Mineralogical Properties

Muscovite mica formed as a primary mineral in pegmatites and granodiorite differs in physical properties compared to muscovite mica formed by secondary alteration (mica schist) (Table 2). The main differences are in flexibiUty and abiUty to be delaminated. Primary muscovite is not as brittle and delaminates much easier than muscovite formed as a secondary mineral. Mineralogical properties of the principal natural micas are shown in Table 3. The make-up of muscovite, phlogopite, and biotite are as follows ... 

On the basis of this comparison study, at present, it is still difficult to adopt a universal selective sequential dissolution procedure, which may be used everywhere and be suitable for all soils with diversified physical, chemical and mineralogical properties. The application of the SSD procedure must consider individual soil characteristics, such as soil type and properties. The two typical SSD procedures were developed to address soils formed in two climates. The Rehovot procedure was developed to be suitable for the calcareous soils in arid and semi-arid zone soils, whereas the Bonn procedure was created to primarily handle the acid and neutral soils in humid zones. In general, the Bonn procedure appears to be unsuited for calcareous soils in arid and semi-arid zones. The Rehovot procedure has limitations in handling acid and neutral soils, especially forest soils with higher content of organic matter. 

The geochemical and mineralogical properties of the ochre-precipitates are provided in order to demonstrate their ability to concentrate arsenic and metals from the mine water. Additionally, data may support management decisions, regarding disposal or recovery of the wastes, taking into account of their environmental behaviour.

Implication in Trace Element Bioavailability Many studies have been conducted on die sorption of trace elements in cationic form onto natural soil samples, showing in these cases that ligand ions can inhibit, promote, or have no effect on their sorption. The influence of inorganic and organic ligands on the mobility of trace elements is affected by the chemical, physicochemical, and mineralogical properties of soils (Mench and Martin, 1991).
