Fungal 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 کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
The 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...
متن کاملMechanical Properties of Low Plasticity Clay Soil Stabilized with Iron Ore Mine Tailing and Portland Cement
Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and diffe...
متن کاملBeneflciation Studies of Bama Oxidized Lead and Zinc Ore
Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main objective of the present investigation was the up-grading of the ore from Goshfil which is the major deposit in Bama. The ore contained about 16% zinc as smithsonite, about 1...
