  In this article, we study the circular motion of particles and the well-known
Penrose mechanism around a Kerr-Newman-Kasuya black hole spacetime. The inner
and outer horizons, as well as ergosurfaces of the said black hole, are briefly
examined under the effect of spin and dyonic charge. Moreover, by limiting our
exploration to the equatorial plane, we discuss the characteristics of circular
geodesics and investigate both photons, as well as marginally stable circular
orbits. It is noted that black hole charge diminishing the radii of photon and
marginally stable circular orbits. To investigate the nature of particle
dynamics, we studied the effective potential and Lyapunov exponent. While
inspecting the process of energy extraction, we derived the Wald inequality,
which can help us to locate the energy limits of the Penrose process.
Furthermore, we have found expressions for the negative energy states and the
efficiency of energy extraction. The obtained result illustrates that both
black hole rotation and dyonic charge contributes to the efficiency of energy
extraction.
