  • Mine cutoff grade | Britannica

    In mining: Delineation This is called the mine cutoff grade. And, if the material has already been mined, there is a certain grade below which it is not profitable to process it; this is the mill cutoff grade. The grade at which the costs associated with mining and mineral processing just equal

  • Cutoff grade Wikipedia

    Cut-Off grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore, while material below this grade is considered to be waste. The cut-off grade can be determined through a variety of methods, each of varying complexity. Cut-off grades are selected to achieve a certain objective

  • Rockhounding Arkansas: Trimming Mineral Specimens

    (Note: a peculiar trait of veteran mineral collectors is that they really dislike a saw cut surface on a specimen, so if you must use a saw for trimming, be prepared to take some flack from some collectors) Never trim a specimen just to make it set up nicely. You can always get a stand to accomplish this goal. Go easy Shock is the great enemy of any specimen. Anything that can be done to
