Shuikoushan Nonferrous Metals Group, located in Songbai town, Hunan Province - the industrial powerhouse of central China - is one of the largest state-owned enterprises for metal mining, ore dressing, smelting, processing and associated trades.Employing over 10,000 workers, this over-a-century-old company operates some of the biggest mines, including zinc mines in the province. ore and gangue is too intimate to effect any separa-tion at the size ranges employed in ore dressing, and thus will avoid considerable amount of, futile testing. Studies of mill products are often helpful to determine whether the loss in grade or recovery, if ever it happens, is due to intergrowth of the mine-rals or inefficient operation.
