A study of the electroleaching of manganese ore[12-21-2007]
Electrochemical processing has been adopted to upgrade the Egyptian low-grade manganese ores. In order to establish the contribution of the different mineral species to the electrochemical behavior of the ore in sulphuric acid solutions, cyclic voltammetric studies were c......
China Imported 30% more Manganese Ore in Q1 of 2008[4-30-2008]
According to statistics by China Customs, import volume and £¦#118alue of manganese increased sharply in the first quarter of 2008. Gross import volume was 1,793,577 tonnes up by 30% from 1,375,873 tonnes of first quarter of 2007. Soaring manganese ore price makes import £¦#118alue......
Aquila looks for iron ore and finds manganese[4-30-2008]
Aquila said the Tex Report, an industry publication, reported earlier this month that contract prices for high-grade manganese ore ranged from $11 (R86) to $15 a ton, while spot prices were quoted at $17 a ton."It is reported that manganese prices are expected to firm due to a sh......
Percolation Leaching of Manganese Ore by Aqueous Sulfur Dioxide[4-17-2009]
The sulfite leaching of an Italian Mn ore has been carried out to determine the feasibility of extracting Mn by percolation leaching. Aqueous SO sub 2 has been found to be an effective leachant for Mn dissolution owing to fast dissolution kinetics and low temperatures. Bench-scal......
Neurobehavioral functions among workers exposed to manganese ore[4-17-2009]
The Neurobehavioral Core Test Battery of the World Health Organization was performed on 17 baggers (mean age 36.6 years) in a manganese ore milling plant and 17 referents (mean age 35.7 years). The baggers had a mean exposure period of 7.4 (range 1-14) years with a mean blood man......
