     · Firstly keep in mind that the food coloring is only there so you can actually see what is going on. Without it the milk and dish soap will act the same but it would be really hard to see the effect with your eyes. Milk contains fat. Dish washing soap bonds to fat. So the molecules in the soap are racing around joining up with fat molecules.

    "Ball milling practice in the ore dressing industry is largely empirical. Although many investigators have worked on various of its phases the present operating methods are mostly a matter of cut-and-try with the result that the industry is not guided by its underlying principles. Consequently practice varies extensively with regard to nearly all conditions of operations.
