Abstract. Three quartz-rich geologic materials—vein quartz from the Great Bear Magmatic Zone, massive quartz from the Nechalacho rare earth deposit, and quartz sands from the Chedabucto silica sand deposit along the shores of the Northern Arm of the Great Slave Lake, Northwest Territories of Canada—were evaluated for their amenability to physical beneficiation into high …
Ion-adsorption rare earth element (REE) deposits are a major source of REEs and are found mainly in China. The formation of such deposits is affected by a combination of endogenic and exogenic factors. This study investigated the effect of micro-topography on the REE distribution in four weathering profiles at different topographic sites on a knoll in Hedi, …
Apart from the above-mentioned deposits, there is certain other kinds of deposits like placer, brine and hot spring, which also contributes towards the total tungsten reserve. Placer deposits are generally formed by the mechanical as well as gravity concentration of mineral particles from weathered rocks during the sedimentation process [139 ...

The X-ray diffraction pattern of BHQ ore and the quartz particles derived after removal of iron by acid leaching of the ore is shown in Fig. 2. The diffraction pattern matches well with the standard powder diffraction pattern of hema-tite and quartz phases. It can be seen that hematite and quartz are the major mineral phases present in the BHQ ore.
The objective of efficiently recycling feldspar, quartz, and kaolin from weathered granite is accomplished.
The response of a mineral deposit to physical separation processes should always be examined from a mineralogical perspective as mineral liberation, mineral associations and the behaviour of different particle sizes can provide crucial insight into the best means of optimising the beneficiation process. 1 The Nechalacho REM deposit (Northwest ...
The distribution of rare earth elements varies significantly between rare earth ores and ionic clay deposits. This distinction is evident in Table 1 (Packey and Kingsnorth, 2016). Table 1 highlights that ionic clays have a higher presence of heavier rare earth elements, ranging from gadolinium oxide (Gd 2 O 3) to lutetium oxide (Lu 2 O 3), including yttrium oxide (Y 2 O 3).

HM-bearing materials derived from weathered and eroded bedrocks are transported by rivers to coastal areas. ... Weathering processes are particularly important in the formation and beneficiation of HM deposits, ... The gangue minerals in HM deposits are generally dominated by quartz sand/silt, clay minerals, and iron-oxide minerals, with minor ...
From the 14 quartzite samples collected across the study area, the average density value was determined to be 2.51 g/cm 3 (2510 kg/m 2). The area extent of the quartzite deposit was calculated to be 1,024,729 m 2, while the volume of the quartzite deposit is 9,079,098 m 3. The mass of the quartzite deposit was estimated to be 22,788,538 tonnes.
