the diffusion of gas phase O 2 into the unsaturated zone has caused the oxidation of sulfide minerals in the shallow tailings Sulfide oxidation is indicated by the
tantalum tailings are shown on Table 1 The nickel tailings tended to be finer grained average 75% fines than both iron 67% fines and gold 58% fines Tailings from a tantalum mining operation were comparatively sandy with only 38% fines Table 1 % Fines test results by commodity Gold % fines Nickel % fines Iron % fines
Nickel content mg kg in native dominant plants in mine tailing sites Nickel content mg kg 1 in native dominant plants in mine tailing sites is shown in Table 2 The highest mean nickel content M = SD = is found in sampling site 3 where carabao grasses are found Rice straws in sampling site 2 M = SD =
Bioleaching of copper nickel and cobalt from the low grade sulfidic tailing of Golgohar Iron Mine Iran Ali Ahmadia d ⁎ MaryamKhezrib Ali Akbar Abdollahzadehb MasoodAskaric a Department of Mining Engineering Isfahan University of Technology Isfahan 84156 83111 Iran b Department of Mining Engineering University of Kashan Kashan Iran c Golgohar Iron Ore and Steel
The lateritic nickel ore in this work was from Sulawesi Island Indonesia The chemical composition of limonite and saprolite ore in this work is listed in Table 1 Limonite has lower nickel content than saprolite Nevertheless its iron content is higher The binary basicity MgO/SiO 2 of limonite and saprolite is and respectively
This study investigates the influence of salinity on the bioleaching efficiency of a copper‑nickel‑cobalt bearing sulphidic tailing obtained from Golgohar iron ore desulphurization plant
Characterizing the unique microbiomes associated with tailing environments is key to identifying consortia that may be used as the foundation for innovative mine waste bioremediation strategies At Nickel Rim North NR locations NR18 and NR3 were selected for comparison although NR3 has shallow water table elevation and the shallow
