    few of those advances and developments will illustrate the possibilities of increasing the use of hardwoods in the pulp and paper industry. Hardwood harvesting and processing is generally more costly than that of softwoods because hardwoods are heavier and more difficult to saw, handle, and debark. frothing agent in the flotation process for reclaiming low grade copper- lead- and zinc-bearing ores, and as a solvent or wetting agent in a variety of textile and synthetic fibre manufacturing processes. The distilled fatty acids are used in soaps, detergents and disinfectants and as a base for lubricating greases, textile oils, cutting oils.
