·Leaching behavior of mine tailing sample and froth concentrate was compared under high pressure leaching using the determined conditions 3 Flotation behavior of copper and nickel from mine tailing was investigated under varying concentrations of PAX ranging from 0 g/t to 200 g/t when other flotation parameters were fixed at 200 g/t of
·Nickel was quickly recovered from tailings 20 ppm/h than from ore ppm/h with biological and acidic methods It therefore appears that optimum nickel mobilization with B subtilis will occur in the active phase Biological method has environmental advantage and thus appropriate for tailing dumps management
Nikel merupakan logam yang sangat penting di Indonesia Indonesia salah satu penghasil nikel terbesar di dunia Nikel yang banyak terdapat di Indonesia merupakan nikel laterit Pengolahan nikel laterit dapat menggunakan metodehidrometalurgi dan pirometalurgi Semakin banyak pengolahan bijih nikel makasemakin banyak pula tailing atai limbah dari bijih nikel yang
TAILINGS "Consider a picture such as Nickel Tailings #34 from Burtynsky s "Mines and Tailings " a series devoted to the environmental aftermath of metal mining and a cool grey sky against a wintry violet backdrop of distant trees a brilliant orange river swerves toward the camera from within a deep brown landscape
·The XRF was performed to analyze the iron and nickel content in concentrate and tailing while XRD and SEM EDS were used to identify the phase transformation and microstructure of reduced ore The result showed a high MgO/SiO 2 ratio in saprolite generates the iron nickel magnesium silicate which was difficult to reduce rather than the iron
·Nickel reserves are 70 % from laterite ores and nickel production are 40 % from these reserves It occurs due to the fact that laterites ores require more complex processing than sulfides
·This study determined the Cobalt content in topsoil in mine tailing sites within the rice farms Field data collection and laboratory analysis methods were used in this study The Cobalt content in topsoil in three sampling sites is high from mg/kg to mg/kg in comparison with the average Cobalt content a topsoil should contain
·The results showed the higher concentration of heavy metals from different sampling points top middle and bottom of the tailing dump which were dominating in various fractions such as Fe Pb
·Study on mechanically activated ferrous extraction tailing of nickel slag as cementitious materials Physical and chemical properties mechanical properties and reaction mechanism The pouring sample size of FETNS mixed paste is 40 mm 40 mm 40 mm each sample is composed of three cement paste cubes After 24 hours the samples were

·Modified nickel cobalt tailing activated PMS for highly efficient degradation of organic pollutants Multiple scale effect and active sites article{Xiang2024ModifiedNT title={Modified nickel cobalt tailing activated PMS for highly efficient degradation of organic pollutants Multiple scale effect and active sites} author={Yuwei Xiang and
·Pemanfaatan tailing ini bertujuan untuk menambah nilai ekonomi dari tailing tersebut serta sebagaisalah satu solusi untuk mengurangi dampak pencemaran lingkungan yang diakibatkan oleh limbah
·This study presents the exploratory results on the nickel extraction from a serpentine flotation tailing sample containing sulfide and serpentine minerals at wt % of nickel
·A low grade nickel‑cobalt‑copper bearing sulphidic tailing was used in all of the experiments It was obtained from the desulphurization plant of Golgohar Iron mine Sirjan Iran from reverse flotation The characteristics of the representative sample were presented in detail in a previous publication Ahmadi et al 2015
·Study area and tailing sampling The study area Fig S1 was a tailing pond in Yuanjiang N Yuxi City Yunnan Province
·Specific gravity of unpulverized iron ore tailing sample is which is slightly higher than the specific gravity of conventional fill material lead chromium cadmium copper nickel and zinc are within the prescribed limits and hence found to be non hazardous It is important to note that ingress of water through reinforced fill is
·This study investigated metals of tailings from Tonglvshan mine in Daye and assessed the effect of metal contamination in water and sediment near the tailing reservoir The concentration of copper lead zinc cadmium chromium and nickel was measured in deposit samples taken from a profile in an abandoned flotation tailing reservoir as well as in water and
·occurrence states of Ni and Co are relatively dispersed For the limonite in laterite nickel mine the nickel bearing magnetite concentrate with nickel grade of % and recovery rate of % can be obtained by reduction roasting magnetic separation process For the serpentine in laterite nickel mine the cobalt bearing concentrate with Co
·In gas chromatography GC the sample is vaporized and injected onto the head of a chromatographic column Elution is brought about by the flow of an inert gaseous mobile phase such as helium argon nitrogen carbon dioxide and hydrogen In GC the mobile phase does not interact with molecules of the analyte and it only transports the analyte through 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 The general element mobility trend showed that Mn and Co are positively correlated in soil sampling from all layers and tailing samples whereas Fe and Cr show a negative
·nickel due to two of the ten samples being from a lateritic nickel tailings that have particularly low density due to the intense nickel extraction process The average laboratory air drying density of the other eight nickel samples is t/m 3 which agrees fairly well with the reconciled dry density for nickel
