    Rational Utilization of Fine Unclassified Tailings and

    The utilization of cemented tailingspaste backfill CPB by the mining industry is becoming increasingly important. However it has been difficult to analyze the economic usage of CPB for fine unclassified tailings. Therefore the physical and chemical properties of fine unclassified tailings sampled from the Sijiaying Mine were first analyzed in this study.

    Toxic chemicals used to extract the valuable materials from the ore such as the cyanide used in gold mining remain in the tailings at the end of the process and may leach out into ground water. Rock may naturally contain dangerous chemicals such as arsenic and mercury which leach into water much more readily after rock has been ground up.

    This is because the mill tailings contain the heavy metal ore constituents as well as a residual amount of radium which is produced during the radioactive decay of uranium. The radium in turn decays to produce a radioactive gas known as radon which may then be released to the environment. Because this radon is a radioactive gas which may.
