the charge. This is a true electrostatic separation and it is not too effective for seed separations. The second method is to induce a charge (30, 000 - 50, 000 volts) by what is known as high intensity field. Some particles are better con ductors than others, thereby losing the induced charge more readily than poor conductors.
