alternative is to use the ball-mill method and heat treatment to react mercury with sulfide. In this method, the mixture of mercury and sulfur powder was ground through a ball mill first, producing -HgS [23]. In the subsequent step, the -HgS was heated without O2 to induce a crystal phase switch and transform it into -HgS.
