studies in additivegrinding of minerals. Mar , many of the studies reported consisted of subjecting materials with simple geometric shapes to some type of hardness or controlled single fracture test in the presence of different chemical environments on the other hand, a number of the studies were carried out on operating industrial scale mills, without either careful control of grinding

used to study the characteristics of elements that compose minerals. For the most part, all spectroscopic techniques take advantage of the same energy principals: 1) By bombarding a sample with energy, electrons and/or neutrons can be excited.

Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture. These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite
