Quartz mining had existed in Arkansas since the 1800s, but Stanley believed that only a small amount of the available quartz deposits had been extracted, so he developed mining on a larger scale. During World War II, the government demand for quartz for use in radios increased and some Arkansas mines came under federal control.
An industrial mining process uses electrostatic forces to separate small particles of quartz from small particles of phosphate. Both particle types are preprocessed so that they are clean, dry, have diameters of approximately 2.5e-01 mm, and have charge-to-mass ratios (either positive or negative) of approximately Q/m = 1e-05 C/kg.They fall from a vibrating …
