Introduction to Mineral Processing Concentrator Design. During the past 15 or 20 years, the trend in exploiting ore bodies has been toward larger and larger plants to handle increasingly lower grade, but larger, ore bodies. Smaller, but higher grade, ore bodies have been neglected because they did not contain sufficient ore reserves to warrant ...
