The fungus Beauveria caledonica was highly tolerant to toxic metals and solubilized cadmium, copper, lead, and zinc minerals, converting them into oxalates. This fungus was found to overexcrete organic acids with strong metal chelating properties (oxalic and citric acids), suggesting that a ligand promoted mechanism was the main mechanism of mineral dissolution. Our data also suggested that

The gas chromatograph injector was held at 200 C and operated in split mode (35:1) with a column flow rate of 2 mL min −1. Separation was performed on a J&W GS Q PLOT column (30 m× mm). The gas chromatograph oven was held for 5 min at 35°C and then ramped at a rate of 10°C min −1 to 200°C, where it was held for 4 min. Mass spectra were acquired in the scan range 10–150 amu.

The formation of placer deposits is primarily due to sorting power of the transporting medium and the inherent physical properties of ore or other minerals. Heavier, stronger and stable minerals have better chances of accumulation and preservation as deposits whereas lighter and chemically unstable minerals get further disintegrated and dispersed.

Clay Minerals Properties, Occurrence and Uses Nova To a geologist, clay minerals are fine particles ( 2 µm in size) and are also major constituents of rocks, sediment and soils. To an engineer, ceramicist or mineralogist, clay minerals belong to the family of phyllosilicate (or sheet silicate) of minerals, which shows properties of plasticity, shrinkage, and hardening upon drying or firing.
