“…The very low recovery of pyrite in the oxalate extraction is in good agreement with observations by Bhattacharya et al, 36 Birkefeld et al, 37 Belzile et al, 38 Willet et al, 39 and Dold 35 who reported that pyrite and Cu-sulfides do not dissolve in oxalate extracts.…”

Jarosites and schwertmannite can be formed in the unsaturated oxidation zone of sulfide-containing mine waste rock and tailings together with ferrihydrite and goethite. They are also widely found in process wastes from electrometallurgical smelting and metal bioleaching and within drained coastal lowland soils (acid-sulfate soils). These secondary minerals can temporarily store acidity and metals or remove and immobilize contaminants through adsorption, coprecipitation, or structural incorporation, but release both acidity and toxic metals at pH above about 4. Therefore, they have significant relevance to environmental mineralogy through their role in controlling pollutant concentrations and dynamics in contaminated aqueous environments. Most importantly, they have widely different acid release rates at different pHs and strongly affect drainage water acidity dynamics. A procedure for estimation of the amounts of these different forms of nonsulfide stored acidity in mining wastes is required in order to predict acid release rates at any pH. A four-step extraction procedure to quantify jarosite and schwertmannite separately with various soluble sulfate salts has been developed and validated. Corrections to acid potentials and estimation of acid release rates can be reliably based on this method.

“…Kim et al (2010) who postulated that higher Zn solubility in the rhizosphere was caused by the marked increase in dissolved organic carbon, exuded from roots, compared to the bulk soil. Likewise, Birkefeld et al (2006) suggested that dissolution of metal-containing minerals and slag particles in forest soils was accelerated as a result of an increase in dissolved organic carbon concentration.…”

Plant growth-promoting rhizobacteria (PGPR) are soil bacteria that are able to colonize rhizosphere and to enhance plant growth by means of a wide variety of mechanisms. In the present study M. yunnanensis and S. chelatiphaga strains were recognized as new records in Iran flora. According to results these strains significantly affected plants zinc and phosphorous contents which could be due to production of phyto-siderophore. Siderophore producing bacteria

“…The negative impact of tin mining activities on the environment is mainly due to the excavation of large amounts of sand and the eventual accumulation of a large volume of tailings (Banat et al, 2005;Remon et al, 2005;Akinlua et al, 2006;Birkefeld et al, 2006;Nyarko et al, 2006), which significantly alter the natural constituents of radionuclides in the soil and thus affect the terrestrial ecosystem. It has been observed that mining, milling and processing of uranium-and thorium-bearing minerals lead to enhanced radiation exposures not only to the workers but also to the inhabitants of the mining and processing sites (UNSCEAR, 2000;Lipsztein et al, 2001).…”
