“…This process involves ion exchange between OH on the adsorbent surface and removed anions. Natural lime is often used for process and wastewater treatment [58][59][60][61][62][63][64][120][121][122][123][124][125][126]. Sulphate removal from water by adsorption has not always been successful -for example, in Darbi et al's research on sulphate removal from drinking and groundwater by bentonite [110].…”

“… 8,9 This occurrence is referred to as armoring, which stops the dissolution of limestone and significantly lessens the lifespan of a passive treatment system using limestone as its media. Thus, alternative media have been studied like dolomite (CaMg (CO 3 ) 2 ), magnesite (MgCO 3 ), marble (CaCO 3 ), serpentinite (Mg 24 Si 17 O 42.5 (OH) 31 ), 10 activated sludge, spent mushroom compost, 11 and concrete, 12 as treatment agent for AMD.…”

Goethite is a dominant component of nickel laterite ores, which is capable of adsorbing metal ions in water. The potential of the unused low-grade nickel ore (LGO) to treat synthetic acid mine drainage (AMD) was investigated.LGO characterization identified the presence of goethite (α-FeOOH), calcium oxide (CaO), and manganese aluminum oxide. The performance of LGO for AMD treatment was evaluated using jar test and compared with limestone. At 0.5 ml AMD/g media, LGO increased the pH of AMD to 5.36 while limestone completely neutralized it. LGO removed more than 99% of Al and Fe, 94% of Ni, and 93% of sulfates compared to a 70% sulfate removal using limestone. The lower sulfate removal may be due to the armouring of the limestone surface. Furthermore, a batch test was conducted using both LGO and limestone as layered treatment media in an oxic and anoxic setup. Effluent pH remained constant while conductivity and TDS stabilize at 2,000 μS/cm and 1,000 ppm, respectively. Both setups achieved 99% removal of Fe and Al,~90% Ni removal, and between 70% and 80% sulfate removal. These results indicate that LGO is a possible alternative material to be used for heavy metal adsorption for AMD treatment.

“…Limestone is a sedimentary rock with chemical formula CaCO 3 [3] and 4% of the earth crust contains carbonate mineral that consists limestone, chalk and biominerals [4]. Limestone also can be used as a neutralization agent in treating acidic water especially in treating AMD [5]. Other materials that can be used to treat AMD are organic material [6], carbide lime [7], hydrated lime [8], quicklime [9], etc.…”

In this study, low grade limestone (LGL) was used in treating acid mine drainage (AMD). Based on X-ray fluorescence (XRF) result, the content of calcium carbonate mineral in limestone used was around 80% that can be considered as LGL. The pH of AMD samples increased after treated with all parameter weights of LGL at every five minutes of interval times. The parameters weights of LGL used in the experiments were 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 g. For every parameter weight of LGL, the interval times used were 0, 5, 15, 20, 25 and 30 minutes. The highest of pH value obtained was 6.44 ± 0.00 by using 6.0 g of LGL at interval time 30 minutes. The suitable pH value chosen was 6.11 ± 0.00 by using 5.0 g of LGL at interval time 20 minutes because the parameter had complied with Standards A and B of Environmental Quality Act 1974 with less cost compared to other parameters. Heavy metals content such as arsenic, cadmium, chromium, iron, manganese and zinc had decreased after reaction with all LGL weights. The content of arsenic in AMD samples after reaction with all LGL weights had complied with both standards' requirement except with 1.0 g of LGL. The percentage of removal heavy metals by using all parameter weights of LGL such as arsenic, cadmium, chromium, iron, manganese and zinc were around 98.8 to 99.8%, 53.8 to 88.5%, 94.7 to 96.5%, 99.6 to 100%, 34.6 to 38.9% and 27.0 to 90.1%, respectively. AbstrakDalam kajian ini, batu kapur bergred rendah (LGL) telah digunakan dalam rawatan saliran lombong berasid (AMD). Berdasarkan keputusan pendaflour sinar-X (XRF), kandungan mineral kalsium karbonat di dalam batu kapur yang digunakan adalah sekitar 80% yang boleh dianggap sebagai LGL. pH sampel AMD telah bertambah selepas bertindakbalas dengan semua parameter berat LGL pada setiap lima minit selang masa. Parameter berat LGL yang digunakan dalam eksperimen adalah 1.0, 2.0, 3.0, 4.0, 5.0 dan 6.0 g. Untuk setiap parameter berat LGL, selang masa yang digunakan adalah 0, 5, 10, 15, 20, 25 dan 30 minit. Nilai pH yang paling tinggi diperolehi adalah 6.44 ± 0.00 dengan menggunakan 6.0 g LGL pada selang masa 30 minit. Nilai pH yang paling sesuai telah dipilih adalah 6.11 ± 0.00 dengan menggunakan 5.0 g LGL pada selang masa 20 minit kerana parameter ini adalah kurang kos untuk mematuhi Piawai A dan B berbanding parameter yang lain. Kandungan logam berat seperti arsenik, kadmium, kromium, besi, mangan dan zink telah berkurangan selepas bertindakbalas dengan semua berat LGL. Kandungan arsenik dalam sampel-sampel AMD selepas bertindakbalas dengan semua berat LGL telah dipatuhi dengan kehendak kedua-dua standard kecuali dengan menggunakan 1.0 g LGL. Peratusan penyingkiran logam berat dengan menggunakan semua parameter berat LGL seperti arsenik, kadmium, besi, mangan dan zink masing-masing adalah sekitar 98.8 hingga 99.8%, 53.8 hingga 88.5%, 94.7 hingga 96.5%, 99.6 hingga 100%, 34.6 hingga 38.9% and 27.0 hingga 90.1%.
