Quartz, zircon, magnetite, gold are major constituents of littoral placers in Shandong province, while shell, ballstone, ilmenite, rutile being secondary.
Furthermore, the crystal structure, surface characters of quartz and clinochlore, and the solution chemistry of oleic acid as the anionic collector were analyzed.
During heating,phase transformation and expansibility of the new quartz sands and the calcined Quartz sands from two places were determined by DSC and thermodilatometry.
This observation is consistent with comments and observations of earlier investigators who indicated zoning features such as quartz masses, petalite zons and mica selvages.
Golden minerals in Carlin-type gold ore are dominated by native gold and argentiferous native gold of Au-Ag series, havehigh fineness,and are mainly enriched insulfide facies.
