Effects of cleaning process using toluene and acetone on water-wet
To provide insights on the impact of cleaning agents on CO 2 wettability of sandstone, water-wet and oil-wet quartz substrates were aged in acetone, toluene, and heptane, respectively. Advancing and receding contact angles of CO 2 -brine-quartz systems were measured at a constant temperature (323 K) and varying pressures (5–20 MPa).

Energy partition for grain crushing in quartz gouge during subseismic
Results show that grain crushing absorbed only 0.04 % and 0.04~0.22 % of total frictional work under dry and wet conditions, respectively. Fracture energy was determined in wet tests and only 0.003~0.05 % of fracture energy was consumed in grain crushing. Thus, grain comminution is unlikely to be an important energy sink at least for mature

Quartz sand pickling magnetic separation
Crushing before pickling is done by wet crushing. Some of them are broken by mechanical means, such as hammering and breaking. The broken materials contain a lot of mechanical iron. Mechanical iron and quartz sand react slowly in water. Usually after a few days, mechanical iron will oxidize into trivalent iron and turn red and yellow. If the acid is soaked, the oxidation of iron in the exposed

Direct Synthesis of K2SiF6 : Mn4 + Red Phosphor from Crushed Quartz
This method uses wet chemical etching of crushed quartz schist (QS) in a solution. The synthesized phosphor has particle sizes of less than with porouslike morphology. The photoluminescence and photoluminescence excitation spectroscopy show no clear difference in the spectral feature between the crushed QS-synthesized phosphor and that from single-crystalline Si wafers.
