This invention provides methods of producing a crosslinked lipid coating on a metal sulfide-containing material using a chemical initiator. The crosslinked lipid coating attached to the surface of the material prevents dissolution or oxidation of the material. The methods may be useful to prevent oxidation and leaking of sulfide-containing material in the environment and may be used in the control of environmental pollution.
