bullionbypostfor underground mining, the world g council defines between 8 and 10 grams per tonne as highquality, and 1 to 4 grams per tonne as lowquality. there is no exact definition of what is considered as high or low grade. the list below is therefore a rough guide to what may be expected.g mining process development denver mineral engineerselemental g has a specific gravity of .3, and typical ore has a specific gravity of about 2.6. all gravity concentration devices create movement between the g and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. the prospectors g pan is the most familiar gravity concentration device.what are the main methods of mining? americanthere are four main mining methods underground, open surface (pit), placer, and insitu mining. underground mines are more expensive and are often used to reach deeper deposits. surface mines are typically used for more shallow and less valuable deposits. placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.1 froth flotation fundamental principles1.1.1 grade/recovery curves while each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a grade/recovery curve. this is a graph ofwhat makes a worldclass g deposit?
