Divide the students in lab into groups of two; each group has to determine the specific gravity of five rocks or minerals. Be sure that all rocks and minerals are measured and that several groups measure the specific gravity of the same type of sample.
In his mineral identification tables, smith (rd,entifi,cati,on and. qual,itatioe cherai,cal, anal,ys'i,s of mineral,s, second edition, New york, 19bB) groups minerals on the basis of specific gravity but in each of the twelve groups the minerals are listed in order of decreasing hardness.
Gravity concentration methods separate minerals of different specific gravity. They are used to treat a great variaty of materials [ranging from Au ( sp. gr. ) to coal ( sp. gr. ) ]. Gravity concentration methods remained, however the main concentrating methods for iron, tungsten, tin ores and coal.
