Quartz exists in two forms: (1) alpha-, or low, quartz, which is stable up to 573 °C (1,063 °F), and (2) beta-, or high, quartz, stable above 573 °C.The two are closely related, with only small movements of their constituent atoms during the alpha-beta transition. The structure of beta-quartz is hexagonal, with either a left- or right-handed …

Q1 and Q2 which crystallised prior to the main ore formation is generally enriched in Ti indicating high crystallisation temperatures (>500°C). Syn- and post-ore mineralisation quartz (Q3 and Q5) is depleted in Ti but shows partially very high Al, whereas Al and Ti in Q4 are below the limits of detection (LOD) and, therefore, they are not plotted.

Abstract: The purity of a quartz ore is relatively low at a SiO2 content of 97.18%, and the main impurity in the ore is Fe, Al, and Ca bearing minerals. The main component in an industrial waste bacteria (WJ) is polysaccharides, which may be used as depressors for inhibiting iron minerals in quartz flotation. Moreover, WJ belongs to …

Nether quartz ore mined using a pickaxe drops one unit of Nether quartz. If the pickaxe is enchanted with Fortune, it may drop an extra unit per level of Fortune, up to a maximum of four and an average of 2.2 with Fortune III. If the pickaxe is enchanted with Silk Touch, the ore drops itself.
