the problem under consideration is the design of a hundred-ton mill for treating silver ores by cyanidationgrinding mill the sulphur is partly combined as sulphide and partly as the iron sulphates, feso₄ and fe₂so₄₃. to determine the best method of procedure, preliminary tests were run on lots of 100 pounds each, this being crushed in a sampling grinder and classified into sand a slime grinding mill.At hazardous waste sites. the u.s. environmental protection agency epa seeks to protect human health and the environment from risks associated with hazardous waste sites, while encouraging development of innovative technologies such as phytoremediation to more efficiently clean up these sites. this document reports the results of phytoremediation.
Surface mining involves stripping the natural vegetation and topsoil, altering of natural topography, and deposition of waste materials e.g. tailings and waste rock at the landscape level. restoration of natural soil processes and native vegetation communities on such sites is challenging because 1 the mine grinding mill.
