    Therefore, a metal-rich fayalite is discharged as a byproduct with copper slag in the process of the matte smelting and refining of copper. (3,4) Production of 1 ton of metallic copper generates approximately 2.2–3.0 tons of slag. It is estimated that 19–26.7 million tons of copper slag is discharged into the environment annually in China.

At this stage the investment risk may be relatively small but it is obviously undesirable to expend further funds on something that has no chance of being economic. The major risk is that a viable mining project is relinquished due to an inadequate assessment. As there is a very low probability of an exploration project proceeding to beco

    The Basics of Gold Mining and ProcessingWhat Is Gold Used for?Where Is Gold Found?The Gold Mining ProcessPlacer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is.
