·Forests once deforested through mining losses its rich biodiversity The re opening of open pit mining corporation in 2011 in the small village of Bato Bato Narra Palawan had caused deforestation floods and low rice harvest This study determined the nickel content in topsoil and native dominant plants in mine tailings Field data collection and laboratory
·Nickel Platinum Group Elements Bauxite Uranium Chromium Molybdenum Tin Vanadium Manganese Niobium Rare Earths Lithium Waste rock 72 000 000 000 tonnes Ore milled 18 800 000 000 tonnes Ore produced 10 180 000 000 tonnes Tailings 8 850 000 000 tonnes Figure 3 Estimate of the volume of tailings and waste rock produced in 2016 in
For example the Caren tailing impoundment in central Chile was retained by an earth fill dam with a maximum height of 108 m James et al 2011 the Bahuerachi tailing dam in Mexico was designed with a maximum height of 100 m with the capacity of 200 million m 3 tailings and the Yuhezhai iron tailing dam in Yunnan China was designed to a
·Therefore mechanical grinding and steam curing at an early age are applied to promote the reaction activity of the recycled ferronickel slag tailing in this study Compared with standard curing the compressive strength of hardened FNS cement paste with steam curing at 60 °C or 80 °C increased by % or % and the connected porosity
·Pemanfaatan tailing ini bertujuan untuk menambah nilai ekonomi dari tailing tersebut serta sebagaisalah satu solusi untuk mengurangi dampak pencemaran lingkungan yang diakibatkan oleh limbah
Coral Bay Nickel Corporation CBNC produces mixed sulfide MS as an intermediate raw material for nickel and cobalt products at Palawan Island in the Philippines The company is engaged in the rehabilitation of tailings dams which are facilities for accumulating the neutralized and stabilized unneeded mineral solids resulting from mineral processing the process of
·The results showed that leaching of about 99% of nickel content of the washed tailing could be achieved using mol sulfuric acid pulp density of 1/20 gmL −1 and particle size of −180 250 mm at 80 °C after 240 min Kinetic analysis of the leaching data properly followed the shrinking core model and the dissolution rate of nickel was
·The composition of PLS and recoveries for the main elements have been shown in Table 1 The low recovery of cobalt 2 3% could be due to the low grade of cobalt in the tailing sample These results show that heap leaching could be a good candidate for the nickel extraction from the flotation tailing In order to study the nickel
·From Table 4 it is quite clear that a higher amount of Cr is required in the metal; hence a ratio of Cr tailing to sub grade manganese ore in the mixture must be > 1 For the same reason for all the FactStage study purposes 100 g of Cr tailing was kept constant while varying other components sub grade manganese ore coke and lime
The results showed that leaching of about 99% of nickel content of the washed tailing could be achieved using mol sulfuric acid pulp density of 1/20 gmL−1 and particle size of −180 250 mm at 80 °C after 240 min Kinetic analysis of the leaching data properly followed the shrinking core model and the dissolution rate of nickel was

·Nickel mine tailing contains other rare earth elements and pollutants and the local tropical rainforest climate receives frequent rainfall causing pollution outflows to seep into groundwater or the ocean Local factories have also been exposed for numerous discharge violations in the disposal of nickel ore waste Table of Contents Prev
·Tailings are residual material streams generated in mining activities Regarding sulfide ore mines tailings are typically produced in froth flotation process where valuable sulfide minerals are selectively separated from non valuable gangue Fuerstenau et al 2007 After the separation gangue minerals are disposed in tailing ponds Lottermosser 2010
·Tailing in context to mining is defined as the waste or non economic by product generated during mining activities processing of minerals and other materials that contain small amounts of residual valuable minerals chemicals water and heavy metals Adiansyah et al 2015 Studies indicated that the process of mineral exploitation and
·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
