​Principles of High-Power Induced Polarization (IP) Technology

High-power induced polarization technology is a geophysical exploration method widely used in mineral resource surveys. It utilizes high-frequency electrical currents to generate an electromagnetic field underground. By analyzing variations in the electromagnetic field, mineral deposits can be detected. During exploration, parameters such as current frequency, amplitude, duration, and electrode configuration are controlled to capture distinct electromagnetic field characteristics, enabling the estimation of underground mineral reserves.
