What are the flotation methods of quartz stone?

 · In the production process, the flotation method is often used for the beneficiation and separation of feldspar and quartz. According to different pulp media, there are three main methods for flotation separation of feldspar and quartz, namely alkaline flotation, acid flotation and neutral flotation. 1. Alkaline flotation method Separation of quartz and feldspar in alkaline [.]

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

A key hurdle with this method is the state of propulsion technology. We'd need thrusters that are both powerful and long lasting. Electromagnetic thrusters which propel streams of ions may be our best hope here, but in their current state, they would only be capable of providing minuscule levels of artificial gravity, hardly enough to make a meaningful difference.
