Research In The Mineral Aggregate Industry - Introduction

The mineral aggregate industry is the world's largest mining and processing endeavor, yet it is graced with little of the romance or public awareness that accompanies mention of gold, silver, iron, copper, uranium, or aluminum mining efforts. Much of this reaction is undoubtedly due to the fact that the uses to which crushed stone and sand and gravel are normally put are not fully recognized or appreciated by the general public. Few individuals ever have occasion to purchase mineral aggregates for anything other than use for decorative shrubbery beds or walkways. They may, however, buy ready-mix concrete for a new patio, bituminous concrete for a new driveway, concrete blocks, or other building materials for a new room and never realize that the primary ingredients of their purchases are either direct or indirect products of the mineral aggregate industry. The average person driving past an operating crushed stone quarry or an active sand and gravel pit rarely realizes the economic impact the industry, represented by that operation, exercises on the general economy. He is not aware, nor does he really care, that elements of the modern comfortable environment to which he has grown accustomed rely to a great extent on the products of the crushed stone and sand and gravel industries Iron and steel, glass, cement, agriculture, and highway and building construction are but a few of the major industries to whom the products of the mineral aggregate industry are basic. Without these industries or without the stone, sand, and gravel basic to them, most of the major elements of our modern day civilization would be non-existent.
