  • Mechanical Properties of Weathered Feldspar Sandstone

    Based on this the mechanical properties and the weathering mechanisms of feldspar sandstone after drywet cycles were analyzed. 2. Material and Methods 2.1. Preparation of the Materials 2.1.1. Preparation of the Feldspar Sandstone. Given the historical value of the Yungang Grottoes the relevant department in this scenic area disallowed the collection of a large number of rock samples

  • Origin of mantle (rapakivi) feldspars experimental

    Mantled feldspars in some intrusive systems (i.e. rapakivi granites) may form by a similar dissolution and diffusioncontrolled mechanism. Textural evidence of a similar origin may be obscurred in intrusive rocks however by products of latestage magmatic and subsolidus processes. Experiments designed to simulate the dissolution of alkali feldspar during magma mixing produced

  • Flotation Behavior Collector Adsorption Mechanism of

    The mechanism of PEA acting as the collector for the separation of quartz/feldspar has been investigated. The PEA is adsorbed on the quartz surface by electrostatic and hydrogen bonding interaction with NH 3 + /NH 2 head groups while is less adsorbed on the feldspar surface due to electrostatic repulsion between the K + / Na + ions and the positively charged NH 3 + /NH 2 head

    The mechanism was investigated using microflotation tests zeta potential measurements Fourier transform infrared (FTIR) spectroscopy Xray photoelectron spectroscopy (XPS) and solution chemistry analysis. The microflotation results confirmed that the presence of gangue supernatants significantly reduces the recovery of bastnaesite during flotation with sodium oleate as a collector. The

    2.3 Dissolution mechanisms at feldsparwater interfaces. Feldspars are the most abundant minerals in Earth's crust (Table 7.1) and thus their dissolution has a major influence on the cycling of Si Al and alkali and alkaline Earth metals in the biosphere atmospheric CO 2 levels the composition of natural waters and soil formation [87]. Despite extensive investigations of feldspar

    This work intends to study the underlying physical mechanism of IRSL production. TRIRSL studies were carried out on four feldspar mineral specimens of variable chemical composition and structural state. Assuming the IR excited trapped electrons make random walks in the bandtail states and recombine by tunnelling dynamically hopping time is derived from the OFF time data of TRIRSL. This
