Many experiments have been made under the following meauring standards on the apparent specific resistance of particle in order to study more about how electrostatic separation apparatus work.　1. To clean the measuring vessel every measurement using alcohol.　2. To give about thirty pats the vessel on the bottom after putting particle into it.　3. To put about two-kilogram weight on the electrode.　4. To use direct current for measuring (electric) power source.　5. To use the amount of particle, 5-10 g in weight.　6. To apply voltage for about 20 seconds.　7. To make a series of quick experiments not to be affected by temperature and humidity.　It is found that the measurement by those standards is useful and effective to the following.　1. The design of the electrostatic separation apparatus.　2. The inference of the effectiveness in the particle are being separated by the electrostatic separation apparatus.
