“…Low pH and high SO 4 2− concentrations occur where the pyrite oxidation is pronounced that favors the calcite (CaCO 3 ) and dolomite (CaMg(CO 3 ) 2 ) dissolution from the rocks, increasing the concentrations of Ca and Mg in areas downstream the effluent discharge (Shim et al 2015). On the other hand, limestone and dolomite have been used for neutralizing the AMD and precipitating metals (Genty et al 2012).…”

“…The Al concentrations decreased at P1 and P8 (dry month) and P1 and P2 (wet month), probably due to the pH increase, resulting in significant Al precipitation. Other metals and elements can be removed by adsorption/coprecipitation with Fe and Al precipitates (Shim et al 2015). In addition to the increase in total iron and sulfate with the sample's acidification, in the dry period, the pH rises with the bicarbonate concentration in the groundwater samples (Fig.…”

“…Caraballo et al (2016) proposed three hydrochemical stages for AMD in a sulfide mining district: a high metal concentration with a low flow rate; an extreme metal concentration with a high flow rate; a mixed situation comprising a high flow rate, and medium high metal concentration. In addition to seasonal variations, important processes controlling the spatial distribution and concentration of elements in streams affected by AMD are dilution by mixing, co-precipitation/adsorption, redox processes, and pH fluctuations (Shim et al 2015). In aquifers, the AMD extension can be controlled by advection through the fractures, diffusion-controlled transport into the porous matrix, diffusion from the matrix into the fractures, pH buffering by carbonate, and silicate minerals as well as loss of sulfate and iron due to gypsum and ferrihydrite precipitation (Molson et al 2012).…”

Effects of acid mine drainage (AMD) were investigated in surface waters (Laranjinha River and Ribeirão das Pedras stream) and groundwaters from a coal mining area sampled in two different seasons at Figueira city, Paraná State, Brazil. The spatial data distribution indicated that the acid effluents favor the chemical elements leaching and transport from the tailings pile into the superficial water bodies or aquifers, modifying their quality. The acid groundwaters in both sampling periods (dry: pH 2.94-6.04; rainy: pH 3.25-6.63) were probably due to the AMD generation and infiltration, after the oxidation of sulfide minerals. Such acid effluents cause an increase of the solubilization rate of metals, mainly iron and aluminum, contributing to both groundwater and surface water contamination. Sulfate in high levels is a result of waters' pollution due to AMD. In some cases, high sulfate and low iron contents, associated with less acidic pH values, could indicate that AMD, previously generated, is nowadays being neutralized. The chemistry of the waters affected by AMD is controlled by the pH, sulfide minerals' oxidation, oxygen, iron content, and microbial activity. It is also influenced by seasonal variations that allow the occurrence of dissolution processes and the concentration of some chemical elements. Under the perspective of the waters' quality evaluation, the parameters such as conductivity, dissolved sodium, and sulfate concentrations acted as AMD indicators of groundwaters and surface waters affected by acid effluents.

ÖZÇalışmada Menteş havzası içinde yeralan demir yataklarının yeraltısularına etkisi araştırılmıştır. Seyhan nehri ana havzasında yer alan Menteş havzasında yıllık ortalama yağış 460 mm, havza alanı ise yaklaşık 43 km 2 dir. Çalışma alanında tanımlanmış başlıca birimler Prekambriyen yaşlı metakırıntılılar, Alt Kambriyen yaşlı kuvarsitler, Orta Kambriyen yaşlı rekristalize kireçtaşları, Ordovisyen yaşlı metakırıntılılar, Miyosen konglomeralar ve güncel alüvyonlardan oluşmaktadır. Rekristalize kireçtaşı ve dolomitler çalışma alanındaki ana akiferler olarak belirlenmiştir. Seçilen 15 adet su noktasında yağışlı ve kurak dönemde su örnekleri alınarak anyon, katyon ve iz elementler açısından içerikleri belirlenmiştir. Suların sıcaklık (T), pH, EC değerleri yerinde ölçülmüştür. Her iki dönem için suların sıcaklık değerlerinin 7 -19 o C arasında, pH değerlerinin 7,26 -8,7 arasında ve EC değerlerinin 47,3 μS/cm -642 μS/cm arasında değiştiği ortaya konmuştur. Piper diyagramında karbonat sertliği %50'den fazla olan Ca oranı yüksek Ca-Mg-Na+K-HCO 3 tipi sular sınıfında yer aldığı ortaya çıkan sular, rCa> rMg > rNa > rK ve rHCO3> rSO 4 > rCl şeklinde bir katyon-anyon trendi sergilemiş olup, bu dağılım, kireçtaşı-dolomit gibi karbonatlı akiferlerden gelen suları temsil etmektedir. Oksijen-18 (δ 18 O) (‰-10,93 -‰-8,27) ve Döteryum (δ 2 H) (‰-64,18 -‰-54,58) değerleri suların meteorik kökenli olduğunu göstermektedir. Örneklerin ana anyon, ana katyon ve yerinde ölçülen T, pH, EC değerleri içme suyu standartlarında (TS266 ve WHO) verilen limit değerlerin altında kalmıştır. İz element analizleri kapsamında 66 parametre ICP-MS yöntemiyle incelenmiş olup, Hg, Cd, Th ve Ag gibi toksik etkisi yüksek elementlerin de içinde olduğu 30 dan fazla element dedeksiyon limitleri altında kalmıştır. As, B, Co, Cr, Cu, Mo, Ni, Pb, Sb, Ti, U, V, W, Zn, Se ve diğer elementlerin değerleri ise içme suyu standartlarına (TS266 ve WHO) göre ihmal edilebilecek kadar düşüktür. Elde edilen tüm sonuçlar göstermiştir ki, Menteş havzasında yer alan demir maden sahaları ve yakın çevresindeki yeraltısuları, incelenen inorganik parametreler açısından TS266 içme suyu standartlarına uygundur.

Acid mine drainage (AMD) waters are one of the most important ecological risks at the global level because of its high heavy metals content and strong acidity. Treatment of AMD water is a complex and expensive. One of the most widely used treatment process is the neutralization process of AMD. The result of neutralization is the production of sludge which may contain various other (heavy) metals, depending on the chemical characteristics of the mine water treated. In this paper, leachability and toxicity of the sludges obtained during the neutralization process of wastewater from Saraka and Robule acid mine drainage and the sludges after the stabilization process at different temperatures is tested. Sludge produced in the neutralization process of Robule AMD R4 (40)
