Groundwater Exploration in Hard Rock Areas of Vizianagaram District, Andhra Pradesh, India
Identifying a good site for groundwater exploration in hard rock terrain is a challenging task. In hard rocks, groundwater occurs in secondary porosity developed due to weathering, fracturing, faulting, etc., which is highly variable and varies sharply within very short distances, contributing to near-surface inhomogeneity. In such situations topographic, hydrogeological and geomorphological fe...
متن کاملMineralogy, geochemistry and genesis of Temelieh Manganese ore Deposit (NorthWest of Selseleh, Lorestan Province)
Temelieh area is located about 20 Km northwest of Selseleh (Lorestan Province). Geologically, the area is a small part of the Harsin radiolarite complex. Petrography consists of radiolarite, peridotite, gabbro, plate dikes, basalt and andesite, limestone, and marble. Manganese mineralization occurs as vein-veinlet and is mainly formed in faults, joints, and fractures that crosscut in radiolarit...
متن کاملFungal Leaching of Manganese Ore
Bioleaching is technologically feasible for extraction of manganese from low grade ores (containing manganese less than 35% by weight). The principle involves the non-enzymatic reduction of pyrolusite [Mn(IV) oxides] to +2 oxidation state by fungi with the production of metabolites such as oxalic acid and citric acid. In the present investigation, a fungal strain, Penicillium citrinum was isola...
متن کاملMineralogy and geochemistry of the Hajiabad manganese deposit, Hormozgan province
The Hajiabad manganese deposit is located about 40 km northeast of Hajiabad, Hormozgan Province. This deposit is structurally located in the southeastern border of the Sanandaj-Sirjan zone. The manganese mineralization in the study area is hosted by calcite-dolomitic marbles and mica schists of Devonian age, as layers, veins and massive ores. Based on microscopic investigations, the ores are do...
متن کاملThe Smelting of Manganese Carbonate Ore
The practice of manganese ferroalloy smelting has traditionally been based on utilising oxide ores which typically contain a high level of manganese. This preference for oxides has even been extended to the modification of natural carbonates into nodulized oxides. However smelting practices developed over the past 30 years have created a market for natural manganese carbonate ores, driven in pa...
